Remote can't find solo....

[Mark35mi]

Hi all.
Ran my solo with Samsung note 9 with solex. Calibrated compass and solo. First flight in a year? Ran one battery. Filmed. Great. Installed new battery. Remote never found solo again. Tried powering all off and powering up again. Gopro, solo, remote then solex. No go.
Ideas? Thanks.

Try un-plugging the controller battery for about 30 seconds.

Failing that
The usual 'solo not found' problem can be the SD card in the Solo.
