Demo Glucose Service
Dependencies: BLE_API mbed nRF51822
Fork of BLE_HeartRate by
BLE_Glucose_demo implements the Glucose Service which enables a collector device to connect and interact with.
There is a brief sample code edited with Android Studio for demo this BLE_Glucose_demo example, and it is public on github, everyone can clone it by this URL: https://github.com/Marcomissyou/BluetoothLeGlucose.git. It is convenient for you to development your BLE idea.
There is also provided apk file so you can download and install it directly then demo this code, but make sure your Android phone supports Bluetooth 4.0. /media/uploads/Marcomissyou/bleglucoseservice.apk
