Hello, I'm trying to make an app that will read battery percentage and show it on phone.
its actually working and shows me the battery value every but when I initialize the app I getting a pop up error message:
" Error 3300: Error 9011 in extension BluetoothLE: Unknown Characteristic "
How its unknown char? everythings defines fine also checked on the Arduino code.
it disappears after number of seconds but why its even show it? its kind of annoying.
Thanks!
