These bugs can be caused by a variety of issues. “Error writing to non-volatile memory” for instance, can be a caused by a bad WDSS, or by a non-compliant USB stack.

However, Logger Pro 3.8.4 has a lot of bluetooth improvements, including stronger stack detection and fall-overs for various commands, so a good place to start on this issue is by upgrading.
