BluNor BT832 is powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using Nordic
nRF52 SoCs. With an ARM Cortex
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 host board. Connection to an external NFC (Near Field Communication) antenna is provided.
BlurNor BT832A, BT832F, and BT832AF are sister module of BT832. The foot print for for the main body of
module is identical. The difference are in PCB trace antenna area and memory sizes.
In this data sheets, BT832 and BT832A can be referred as BT832. BT832AF and BT832F can be referred as
BT832F. All modules BT832, BT832A, BT832F, and BT832AF can be referred as BT832.

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.
