By defaultthe WiFly module now sends out a UDP broadcast to 255.255.255.255 on port 55555 at a
programmable interval. The broadcast address, port and interval are set using the “set broadcast”
commands.
The format of the packet is: 110 bytes of data:
AP MAC
address Chan RSSI
Local TCP
port
Real Time
Clock
Battery
Voltage GPIO pins
time of
day
Version and
datecode
User
DEVICEID
Boot
time
SENSOR
pins
Bytes Size
0-5 6 MAC adddress of AP that we are Associated with (for location )
6 1 Channel we are on.
7 1 RSSI
8 2 local TCP port# (for connecting into the Wifly device )
10 4 RTC value (MSB first to LSB last)
14 2 Battery Voltage on Pin 20 in millivolts (2755 for example )
16 2 value of the GPIO pins
18 13 ASCII time
32 26 Version string with date code
60 32 Programmable Device ID string ( set option deviceid<string>)
92 2 Boot time in milliseconds.
94 16 Voltage readings of Sensors 0 thru 7 (enabled with ¡§set opt format <mask>¡¨ )
NOTE: To add sensor data to the UDP broadcast message, the sensors have to be enabled using the sensor
mask. set q sensor 0xff enables all sensors.
