I'm waiting for BleConnectionState.connected and still getting this Exception #21

Connection to device has not been initialized yet. You must call "connect()" and wait for "BleConnectionState.connected" before doing any read/write operation. java.lang.IllegalArgumentException: Connection to device has not been initialized yet. You must call "connect()" and wait for "BleConnectionState.connected" before doing any read/write operation. image

Do other operations work or is it just discoverChars() that fails?

edsonboldrini commented 5 years ago

Only this operation fails. To work around this, I put a delay from 2 seconds before discoverChars, but I don't think this is the best way to finish my code.

devxpy commented 5 years ago

FWIW, You don't need to call this method -- you can read/write chars anyway, using the correct UUID.

Also, please provide a full stacktrace.

Sounds nice, so I will remove my discoverChars call.

Also, please provide a full stacktrace.

ASAP I will provide my stacktrace with the error. Thanks for the help!
