Firmware for laboratory robot aiding the sampling and preservation cycle in blood donation facilities.

I wrote the BLE connectivity module for communicating the wristband with custom client Android App. Also I wrote firmware for a dedicated flashing station for production environment.

Main features:

• 5 consecutive BLE connections
• custom command and status BLE GATT services and characteristics
• nRF51 ARM CortexM chip
