[Android] Chiptool app on Xiaomi tab 5 is crashing while pairing with Thread devices about connectedhomeip HOT 5 CLOSED

Any updates? or information is this issue affecting more then this device (is it SoC, manufacturer etc issue?)

Hi, @igor90ns

It seems to me we can suppress ChipDeviceControllerException when invoking pairing API for android, but the root cause is related to BLE Gatt Service, you may check whether svcId is null or not with your debugging build.

You mention "On all other devices it seems that commissioning works fine", I assume this fails with the particular thread device, which seems to soemthing wrong on its BLE configuration. with that thread device

UUID svcUUID = convertBytesToUUID(svcId);
BluetoothGattService sendSvc = bluetoothGatt.getService(svcUUID);
if (sendSvc == null) {
  Log.e(TAG, "Bad service");
  return false;
}

BluetoothGattService subscribeSvc = bluetoothGatt.getService(svcUUID);

UUID svcUUID = convertBytesToUUID(svcId);
BluetoothGattService sendSvc = bluetoothGatt.getService(svcUUID);
if (sendSvc == null) {
  Log.e(TAG, "Bad service");
  return false;
}

I am using libraries and i cant access values, but when I set breakpoint i can see that var6 is null
UUID var5 = convertBytesToUUID(svcId);
BluetoothGattService var6 = var4.getService(var5);
if (var6 == null) {
Log.e(TAG, "Bad service");
return false;

No, it means that I have tried same use case with different mobile devices (Samsung S22, Google Pixel 7, Huawei P9 Lite) and it works correctly with thread devices, but when i try same on Xiaomi Tab 5 (model 21051182g) with android 13 chiptool app crashes.

Regarding thread device, I have used Nanoleaf bulb and led strip (matter certified devices)

I also found a similar issue. (LG Valvet in Android 12 version.)
Can you check if it is modified with the PR I uploaded?

@igor90ns feel free to reopen or create a new issue if it is still problematic, thanks
