32u4 Won't talk to Win 10 w/o factory reset/repair

I built a CNC pendant which is really just a glorified Bluetooth keyboard with dedicated keys.

Everything works fine as long as I keep FACTORYRESET_ENABLE set to true and re-pair the device in Windows 10 every time I start it. When I set FACTORYRESET_ENABLE to 0, the pendant re-pairs to Windows just fine (confirmed by Windows and AT+BLEGETPEERADDR) but any AT+BLEKEYBOARDCODE I send just kicks back an error.

Already bumped bluefruit firmware to 0.8.1. Any Ideas?

Ping.

I know I'm not the first to do a BLE keyboard with Win 10 using a 32u4...

Did more digging... Fantastic. This problem goes back to 2017 and is still unresolved.

Adafruit - willing to trade me for a nRF52 version? I assume it doesn't have this problem...

For anyone else who hits this wall, the Bluefruit LE - nRF52832 module works fine. Had to re-write substantial portions of the code but my CNC pendant is now up and running daily.

NGL, I'm a bit disappointed in Adafruit support here in the forums. Certainly not what it was in years past. I'll be focusing on supporting my local guys @ Sparkfun for modules going forward.
