2. Introduction
BluNor BC832 is powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using Nordic
nRF52832 SoCs. With an ARMCortexTM M4F MCU, 512KB flash, 64KB RAM, embedded 2.4GHz multiprotocol transceiver, and an integrated antenna, it allows faster time to market with reduced development cost.
The following is a block diagram of BC832. 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.
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
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.
Bluetooth Low Energy (BLE) 4.2 Micro Module BC832Ver 1.0 Nov. 2016 draft
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.

Mounting BC832 on the Host PCB
The following figure shows recommended mounting of BC832 module on the host PCB.
•
For the best Bluetooth range performance, the antenna area of module shall extend 3.2 mm outside the
edge of a ground plane.
•
The next choice is to place module on a corner of host PCB. No ground place directly below the 3.2x7.8mm
antenna area of module.
•
For wearable, it is acceptable to place a coin battery directly below the antenna area of module. Bluetooth
range is reduced but acceptable when pairing with a smartphone on the antenna side. Bluetooth signal is
blocked on the battery side.

Bluetooth Low Energy (BLE) 4.2 Micro Module BC832Ver 1.0 Nov. 2016 draft
5. AT Commands
BC832 module is available with firmware supporting AT commands. Part number is BC832-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 P0.02 of nRF52832 (pin 13 of BC832) is pulled high, it is set to AT command mode. In AT command
mode, the host processor communicates with the processor on BC832.

Data Mode
When P0.02 of nRF52832 (pin 13) of BC832 is pulled low, it is set to data mode. In data model, BC832
provides transparent data transfer between the host processor and a remote device, for example, a
smartphone.

Bluetooth Low Energy (BLE) 4.2 Micro Module BC832Ver 1.0 Nov. 2016 draft
6. BC832 Evaluation Board
Communicating with a PC
A quick and easy way to evaluate BC832 is to use a PC as the host processor. Connect the development
board EV-BC832 to a PC with an USB cable. Then,
Set S1, BC832 is set to command mode. PC will communicate with BC832.
Set switch S1 to the other position, BC832 is set to data mode. PC will communicate with a remote
device through BC832 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 /
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.

Bluetooth Low Energy (BLE) 4.2 Micro Module BC832Ver 1.0 Nov. 2016 draft
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:
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.
