Bluetooth 5 Modules BT832, BT832A, BT832F, BT832AF Ver 2.12 Dec. 2018
BluNor BT832 Series is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using
Nordic nRF52 SoC. With an ARM CortexTM M4(F) MCU, up to 512KB flash, 64KB RAM, embedded 2.4GHz
multi-protocol transceiver, and an integrated PCB trace antenna. It allows faster time to market with reduced
development cost.
For applications needing limited number of IO pins, prototyping and production are easier using 16 castellated
pins. Additional 24 LGA (Land Grid Array) pins provide full access to 32 GPIOs of nRF52832.
Bluetooth 5 specifications allow reducing bandwidth to achieve up to 4X range while
maintaining similar power requirements. Range between two BT832Fs is measured at 760
meters for 1Mbps data rate, antennas at 4.2 meters above ground. BT832Fs achieve
longer range by superior antenna circuit and without an external power amplifier, not by
reducing bandwidth. Bluetooth range is much shorter in application environments with
radio frequency interference and severe multiple path interference.

2. 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 nRF52 offers a clean separation between application code development
and embedded protocol stacks. This means compile, link and run time dependencies with the embedded stack
and associated debugging challenges are removed. The Bluetooth low energy and ANT stack is a pre-compiled
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 nRF52 SoC 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 5 Modules BT832, BT832A, BT832F, BT832AF Ver 2.12 Dec. 2018
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 autonomous system peripheral
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 radio supports Bluetooth low energy and ANT. Output power is scalable from a maximum of +4dBm down
to -20 dBm in 4dB steps. Sensitivity is increased to -96 dBm to -89 dBm, depending on data rate. Sensitivity for
BLE is -96 dBm, and -92.5 dBm for ANT.
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.

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.

Mounting BT832 on the Host PCB
The following figure shows recommended mounting of BT832 module on the host PCB.
• For the best Bluetooth range performance, the antenna area of module shall extend 6 mm outside the edge
of host PCB board, or 6 mm outside the edge of a ground plane.
• The next choice is to place module on a corner of host PCB, the antenna area shall extend 6mm from the
edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of module.
• Bluetooth range performance is degraded if a module is placed in the middle of the host PCB.

Bluetooth 5 Modules BT832, BT832A, BT832F, BT832AF Ver 2.12 Dec. 2018
Mounting BT832F on the Host PCB
The following figure shows recommended mounting of BT832F module on the host PCB.
• For the best Bluetooth range performance, the antenna area of module shall extend 11.2 mm outside the
edge of host PCB board, or 11.2 mm outside the edge of a ground plane.
• The next choice is to place a module on a corner of host PCB, the antenna area shall extend 11.2 mm from
the edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of
module.
• We don’t recommend mounting BT832F module in the middle of a host PCB.

4. Bluetooth Range Measurements
Bluetooth range measurement hex codes can be downloaded from Bluetooth Range Measurements section
of this webpage.
http://www.fanstel.com/download-document/
Description of measurement site, measurement methods, and range raw data are available at:
https://www.fanstel.com/testreport/
Measurement Results
Bluetooth ranges are measured for antennas at two heights.
• 1.52 meters or 5 feet, the typical height of thermostat in the USA.
• 4.2 meters. It has 76% Fresnel zone clearance when transmitter and receiver are 1.0 Km away. Multiple
path interference caused by ground is low.
In actual application environments, Bluetooth range is much shorter because of radio frequency interference
and severe multiple path interference.
Deployment Recommendations
Most IoT devices are installed in building.
• To have the best Bluetooth data reception, direct line of sight between 2 devices should be away from
ground or wall.
• Low cost module BT832/BT832A can be used if no wall in between.
• BT832F/BT832AF should be used if a wall is between 2 devices. BT832F/BT832AF provides 15.4
additional link budget allowing signal attenuation through wall.
• If multiple walls are between IoT devices, BT832X is recommended. Comparing to BT832F, SKY66112
power amplifier in BT832X provides 16 dB higher TX power. The low noise amplifier at receiver provides
additional signal amplification.
• If one device must be installed closer to ground or a wall, install other devices far away from a wall or
ground.
• Indoor condition is different for different building. We suggest testing Bluetooth data reception in the
building with the worst case condition.
• BT Series modules have compatible soldering pad footprint. Bluetooth range can be upgraded by
replacing module. No hardware change to the host board is required if your enclosure can accommodate
the longer module.

5. AT Commands
User manual and hex codes for AT Commands supporting Bluetooth 5 features can be downloaded from AT
Command Hex Codes, Bluetooth 5 section of this web page.
http://www.fanstel.com/download-document/
AT commands can be used on UART interface and SPI interface. Advantage of SPI interface is higher speed
data rate. A battery power product can complete data transmission sooner and go back to sleep mode.
Some AT Commands are not supported by nRF52810 modules (BT832A and BT832AF).
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,
•Set S1, 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.

Evaluation Board Schematics
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.
Two inductors required for DCDC converter are inside BT832 module. You can enable DCDC to lower
power consumption.

Bluetooth 5 Modules BT832, BT832A, BT832F, BT832AF Ver 2.12 Dec. 2018
7. Preloaded Firmware
Modules are loaded with production test codes to
• enable Bluetooth transmitter for power measurement.
• set each GPIO pin to high/low for continuity measurement.
Production test codes are not erased when modules are shipped from factory. To reprogram with your codes,
follow the procedures in Reprogram with User’s Codes Section.
Starting with November 2018 production (date code 1847 or later), AT command codes for UART interface with
boot loader are used in production testing. You can use AT command codes as loaded or erase and reprogram
with your codes.
Fanstel may upgrade AT command codes and use new firmware in production testing. If you prefer to use a
specific version of AT command codes, please download and save.
AT command codes are free to use as loaded. Programming services for a specific version of codes or user’s
codes are available in factory for fee and with Minimum Order Quantity.
Reprogram with New AT Command Codes
Up to date AT command codes for UART and SPI interfaces can be downloaded from Fanstel website.
http://www.fanstel.com/download-document/
You can reprogram new AT command codes using OTA DFU (Over The Air Device Firmware Upgrade).
Reprogram with User’s Codes
To load your application codes, SoftDevice, and bootloader, you need to chiperase and reprogram modules.
An example for BT832 module:
//program BT832 Bootloader+Softdevice+Application hex
nrfjprog -f NRF52 --program BT832_AT_3in1PC181113.hex --chiperase --reset
//The file BT832_AT_3in1PC181113.hex = softdevice S1320v6.1.1+BT832_AT_UARTwithout32K+bootloader
