The moduleâs reset pin has an optional power-on-reset circuit with a delay, which should only be required if the input power supply has a very slow ramp or tends to bounce or have instability on power up. Often a microcontroller or embedded CPU I/O is available to generate the reset once power is stable. If not, designers can use one of the many low-cost power supervisor chips currntly available, such as the MCP809 or MCP102/121. 2.2 Factory Reset Using GPIO4 It is recommended to connect the GPIO4 pin to a switch, jumper, or resistor so it can be accessed. This pin can be used to reset the module to its factory default settings, which is critical in situations where the module has been misconfigured. To reset the module to the factory defaults, GPIO4 should be high on power-up and then toggle low, high, low, high with a 1 second wait between the transitions. 2.3 2.4 Using the SPI Bus to Upgrade the Flash Memory While not required, this bus is very useful for configuring the Bluetooth modulesâ advanced parameters. The bus is required when upgrading the moduleâs firmware. The typical application schematic shown in Figure 2-6 shows a 6-pin header that can be implemented to gain access to this bus. A minimum-mode version might simply use the SPI signals (4 pins) and obtain ground and VCC from elsewhere in the design. 2.5 Module Mounting Details Figure 2-1 and Figure 2-2 show the recommended PCB footprint for the RN-41 and RN-41N, respectively. When laying out the carrier board for the RN-41 module, the areas under the antenna and shielding connections should not have surface traces, ground planes, or exposed vias. Figure 2-3 and Figure 2-4 show the recommended mounting details for the RN-41 and RN-41N, respectively. For optimal radio performance, the RN-41 moduleâs antenna end should protrude at least 31 mm beyond any metal enclosure. FIGURE 2-1: RN-41 RECOMMENDED PCB FOOTPRINT 7RS9LHZ PP PP Connection Status GPIO5 is available to drive an LED, and it blinks at various speeds to indicate status (see Table 2-1).

Pin 25 can connect directly to a coaxial cable antenna or to an antenna connector such as a U.FL or reverse polarity SMA. The PCB trace from pin 25 to the coaxial cable or connector should be less than 0.2 inches (5 mm) for minimum loss and the best impedance match. If the PCB trace is longer, it should be a 50-ohm impedance microstrip trace. Connect adjacent ground pins 24 and 26 to a low-impedance ground on the host PCB and the antenna connection. Figure 2-4 gives example host PCB layout to a U.FL connector. Modular certification of the RN171 module was performed with the external antenna types listed in Table 2-3. Refer to Section 3.0, Regulatory Approval for specific regulatory requirements by country. TABLE 2-3: TESTED EXTERNAL ANTENNA TYPES Type Monopole Gain (dBi) Yagi 15 HCI Mode Roving Networks offers the Host Controller Interface (HCI) mode in addition to the standard operational mode of its Bluetooth modules (standard mode refers to the on-board stack running on the module). In HCI mode, the on-board stack is bypassed and the module is put in a state that runs the Bluetooth baseband. The HCI provides a command reference interface to the baseband controller and the link manager, and provides access to the hardware status and control registers. This interface provides a uniform method for accessing the Bluetooth baseband capabilities. In this mode, the Bluetooth stack is no longer on-board the module. It is offloaded to the interfacing host processor. The Bluetooth module is used as a radio, performing the lower level MAC functionalities, while the application stack runs on the host processor. Using the module in HCI mode allows designers to implement profiles that are not natively supported on the Bluetooth module. Note: 0.56 Dipole www.rovingnetworks.com 2.7 Version 3.43 5/21/13 HCI mode requires a separate firmware build that must be loaded into the moduleâs flash at the factory. Is not upgradeable in the field. page 8 RN41-DS Roving Networks offers HCI mode in two hardware interfaces: ⢠HCI over UART (RN-41HCI-I/RM) ⢠HCI over USB (RN-41U-I/RM) 2.7.1 HCI OVER UART In this mode, the hardware interface between the host processor and the Bluetooth module is the UART. You must interface the flow control signals between the host processor and the Bluetooth module for the HCI interface to work. Failure to do so can cause the host processor and the Bluetooth module to become out of sync and break the Bluetooth link. 2.7.2 HCI OVER USB In this mode, the hardware interface between the host processor and the Bluetooth module is the USB. In this architecture, the Bluetooth module is the USB slave and the host processor is the USB host. Using the USB interface offers the advantage of a faster data link between the Bluetooth module and the host processor. With this architecture, it is possible to achieve Bluetoothâs theoretical maximum throughput of 3 Mpbs. 2.8 Solder Reflow Profile The lead-free solder reflow temperature and times are: ⢠Temperatureâ230° C, 30 - 40 seconds, peak 250° C maximum ⢠Preheat temperatureâ165° Âą 15° C, 90 to 120 seconds ⢠TimeâSingle pass, one time www.rovingnetworks.com Version 3.43 5/21/13 page 9 RN41-DS 2.9 Application Schematic Figure 2-6 shows a example application circuit.

Transmitter may be approved with multiple antenna types. An antenna type comprises antennas having similar in-band and out-of-band radiation patterns. Testing shall be performed using the highest gain antenna of each combination of transmitter and antenna type for which approval is being sought, with the transmitter output power set at the maximum level. Any antenna of the same type having equal or lesser gain as an antenna that had been successfully tested with the transmitter, will also be considered approved with the transmitter, and may be used and marketed with the transmitter. When a measurement at the antenna connector is used to determine RF output power, the effective gain of the device's antenna shall be stated, based on measurement or on data from the antenna manufacturer. For transmitters of output power greater than 10 milliwatts, the total antenna gain shall be added to the measured RF output power to demonstrate compliance to the specified radiated power limits. Approved external antenna types for the RN-41N module are listed in Table 2-3. www.rovingnetworks.com Version 3.43 5/21/13 page 13 RN41-DS 3.2.3 HELPFUL WEB SITES 3.3.2 Industry Canada: http://www.ic.gc.ca/ 3.3 From R&TTE Compliance Association document Technical Guidance Note 01: Europe The RN-41/RN-41N module is an R&TTE Directive assessed radio module that is CE marked and has been manufactured and tested with the intention of being integrated into a final product. The RN-41/RN-41N module has been tested to R&TTE Directive 1999/5/EC Essential Requirements for Health and Safety (Article (3.1(a)), Electromagnetic Compatibility (EMC) (Article 3.1(b)), and Radio (Article 3.2) and are summarized in Table 3-1: European Compliance Testing. A Notified Body Opinion has also been issued. All test reports are available on the RN-41/RN-41N product web page at http://www.microchip.com. The R&TTE Compliance Association provides guidance on modular devices in document Technical Guidance Note 01 available at http://www.rtteca.com/html/download_area.htm. Note: To maintain conformance to the testing listed in Table 3-1, the module shall be installed in accordance with the installation instructions in this data sheet and shall not be modified. When integrating a radio module into a completed product the integrator becomes the manufacturer of the final product and is therefore responsible for demonstrating compliance of the final product with the essential requirements of the R&TTE Directive. 3.3.1 LABELING AND USER INFORMATION REQUIREMENTS The label on the final product which contains the RN41/RN-41N module must follow CE marking requirements. The R&TTE Compliance Association Technical Guidance Note 01 provides guidance on final product CE marking. www.rovingnetworks.com ANTENNA REQUIREMENTS Provided the integrator installing an assessed radio module with an integral or specific antenna and installed in conformance with the radio module manufacturerâs installation instructions requires no further evaluation under Article 3.2 of the R&TTE Directive and does not require further involvement of an R&TTE Directive Notified Body for the final product.
