All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 OVERVIEW AND KEY FEATURES This Hardware Integration Guide describes both the RM186 (868MHz band for EU) and RM191 (915MHz band for US). The differences will be outlined in the Radio Specifications. Every RM1xx Series module is designed to enable OEMs to add a long range LoRa radio link as well as central role Bluetooth Low Energy (BLE) to small, portable, power-conscious devices. The RM1xx modules are enabled with Laird’s smart BASIC, an event-driven programming language that enables OEMs to make their product development quicker and simpler, significantly reducing time to market. smartBASIC enables customers to develop a complete embedded application inside the compact RM1xx hardware, connecting to a wide array of external sensors via its I2C, SPI, UART, ADC or GPIO interfaces. Based on the world-leading Nordic Semiconductor nRF51822 (BLE) and Semtech Sx1272 (LoRa) chipsets, the RM1xx modules provide ultra-low power consumption with outstanding wireless range using the LoRa radio link and local BLE connections via 3 dBm of transmit power.

Note 2: With I2C interface selected, pull-up resistors on I2C SDA and I2C SCL MUST be connected externally as per I2C standard. Note 3: SPI interface (master) consists of SPI MOSI, SPI MISO and SPI CLK. SPI CS is created by customer using any spare SIO pin within their smartBASIC application script allowing multi- dropping. Note 4: RM1xx module comes loaded with smart BASIC runtime engine FW, but does not come loaded with any smart BASIC application script (as that is dependent on customer end application or use). Laird provides many sample smart BASIC application scripts covering the services listed. Additional applications being added every quarter. Note 5: Laird suggests using Vcc of 3.3V +/-5% (3.13V-3.46V) for maximum LoRa output power. WARNING: above 3.5V, the LoRa transmitter will be disabled to maintain regulatory compliance Note 6: Deep Sleep current <1000nA (typical). Standby Doze current TBD (typical). Note 7: PWM output signal has a frequency and duty cycle property. PWM output is generated using 32-bit hardware timers. The timers are clocked by a 1MHz (1uS period) clock source. Trade-off PWM output frequency with resolution. For example: PWM output frequency of 500kHz (2uS) results in resolution of 1:2 PWM output frequency of 100kHz (10uS) results in resolution of 1:10 PWM output frequency of 10kHz (100uS) results in resolution of 1:100 PWM output frequency of 1kHz(1000uS) results in resolution of 1:1000 Refer to the smartBASIC user guide for details.

Note 2: DIO = Digital Input or Output. I/O voltage level tracks VCC. Note 3: AIN = Analog Input Note 4: DIO or AIN functionality is selected using the GpioSetFunc() function in smartBASIC. Note 5: AIN configuration selected using GpioSetFunc() function. Note 6: I2C, UART, SPI controlled by xxxOPEN() functions in smart BASIC. Note 7: SIO_21 to SIO_24 are DIO by default when $autorun$ app runs on power up. Note 8: N/A Note 9: Hidden 2-Wire SWD Programming/Debug Interface, pin22 (SWDIO) and pin23 (SWDCLK). Used for upgrading smartBASIC runtime engine FW with J-link programmer. Using this hidden 2-Wire SWD Programming/Debug Interface on customers host PCB requires header connector Samtec FTSH-105-01-L-DV, refer to section 2-Wire SWD Programming/Debug Interface for details. Note 10: Pull the nRESET pin (pin 22) low for minimum 100 mS to reset the module. Note11: SPI CS is created by customer using any spare SIO pin within their smartBASIC application script allowing multi-dropping. Note12: N/A Note13: N/A Note14: smart BASIC runtime engine has DIO (Default Function) INPUT pins, have by default PULL-UP enabled. This was done to avoid floating inputs (which can also cause current consumption in low power modes (e.g. StandbyDoze) to drift with time. In any case customer can disable the PUL-UP through their smart BASIC application. All the SIO pins (with a default function of DIO are inputs – apart from SIO_21 and SIO_23, which are outputs): - SIO_21 (alternative function UART_TX) is an output, set high (in FW). - SIO_23 (alternative function UART_RTS) is an output, set low (in FW). - SIO_22 (alternative function UART_RX) is an input, set with internal pull-up (in FW). - SIO_24 (alternative function UART_CTS) is an input, set with internal pull-down (in FW). The RM1xx module is delivered with the integrated smartBASIC runtime engine FW loaded (but no onboard smartBASIC application script). Because of this, it starts up in AT command mode by default. At reset, all SIO lines are configured as the defaults shown above. SIO lines can be configured through the smart BASIC application script to be either inputs or outputs with pull-ups or pull-downs. When an alternative SIO function is selected (such as I2C or SPI), the firmware does not allow

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 the setup of internal pull-up/pull-down. Therefore, when I2C interface is selected, pull-up resistors on I2C SDA and I2C SCL MUST be connected externally as per I2C standard. UART_RX, UART_TX, UART_CTS are Vcc logic levels (if VCC is 3.3 V, i.e. SIO pin I/O levels track VCC). For example, when RX and TX are idle, they sit at 3.3 V (if VCC is 3.3 V). Conversely, handshaking pins CTS and RTS at 0 V are treated as assertions. Pin 6 (nAutoRUN) is an input, with active low logic. In the development kit (DVK-RM1xx-SM) it is connected so that the state is driven by the host’s DTR output line. The nAutoRUN pin must be externally held high or low to select between the following two operating modes:  Self-contained Run mode (nAutoRUN pin held at 0 V).  Interactive / development mode (nAutoRUN pin held at VCC). smartBASIC runtime engine firmware checks for the status of nAutoRUN during power-up or reset. If it is low and if there is a smartBASIC application script named $autorun$, then the smartBASIC runtime engine FW executes the application script automatically; hence the name Self-contained Run Mode. Electrical Specifications Absolute Maximum Ratings Absolute maximum ratings for supply voltage and voltages on digital and analogue pins of the module are listed below; exceeding these values causes permanent damage (Table 3).

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 Note 1: Stay within internal 1.2 V reference voltage with given prescaling on AIN pin and do not violate ADC maximum input voltage (for damage) for a given VCC, e.g. If VCC is 1.8 V can only expose AIN pin to 2.1 V (VCC+0.3). Note 2: Currently, the smartBASIC runtime engine firmware only allows 10-bit mode. Note 3: ADC input impedance is estimated mean impedance of the ADC (AIN) pins. The tolerance is +/-20%. The ADC is highly sensitive to the impedance of the source. The ADC (AIN) input impedance is 200k-600k depending on your ADC gain (pre-scaling) setting. Normally, when not sampling, the ADC (AIN) impedance will have very high value and can consider it to be an open circuit. The moment ADC is sampling, ADC(AIN) impedance is 200k-600k. nAutoRUN Pin and Operating Modes Operating modes (refer to the smartBASIC manual for details):  Self-contained mode  Interactive/Development mode Table 7: nAutoRUN pin Signal Name Pin # I/O Comments nAutoRUN (SIO_25) 6 I Input with active low logic. Operating mode selected by nAutoRun pin status: If Low (0V), runs $autorun$ if it exists; If High (VCC), runs via at+run (and “file name” of application). Pin 40 (nAutoRUN) is an input, with active low logic. In the development board (DVK-RM1xx) it is connected so that the state is driven by the host’s DTR output line. nAutoRUN pin needs to be externally held high or low to select between the two RM1xx operating modes:  Self-contained Run mode (nAutoRUN pin held at 0V).  Interactive/Development mode (nAutoRUN pin held at VCC) smartBASIC runtime engine firmware checks for the status of nAutoRUN during power-up or reset. If it is low and if there is a smartBASIC application named $autorun$ then the smartBASIC runtime engine executes the application automatically; hence the name self-contained run mode.

Note 2: RM1xx: Standby Doze current TBD typical. Standby Doze is entered automatically (when waitevent statement is encountered within a smartBASIC application script). See individual peripherals current consumption in tables in section Peripheral block current consumption 4.3. Note 3: In Deep Sleep, everything is disabled and the only wake-up sources are reset and changes on pins on which sense is enabled. A reset is required to exit Deep Sleep. Note 4: Data taken with TX power 3 dBm and all peripherals off (UART OFF after radio event). Average current consumption depends on a number of factors (including TX power, VCC and accuracy of 16 MHz and 32.768 kHz crystals). With these factors fixed, the largest variable is the connection interval. Connection Interval Range: 7.5 ms to 4000 ms in multiples of 1.25 ms. For a connection event: - The minimum average current consumption is when the connection interval is large 4000 mS – The maximum average current consumption is with the shortest connection interval of 7.5 ms; no slave latency. Other factors that are also related to average current consumption include whether transmitting 6 packets per connection interval & each packet contains 20 bytes (which is the maximum for each packet) and an inaccurate 32 kHz master clock accuracy would increase the average current consumption.

Similar argument for ADC (open ADC when needed). FUNCTIONAL DESCRIPTION The RM1xx module is a self-contained LoRa/Bluetooth Low Energy product and requires only power and a user’s smartBASIC application to implement full LoRa and BLE functionality. The LoRa radio in conjunction with its external 2 dBi antenna implements a long range, low data rate connection to a LoRa gateway up to 15 km. The integrated, high performance BLE antenna combined with the RF and base-band circuitry provides the Bluetooth Low Energy wireless link to connect to local BLE sensors. The RM1xx SIO lines provide the OEM’s chosen interface connection to the wired serial/SPI/I2C/analog sensors. The user’s smartBASIC application binds the sensors to the LoRa and BLE wireless functionality. The variety of hardware interfaces and the smartBASIC programming language allow the RM1xx module to serve a wide range of wired/wireless applications, whilst reducing overall time to market and the learning curve for developing LoRa and BLE products. To provide the widest scope for integration a variety of physical host interfaces/sensors are provided. The major RM1xx series module functional blocks described below. Power Management (includes brown-out and power on reset) Power management features:  System Standby Doze/Deep Sleep modes  Brownout Reset  Open/Close peripherals (UART, SPI, I2C, SIO’s and ADC). Peripherals consume current when open; each peripheral can be individually closed to save power consumption (with a command in a smartBASIC application script).  Two-region RAM retention (No RAM retention in Deep Sleep mode)  smartBASIC command allows the VCC voltage to be read (through the internal ADC)  Pin wake-up system from deep sleep Power supply features:  Supervisor hardware to manage power on reset, brownout (and power fail).  1.8V to 3.5V supply range.

Standard accuracy clocks tend to have lower accuracy +/-250 ppm. The integrated high accuracy 16 MHz (+/-10 ppm) crystal oscillator helps with radio operation and also helps reduce power consumption in the active modes. Timers In keeping with the event-driven paradigm of smartBASIC, the timer subsystem enables smartBASIC applications to be written which allow future events to be generated based on timeouts.  Regular Timer – There are eight built-in timers (regular timers) derived from a single RTC clock which are controlled solely by smart BASIC functions. The resolution of the regular timer is 976 microseconds.  Tick Timer – A 31-bit free running counter that increments every 1 millisecond. The resolution of this counter is 488 microseconds. This counter can be accessed using the functions GetTickCount() and GetTickSince(). Refer to the smart BASIC user guide for more information. Memory for smartBASIC Application Code User has up to TBD Kbytes of data memory available for smart BASIC application script. RF  865 – 870MHz (250 – 11000 bps over the air data rate)  RM186 protocol can optionally employs 50kbps FSK when enabled by the gateway  RM191 Lora radio: 902 – 928MHz (980 – 21900 bps over the air data rate)  Bluetooth Low Energy radio: 2402–2480MHz (1Mbps over the air data rate).  BLE TX output power of +3dBm programmable (via smartBASIC command) to -20dBm in steps of 4dB.  BLE TX Whisper mode1 -30dBm (via smartBASIC command).  BLE TX Whisper mode2 -55dBm (via smartBASIC command).  BLE Receiver (with integrated channel filters) to achieve maximum sensitivity -91dBm @ 1Mbps BLE.  BLE Antenna: Integrated monopole chip antenna on RM1xx UART Interface The Universal Asynchronous Receiver/Transmitter offers fast, full-duplex, asynchronous serial communication with built-in flow control support (UART_CTS, UART_RTS) in HW. Parity checking is supported. UART_TX, UART_RX, UART_RTS, and UART_CTS form a conventional asynchronous serial data port with handshaking. The interface is designed to operate correctly when connected to other UART devices such as the 16550A. The signaling levels are CMOS logic levels that track VCC, and are inverted with respect to the signaling on an RS232 cable. Two-way hardware flow control is implemented by UART_RTS and UART_CTS. UART_RTS is an output and UART_CTS is an input. Both are active low.

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 These signals operate according to normal industry convention. UART_RX, UART_TX, UART_CTS, UART_RTS are all CMOS logic levels that track VCC. For example, when RX and TX are idle they sit at a high logic level (VCC). Conversely for handshaking pins CTS, RTS at 0 V is treated as an assertion. The module communicates with the customer application using the following signals (Figure 4):  Port /TXD of the application sends data to the module’s UART_RX signal line  Port /RXD of the application receives data from the module’s UART_TX signal line Figure 4: UART Signals Note: The RM1xx serial module output is at CMOS logic levels that track VCC. Level conversion must be added to interface with an RS-232 level compliant interface. Some serial implementations link CTS and RTS to remove the need for handshaking. Laird does not recommend linking CTS and RTS other than for testing and prototyping. If these pins are linked and the host sends data at the point that the RM1xx deasserts its RTS signal, then there is significant risk that internal receive buffers will overflow, which could lead to an internal processor crash. This will drop the connection and may require a power cycle to reset the module. Laird recommends that the correct CTS/RTS handshaking protocol be adhered to for proper operation.

SIO_24/UART_CTS 5 I SIO_24 (alternative function UART_CTS) is an input, set with internal pull-down (in FW). The UART interface is also used to load customer developed smartBASIC application script. SPI Bus The SPI interface is an alternate function on SIO pins, configurable by smartBASIC. The module is a master device that uses terminals SPI_MOSI, SPI_MISO, and SPI_CLK. SPI_CSB is implemented using any spare SIO digital output pins to allow for multi-dropping. The SPI interface enables full duplex synchronous communication between devices. It supports a three-wire (SPI_MOSI, SPI_MISO, SPI_SCK,) bidirectional bus with fast data transfers to and from multiple slaves. Individual chip select signals are necessary for each of the slave devices attached to a bus, but control of these is left to the application through use of SIO signals. I/O data is double buffered. The SPI peripheral supports SPI mode 0, 1, 2, and 3.

SPI_MISO 16 I SPI_CLK 15 O I2C Interface The I2C interface is an alternate function on SIO pins, configurable by smart BASIC command. The two-wire interface can interface a bi-directional wired-OR bus with two lines (SCL, SDA) and has master /slave topology. The interface is capable of clock stretching. Data rates of 100 kbps and 400 kbps are supported. An I2C interface allows multiple masters and slaves to communicate over a shared wired-OR type bus consisting two lines which normally sit at VCC. The RM1xx module can only be configured as an I2C master with additional constraint that it be the only master on the bus. The SCL is the clock line which is always sourced by the master and SDA is a bi-directional data line which can be driven by any device on the bus. IMPORTANT: It is essential to remember that pull-up resistors on both SCL and SDA lines are not provided in the module and MUST be provided external to the module.

The ability to output a PWM (Pulse Width Modulated) signal or FREQ output signal on up to 2 GPIO (SIO) output pins can be selected using GpioSetFunc() function. PWM output signal has a frequency and duty cycle property. PWM output is generated using 32-bit hardware timers. The timers are clocked by a 1MHz clock source. Frequency is adjustable (up to 1 MHz) and the Duty cycle can be set over range from 0% to 100% (both configurable by smart BASIC command). Note, the frequency driving each of the 2 SIO pins is the same but the duty cycle can be independently set for each pin.

RM1xx development board was used for RM1xx development and antenna performance evaluation. To obtain similar performance follow guidelines in section PCB Layout on Host PCB for RM1xx to allow the on-board antenna to radiate and reduce proximity effects due to nearby host PCB GND copper or metal covers. RM1xx on-board antenna part number: ACX: AT5020-E3R0HBANT/LF HARDWARE INTEGRATION SUGGESTIONS Circuit The RM1xx-series module is easy to integrate requiring no external components on the customer’s board apart from those required by customer for development and in customers end application. Checklist (for Schematic):  VCC External power source within the operating range, rise time and noise/ripple specification of RM1xx. Add decoupling capacitors for filtering the external source. Power-on reset circuitry within RM1xx series module incorporates brown-out detector, thus simplifying power supply design. Upon application of power, the internal power-on reset ensures module starts correctly.  AIN (ADC) and SIO pin IO voltage levels RM1xx SIO operating voltage levels are from 0V to VCC. Ensure input voltage levels into SIO do not exceed VCC also (if VCC source is a battery whose voltage will drop). Ensure ADC pin maximum inpu voltage for damage is not violated.  AIN (ADC) impedance and external voltage divider setup If one wanted to measure with ADC, a voltage higher than 3.6V then one can connect a high impedance voltage divider to lower the voltage to the ADC input pin. Other methods are to use a voltage buffer or FET transistor in conjunction with a low resistance voltage divider. High impedance values of a voltage divider connected to an AIN pin will introduce ADC inaccuracy. Laird recommends the following solution for setup of a voltage divider when used with the RM1xx ADC: – Connect a capacitor between AIN and ground (if the voltage divider presents high impedance). Normally, when ADC is not sampling, the ADC (AIN) impedance is a very high value and can be considered an open circuit. The moment ADC is sampling, ADC (AIN) impedance is 200k-600k and JP1FTSH-1051 23 45 67 8910SWDCLKVCC_IOnRESET/SWDIOGND(RM1xx Pin 22) (RM1xx Pin 23)

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 lowers the AIN voltage. However, when the capacitor is connected it should keep the AIN voltage at previous level for an adequate time period while sampling, minimizing the effect of the high resistance value of the external voltage divider. The capacitor should be big enough to hold voltage up for the required time period, i.e. 20 us for 8 bit sampling or 68 us for 10 bit sampling. If you use a FET transistor to open the current flow through the circuit momentarily before sampling, allow enough time for the capacitor to fully charge before sampling. During the sampling period, multiple samples are made and the ADC output value is the mean value from the sample pool. The sample pool is created during 20 us period for 8 bit sampling, 36 us period for 9 bit sampling, and 68 bit period for 10 bit sampling.  Two-Wire SWD Programming/Debug Interface Required if Flash Cloning will be used during production to load RM1xx smartBASIC application and/or the firmware, add 2-Wire SWD Programming/Debug Interface as detailed in section 2-Wire SWD Programming/Debug Interface  UART Required for loading customer smartBASIC application and firmware. Add connector to allow UART to be interfaced to PC (via UART –RS232 or UART- USB).  UART_RX and UART_CTS SIO_22 (alternative function UART_RX) is an input, set with internal weak pull-up (in FW). The pull-up prevents the module from going into deep sleep when UART_RX line is idling. SIO_24 (alternative function UART_CTS) is an input, set with internal weak pull-down (in FW). This pull-down ensures the default state of the UART_CTS will be asserted which means can send data out of the UART_TX line. In the case when UART_CTS is not connected (which we do not recommend).  nAutoRUN pin and operating mode selection nAutoRUN pin needs to be externally held high or low to select between the two RM1xx operating modes at power-up: – Self-contained Run mode (nAutoRUN pin held at 0V). – Interactive/development mode (nAutoRUN pin held at VCC).  Make provision to allow operation in the required mode. Add jumper to allow nAutoRUN pin to be held high or low (via 10K resistor) OR driven by host GPIO.  I2C It is essential to remember that pull-up resistors on both I2C_SCL and I2C_SDA lines are not provided in the RM1xx module and MUST be provided external to the module as per I2C standard.  SPI Implement SPI chip select using any unused SIO pin within your smartBASIC application script then SPI_CS is controlled from smartBASIC application allowing multi-dropping.  SIO pin direction RM1xx modules shipped from production with smart BASIC runtime engine FW, all SIO pins (with “default function” of “DIO”) are mostly digital inputs (see Pin Definitions Table2). Use your smart BASIC application script to change the direction of any SIO pin that is required to be an output in your design. Also these SIO pins that are inputs have by default (in FW) an internal pull-up or pull-down resistor-enabled (see Pin Definitions Table2). This was done to avoid floating inputs (which can also cause current consumption in low power modes (e.g. StandbyDoze) to drift with time. In any case customer can disable the PULL-UP through their smart BASIC application.  nRESET pin (active low) Hardware reset. Wire out to push button or drive by host. By default module is out of reset when power applied to VCC pin.

If GND flood copper exists on the top PCB layer (under of the RM1xx module), then connect with GND vias to inner GND plane and ensure that it is covered with solder mask.  Route traces to avoid noise being picked up on VCC supply and AIN (analogue) and SIO (digital) traces.  Ensure no exposed copper beneath the module (refer to land pattern of RM1xx development board). Antenna Keep-out on Host PCB  Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. Keep all mounting hardware and metal clear of the area to allow proper antenna radiation.  For best antenna performance, place the RM1xx module on the edge of the host PCB, preferably in the corner with the antenna facing the corner.  The RM1xx development board has the RM1xx module on the edge of the board (not in the corner). The antenna keep-out area is defined by the RM1xx development board which was used for module development and antenna performance evaluation is shown in Figure 6, where the antenna keep-out area is composed of PCB dielectric (no copper) sitting under the RM1xx antenna.  A different host PCB thickness dielectric will have small effect on antenna.  The antenna-keep-out defined in Host PCB Land Pattern and Antenna Keepout applies when the RM1xx is placed in the corner of the host PCB. When RM1xx-SM cannot be placed as such, it must be placed on the edge of the host PCB and the antenna keep out must be observed. An example is shown in Figure 6.

Antenna Keep-out and Proximity to Metal or Plastic Checklist (for metal /plastic enclosure):  Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40mm top/bottom and 30mm left or right.  Metal close to the RM1xx chip monopole antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. How much; that is entirely system dependent which means some testing by customer required (in their host application).  Anything metal closer than 20mm will start to significantly degrade performance (S11, gain, radiation efficiency).  It is best that the customer tests the Range with mock-up (or actual prototype) of the product to assess effects of enclosure height (and material whether metal or plastic).

Please check with Laird for the latest information before commencing a design. If in doubt, ask. BLUETOOTH SIG QUALIFICATION Overview The RM186 & RM191 modules are listed on the Bluetooth SIG website as a qualified End Product. Design Name Owner Declaration ID QD ID Link to listing on the SIG website RM186-SM Laird TBD TBD TBD RM191-SM Laird TBD TBD TBD It is a mandatory requirement of the Bluetooth Special Interest Group (SIG) that every product implementing Bluetooth technology has a Declaration ID. Every Bluetooth design is required to go through the qualification process, even when referencing a Bluetooth Design that already has its own Declaration ID. The Qualification Process requires each company to register as a member of the Bluetooth SIG – www.bluetooth.org The following is a link to the Bluetooth Registration page: https://www.bluetooth.org/login/register/ For each Bluetooth Design it is necessary to purchase a Declaration ID. This can be done before starting the new qualification, either through invoicing or credit card payment. The fees for the Declaration ID will depend on your membership status, please refer to the following webpage: https://www.bluetooth.org/en-us/test-qualification/qualification-overview/fees For a detailed procedure of how to obtain a new Declaration ID for your design, please refer to the following SIG document: https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=283698&vId=317486 Qualification Steps When Referencing a Laird End Product Design To qualify your product when referencing a Laird end-product design, follow these steps: 1. To start a listing, go to: https://www.bluetooth.org/tpg/QLI_SDoc.cfm Note: A user name and password are required to access this site. 2. In step 1, select the option, New Listing and Reference a Qualified Design. 3. Enter TBD or TBD in the End Product table entry. 4. Select your pre-paid Declaration ID from the drop down menu or go to the Purchase Declaration ID page.

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 Note: Unless the Declaration ID is pre-paid or purchased with a credit card, you cannot proceed until the SIG invoice is paid. 5. Once all the relevant sections of step 1 are finished, complete steps 2, 3, and 4 as described in the help document accessible from the site. Your new design will be listed on the SIG website and you can print your Certificate and DoC. For further information please refer to the following training material: https://www.bluetooth.org/en-us/test-qualification/qualification-overview/listing-process-updates Note: If using the RM1xx with Laird Firmware and smartBASIC script, you can skip Controller Subsystem, Host Subsystem, and Profile Subsystem. Qualification Steps When Deviating From a Laird End Product Design If you wish to deviate from the standard End Product designs listed under TBD or TBD, the qualification process follows the New Listing route (without referencing a Qualified Design). When creating a new design it is necessary to complete the full qualification listing process and also maintain a compliance folder for the design. If your design is based on un-modified RM1xx hardware, follow these steps: 1. Reference the existing RF-PHY test report from the RM1xx listing. Note: This report is available from Laird: ews-support@lairdtech.com 2. Combine the relevant Nordic Link Layer (LL). 3. Combine in a Host Component (covering L2CAP, GAP, ATT, GATT, SM). 4. Test any standard SIG profiles that are supported in the design, (customs profiles are exempt). The first step is to generate a project on the TPG (Test Plan Generator) system, select ‘Traditional Project’. This determines which test cases apply to demonstrate compliance with the Bluetooth Test Specifications, from the TPG you generate a Test Declaration, (Excel format). If you are combining pre-tested and qualified components in your design, and they are within their 3 year listing period, you are not required to re-test those layers covered by those components.
