 `beacon.py` is used to broadcast legacy bluetooth frames for ASTM F3411-19 basic ID, location and authentication messages. It uses drippy to read host identity files, from which an identity will be used for the basic ID messages. If an iroha private key file is specified, then it will also attempt to send location updates to the blockchain. Type `python beacon.py -h` for more information on how to use the script. Note that sudo priviledges will be required to run the hci commands in the script.
