Hi jegweb - great you found this oops and thanks for sharing 
The Xiao BLE looks like a nice little board. Just wondering, have you used the BLE functionality? From what I see (without a Xiao in hand) the Xiao uses the ArduinoBLE.h library as default. For my use, I really need the Adafruit bluefruit.h or SandeepMisty NRF library, but no point going down that path unless the BT of this module works well. Be very interested in your experience on this once you get to it
