    When you want to measure the temperature of the surroundings while developing Bluetooth low-energy projects you require an external temperature sensor. implementing external sensors increases the BOM Cost and requires a bit more space. you can avoid these problems by using NRF52832 for your BLE Projects.

    in this project, I am measuring the temperature using NRF52DK And displaying the temperature on the LCD Display. for developing the firmware I have used the Arm Mbed.

    Introduction to Nordic nRF52-DK

    The nRF52 Development Kit is a single-board development kit for Bluetooth Smart, ANT, and 2.4GHz proprietary applications using the nRF52 Series SoC. This kit supports both developments for nRF52832 SoCs.


    The kit is compatible with the Arduino Uno Revision 3 standard, making it possible to use third-party shields that are compatible with this standard with the kit.

    The kit supports the standard Nordic Software Development Toolchain using Keil, IAR, and GCC. The kit also supports ARM mbed tool-chain for rapid prototyping and development using mbed’s cloud-based IDE and tool-chain with an extensive range of open-source software libraries. Program/Debug options on the kit are Segger J-Link Lite for the standard toolchain and CMSIS-DAP for mbed. The kit gives access to all I/O and interfaces via connectors and has 4 LEDs and 4 buttons which are user-programmable. A range of software examples is available from the nRF5 SDK to support Bluetooth Smart, ANT, and 2.4GHz applications.
