S2120 new software version V2.1

Had some problems with bluetooth connection, tried all kind of things, then I saw in the app that there was a new SW-version 2.1 for the S2120. Downloaded it, and problems are gone.

I dont know what else it does. Have not found out.

Worked for a day or three. Now I cannot connect the bluetooth from Android phone to s2120. Tried all known psw’s, 0000, 000000, 1234, 123456. Any other ideas? Tried with two different phones.
I dont want to put back the unit on top of the roof before this is solved.:slight_smile:
