[karolkadlubowski]

Component
The bug is in the mobile kotlin tutorial app.

Describe the bug
When I launch the app, there is an error in command readCharacteristic invoked in perform().

To Reproduce
Steps to reproduce the behavior:

1. Launch app
2. Give permissions
3. Connect to gopro - now in logs there should be neverending Pairing communicate and after 30s there is timeout error.

Expected behavior
There should be no errors.

Hardware

• Camera: Hero9 black
• Phone: Xiaomi Pocophone F1, Android 10 (but app was adjusted for older versions - error appearing before changed code invoked)

Additional context
Also other functions like checkStatus(receivedData.receive()) from Tutorial2SendBleCommands not working - like the command was sent, but no response came from gopro

Probably I adjusted app incorrectly to previous android version, sorry for bothering
