@elizarov the other day someone said

withContext(UI) { }

was equivalent to

async(UI) { }.await()

, but I am having serious problems with the latter, was that not the case?

@bj0 What "serious issues" do you have with async + await ?

the other way around, I'm reading battery level from a BLE characteristic, it works fine with `async(UI)`+`await`, returns ~86%. If I switch to using

withContext(UI)

, the read returns 0x64 (100) and then the application crashes with

E/BluetoothManagerService: btsvc manager.putLogs                                                          java.lang.ArrayIndexOutOfBoundsException: src.length=494 srcPos=0 dst.length=743 dstPos=0 length=508

Weird. You're getting the issue using BleGattCoroutines? Feel free to reach through DM to provide more details, I can probably help
