Prototype
Zephyr Powered BLE Beacon (NRF52840 DK)
BLE advertising, Zephyr RTOS, embedded firmware
iBeacon-style BLE broadcaster built on Zephyr for the nRF52840 DK.
Built a Bluetooth Low Energy beacon on the nRF52840 DK using Zephyr RTOS and the nRF Connect SDK toolchain. The firmware assembles an iBeacon manufacturer payload (UUID, major/minor, TX power) and advertises it in a non-connectable packet.
A scan response is added for a human-readable name so standard BLE scanner apps can show both the beacon identity and a friendly label. The project focuses on payload construction, advertising configuration, and validation against common mobile BLE scanners.
Highlights
- iBeacon payload construction with custom UUID, major/minor, and TX power
- Scannable, non-connectable advertising with a named scan response
- Validated broadcast format using mobile BLE scanner tooling
