Unhappy serial comms error (BT) - 01-12-2021, 08:22 AM

Hi to all,

I just installed my brand new jb4 with BT adapter, works almost very well except some cases when I want to read codes, the scan process show that the DME has no error codes (I know that is false because my car live in a constant limp mode state LOL) and if I disconect the app when a try to reconnect, the app show a error message like:

JB4 Mobile unable to complete the connection cycle to your JB4.

I put the BT adapter away of any chance of interference...

Any idea of what could be happening?
