Bluetooth F7Micro vs F7MicroV2

I am developing a bluetooth meadow <–> mobile device program. The program works perfectly with my prototype done with an F7micro (1st gen HW), but when I connect it to F7microV2 board, things aren’t working.

I can connect to the device, but UUID for the BT service on the phone side isn’t appearing correctly.

2 hours later …

Pulled another fresh F7microV2 off the shelf. This one is working properly. Phew!!

I went back and erased flash on the non-working unit and reinstalled everything. It is still behaving badly. If you want I can send it back to the Meadow crew if they would find value in having it for debug, I’m moving on with my working hardware and will reorder another spare.
