The LK8000/driver Nano 3 (v7.1n) ... is working fine.
After testing with the PC and PNA (Vertica V2) version wired connection, interaction with LXNAV S100 works perfectly, including task declaration (baud rate 57600 and below).
Errors from the bluetooth connection to the S100 are coming from the Nokia 8 (Android 9) bluetooth stack. Even then the 15-30pct error rate via the Nokia 8 BT... are recoverable. After a comms reset, it declares successfully. Aren't we supposed to declare tasks on the ground and not in flight :)
You are all doing an amazing job supporting and improving LK8000.
