The device name has disappeared from the Android Bluetooth list.

Hi.

I had to unpair from the Android Bluetooth list by doing pm_peers_delete () when bonding.
It's ok. I know why it should.
But sometimes I can't find my paired device in the Android Bluetooth list.
I must unpair before I can pair again. But I can't unpair because I don't see the device in the list.

Eventually I have to reset the network settings.

After that I can pair again.
Why do these symptoms occur?

Hi

Thank you for the thorough explanation. I am not able to recreate this issue on my side though, can you give me a list of some phones you've been able to recreate the issue on and I'll try to find someone here who has one of them.

Also, just to make sure. You aren't deleting the bonding information from the phone side when disconnecting, correct? Because if you delete the bonding information on one side, you won't be able to bond with the device again before bonding information is deleted on both sides.

Best regards,

Simon

Hi. Simon

I test with Xiaomi Mipad 4 (Android version 8.1) & LG X400(Android version 8.1).

And I know I have to delete both side pairing information.

But the Bluetooth list doesn't show the paired device. So I can't delete it.

Change the test method a little.

2. Disconnect and unpair 'Nordic_Glucose' from the Bluetooth list in Android settings.

Do not delete the pairing information from the Bluetooth list in this order, but delete the pairing information from the DK board.
