Arduino Ble Project

I have an android battery widget, that connects to an arduino nano, through a BLE Module. The app used to work, but now, everytime I scan for a BT device, the app crashes. I also need the app to turn on bt when I scan for a bt device and keep it on, until I turn off bt and reconnect to the arduino when I turn it back on, because right now, it keeps bt on always.

Make sure that a led is turned on when the min battery level is reached and off, when the max battery level is reached.

技能: 安卓, Arduino, 低功耗蓝牙(BLE)
