We are looking for a programmer to develop the Bluetooth communication subsystem between an IOT device and an Android\iOS (or even Windows Phone) device. Xamarin would be a plus. The Bluetooth chip in the IOT device is a Nordic nRF52840. It can be Bluetooth 4 but we would prefer Bluetooth 5 as range and power are important The system must auto-connect to a known UUID, transfer data back to the mobile device and report signal strength and disconnection.

Hello, Quick question before I can prepare my offer: Does it have to be xamarin? Would NativeScript be also ok? Sorry for being so brief but if NS is not a good option for you there is no point to waste your time. Best, Greg
