micro:bit V2 cannot be flashed from Lenovo tablet - GATT WRITE NOT PERMIT

micro:bit V2 cannot be flashed from Lenovo tablet M10; error is GATT WRITE NOT PERMIT

micro:bit V2.21
Tablet Lenovo TAB M10 (3rd gen) WiFi
Bluetooth 5.0
Android 12
micro:bit application for Android V3.0.10

This tablet was used to program micro:bit V1.5 and it worked. But we failed to flash micro:bit V2.21...

All Bluetooth support in micro:bit is provided by the last program flashed, so this could be related to the program that was in V2 when you tried to pair and/or flash. To rule that out, and get a fresh start:

• Use the Bluetooth section in the tablet's Settings app to remove any existing pairings named micro:bit or DfuTarg
• Use a computer to send a hex file to the micro:bit via USB by dragging it to the MICROBIT drive.

Use the "meet the micro:bit" program hex file, or a hex file saved from a new MakeCode project (display something so you know the USB transfer has completed).

It might help to try to reset the tablet's Bluetooth as described in #79.

That was new micro:bit board, it was loaded with "meet-the-microbit-program". I do not like how annoying sounds it produces on V2...

We tried to use Lenovo M10 tablet first to program and flash simple example and we failed again and again.

Then I tried 10" Fire tablet from Amazon (FireOS based on Android 11) and I was able to program micro:bit on my first try. That is why I assume that something is wrong with Lenovo tablet or Android on that tablet or Bluetooth. As already noted, Lenovo tablet was used to program micro:bit V1 and it worked fine.

UPDATE. new micro:bit was loaded with different version of program, with "test", to test buttons, LEDs, tilt sensor, etc. We will retest with the new version of "meet-the-microbit-program".

Thanks for interesting info. Do you have any details about that different program, like a download URL or a hex file we could try?

Please post the contents of the DETAILS.TXT file from the MICROBIT drive of the micro:bit V2.

It might be useful to post the precise model variant of the M10, like TB328FU / TB328FU_EEA / TB328FU_TR, and RAM size.
