With previous builds, download was working correctly with standard Bluetooth.  Now Subsurface-mobile is now trying to connect using BLE, but failing to connect.  The dive computer screen continues with the waiting for PC countdown the entire time.

For dual mode dive computers we now add both LE and classic BT versions. This clearly will trigger an LE download.

That's odd. Not sure if Linus will have a moment to look at this.

Didn't you get a second entry under Paired Bluetooth Devices, that one without the LE prefix?
If not, then I messed something up :-)

That's also the LE device

This matches my experience with Shearwater devices over BLE: they seem to remember if they connected to something and then refuse to connect again.

Still the LE device

Same as above
