Hi, edlho

Check your bst pcb adapter back side, if you can see "V1.1" then no need solder, otherwise need solder for 4.4.x uart commnucation.

My pcb works well and I had no problem, however it is V1.1 and will weld resistance 100K and still works well, but still I have not tested with 4.4.x than you ... I recommend leaving it well or remove the resistance?
