In 1.0.24 and in 1.0.25, previously paired BT devices are not always found again, even when “scan for devices” is repeatedly selected. If you long press on a paired BT item, the only option is to “unpair”. Currently, I often have to unpair and re-pair my speaker and my headphones to get them to re-connect to the PPMax.
Other Android devices allow you to tap / click to manually reconnect to a paired device. We should be able to do this in PPMax.
I also think having to reselect the “scan for devices” item is unnecessary. Scanning and discoverable should both be automatically and continuously on while in the “Bluetooth” menu.
