IIRC the issue here is that the host stopped allowing connection with a timeout when privacy is enabled. A solution could be to use timeout=0 in the connection parameters and then submit a k_work instead

Removed the audio label as this has nothing to do with the audio shell (it affects any version of the BT shell)
