Datasheet

Entering Nordic Beacon emulation using the sample code above, you can see the simulated
beacon in Nordic's 'Beacon Config' tool below:
AT+BLEBEACON will cause the beacon data to be stored in non-volatile config
memory on the Bluefruit LE module, and these values will be persisted across
system resets and power cycles. To remove or clear the beacon data you need to
enter the 'AT+FACTORYRESET' command in command mode.
