+ === Using Packet Link Mode
+
+ All AltusMetrum flight computers that have a radio can
+ communicate with the ground station software for
+ configuration and other operations using the Packet
+ Link mode. This uses radio communication instead of a
+ USB cable. To set this up, the ground station software
+ must be configured to the correct data rate, frequency
+ and callsign.
+
+ You can monitor Packet Link mode from TeleBT or
+ TeleDongle by watching the LEDs. Each time the device
+ transmits, the red LED will flash. When the link is
+ busy, or when the link is not working, the device will
+ transmit 10 times per second, so the LED will flash
+ rapidly. When the link is working and there is no data
+ to send, the link will flash once per second, and the
+ LED will flash more slowly.
