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.
I have full experiences in bluetooth skills BLE, bluetooth core. Please contact me. Relevant Skills and Experience bluetooth core, BLE Stay tuned, I'm still working on this proposal.
Hello there. I have been working with these type of project for a long time. I can solve that problem and even provide you some additional functions that I see necessary.
