[Bug]: Android 12: pairing popup appears twice #429

Closed mitchellilr closed 8 months ago

mitchellilr commented 1 year ago

Hi,

When connecting to a BLE device which requires bonding, the "Tap to pair" action notification appears twice in a row.

Thanks

The popups occur after this last line in the log and produce no new logs of their own.

It is a bug in android 12^

i'll keep this issue open so it does not get refiled.

DukeJeon commented 10 months ago

same issue in Android 13

samnbd commented 8 months ago

You can call createBond() yourself just after connecting and this will resolve the issue

I double that what @samnbd suggested. Not only because "it just works" but because it will automatically circumvent any weirdness that is built into the OS flavor. At the end of the day it's about UX.

closed. i added this to the readme common problems.
