What's wrong with the TPs? Have you tried on a laptop to see if you can catch the BT signal?
Can you see those listed inside Device Manager > Ports (COM and LPT)?
Would be nice cuz you could then connect to them and diagnose from there (calibrate also I'm sure, adj resolution, stuff like that).
For serial... I like
PuTTY but there are tons of others. Remember HyperTerminal? loll
