Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 2. Introduction BluNor BT832 is powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using Nordic nRF52832 SoCs. With an ARMCortexTM M4F MCU, available 512KB flash, 64KB RAM, embedded 2.4GHz multi-protocol transceiver, and an integrated antenna, it allows faster time to market with reduced development cost. The following is a block diagram of BT832. Antenna circuit and main clock are integrated. All 32 GPIOs of nRF52832 can be accessed from main board. For lower power consumption at idle state, a 32.768 kHz crystal is added on the main board. Connection to an external NFC (Near Field Communication) antenna is provided. BlurNor BT832F is a sister module of BT832. The foot print for for the main body of module is identical. The only difference is a larger area for PCB trace antenna for ultra long Bluetooth operation range. Bluetooth line of sight range with a smartphone is measured at more than 100 meters. 3. Codes Development Using Nordic Tools Development tools by Nordic and other third party development tools recommended by Nordic should be used . Easy, fast and safe code development Nordic development environment for nRF52832 offers a clean separation between application code development and embedded protocol stacks. This means compile, link and run time dependencies with the Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 embedded stack and associated debugging challenges are removed. The Bluetooth low energy is a precompiled binary, leaving application code to be compiled stand-alone. The embedded stack interface uses an asynchronous and event driven model removing the need for RTOS frameworks. Over-The-Air DFU The nRF52832 is supported by an Over-The-Air Device Firmware Upgrade (OTA DFU) feature. This allows for in the field updates of application software and SoftDevice. SoftDevices The Nordic protocol stacks are known as SoftDevices and complement the nRF52 Series SoCs. All nRF52 Series are programmable with software stacks from Nordic. This bring maximum flexibility to application development and allows the latest stack version to be programmed into the SoC. SoftDevices available from Nordic: S132: Bluetooth low energy concurrent central/peripheral/observer/broadcaster stack. Development Tools Nordic Semiconductor provides a complete range of hardware and software development tools for the nRF52 Series devices. nRF52 DK board is recommended for firmware development. Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 4. Product Overview Brief description of nRF52832 SoC is provided. For full description of the SoC, please download from Nordic Semiconductor website. https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy Block Diagram Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 The following is a block diagram of Nordic nRF52832 Bluetooth Low Energy (BLE) SoC. The 32 bit ARM Cortex M4F MCU with hardware supports for DSP instructions and floating point operations, code density and execution speed are higher than other Cortex M MCU. The Programmable Peripheral Interconnect (PPI) system provides a 20-channel bus for direct and autonomouss system peripheral Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 communication without CPU intervention. This brings predictable latency times for peripheral to peripheral interaction and power saving benefits associated with leaving CPU idle. The device has 2 global power modes ON/OFF, but all system blocks and peripherals have individual power management control which allows for an automatic switching RUN/IDLE for system blocks based only on those required/not required to achieve particular tasks. The NFC block supports NFC-A tags with proximity detection and Wake-on-field from low power mode. The NFC enables Out-Of-Band (OOB) Bluetooth pairing of devices and thus greatly simplifying deployment. Photo The following is a photo of BT832 module. Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 Mechanical Drawings The followings are mechanical drawings of BT832 and BT832F. The bottom portion of module is the main body (size: 14.0 x 9.57mm) with electronic components and pins for connection to the host board. The top portion of module is for integrated PCB trace antenna. BT832 and BT832F have identical main body. BT832F has a larger antenna area to accommodate a higher performance antenna. We recommend layout the host PCB with clearance for the larger antenna area of BT832F. If the ultra long Bluetooth line of sight range of BT832F is not required, the lower cost BT832 can be installed. Two types of pins are available to meet different application requirements. • 16 castellated pins for application needing limited number of IOs. SMT equipment is not required for soldering castellated pins. • 24 LGA (Land Grid Array) pins to access all 32 GPIOs of nRF52832 when needed.

AT Commands BT832 module is available with firmware supporting AT commands. Part number is BT832-AT. Brief description of AT commands Each command line consists of a prefix, a body and a terminator. All command lines begin with the prefix AT (ASCII 065, 084) or at (ASCII 097, 116). The body is a string of characters in the ASCII range 032-255. Control characters other than(carriage return; ASCII 013) and (back space; ASCII 008) in a command line are ignored. The terminator is . There is no distinction between upper-case and lower-case characters. A command line can have a maximum length of 80 characters. It is automatically discarded if the input is longer. Corrections are made AT command is case-insensitive, following /r/n for end code. The default baud rate is 9600 one stop bit and no parity Command mode When P0.02of nRF52832 (pin 13 of BT832) is pulled high, it is set to AT command mode. In AT command mode, the host processor communicates with the processor on BT832.

In data model, BT832 provides transparent data transfer between the host processor and a remote device, for example, a smartphone. 6. BT832 Evaluation Board Communicating with a PC A quick and easy way to evaluate BT832 is to use a PC as the host processor. Connect the development board EV-BT832 to a PC with an USB cable. Then, SetS1, BT832 is set to command mode. PC will communicate with BT832. Set switch S1 to the other position, BT832 is set to data mode. PC will communicate with a remote device through BT832 Bluetooth wireless connection.

Docklight is easy to use and runs on almost any standard PC using Windows 10, Windows 8, Windows 7, Windows Vista or Windows XP operating system. Docklight software can be downloaded from the following: http://www.docklight.de/download_en.htm Suggestion for Battery Power Application Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz crystal and 2 capacitors as shown in the upper left corner of the evaluation board schematics. The 32MHz main clock won’t be active at idle state to save power. 17 Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016 7. Miscellaneous DON’T USE A MODULE WITH INTERNAL ANTENNA INSIDE A METAL CASE. USE A MODULE WITH EXTERNAL ANTENNA INSIDE A METAL CASE. ANTENNA MUST BE OUTSIDE OF A METAL CASE. FOR PCB LAYOUT: o AVOID RUNNING ANY SIGNAL LINE BELOW MODULE WHENEVER POSSIBLE, o NO GROUND PLANE BELOW ANTENNA, o IF POSSIBLE, CUT-OFF THE PORTION OF MAIN BOARD PCB BELOW ANTENNA. CONNECT MODULE GROUND TO BATTERY GROUND. 8. Contact Us United States: Fanstel Corp. 7466 E.
