# NOTE: We need a patched UARTService class with a larger buffer. The default
# is tiny and does not work when trying to send large packets.
#from adafruit_ble.services.nordic import UARTService
# ATW: The Adafruit library has egregiously small buffers that, because of how
# the class is instantiated, can't be enlarged after the fact, so we need this
# patch.
