Trying out 3.1.3 Tower using Samsung note 8 -> 3drBT ->3dr radio… I get the socket error… All works very well using DP2 with BT… I can use USB but like the freedom of BT for gain antennas on 433…
Thanks
Apology
I went to settings… I had 2 HC-06 modules paired… I unpaired all of them and re-paired the active BT module. Now BT connects well…
