2. Introduction
BluNor BT832 is powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using Nordic
nRF52832 SoCs. With an ARMCortex
TM
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 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 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.

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.

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.

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.

5. 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 <CR>
(carriage return; ASCII 013) and <BS> (back space; ASCII 008) in a command line are ignored.
The terminator is <CR>.
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.

Data Mode
When P0.02 of nRF52832 (pin 13) of BT832 is pulled low, it is set to data mode. 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 a testing, analysis and simulation tool for serial communication protocols (RS232, RS485/422 and
others). It allows you to monitor the communication between two serial devices or to test the serial
communication of a single device. Docklight significantly increases productivity in a broad range of industries,
including automation and control, communications, automotive, equipment manufacturers, and embedded /
Bluetooth Low Energy(BLE) 4.2 Module BT832/BT832FVer 1.0 Nov. 2016
17
consumer products. 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.

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:
