DeactivateDaemon ydatad ylogd ysmsd
Example Signals for Normal Operating Mode
The signal below starts with the "maximum reachable" state (e.g. GPS + Internet). After one second, there is
traffic on the CAN bus and the LED starts flashing.
If the GPS signal is lost, the signal switches to the color of the 'Internet' state. When there is no more traffic on
the CAN bus the LED stops flashing as well.
Example Signals for the User Mode
If there is a valid entry in the 'LED_User' file, the signal daemon starts showing the 'User' state and the state of
the module alternately.
The signal below shows alternating the 'GPS + Internet' state and the the 'User' state.
The matching entry in the 'LED_User' file would be: 4 3
{ echo "4 3" > /tmp/LED_User }
The signal below shows alternating the 'GPS' state and the 'User' state.
The matching entry in the 'LED_User' file would be: 2 2
{ echo "2 2" > /tmp/LED_User }
This signal shows alternating the 'Error' state and the 'User' state.
The matching entry in the 'LED_Error' file would be: 5 3
The matching entry in the 'LED_User' file would be: 6 0
Example Error Signals
If there is a valid entry in the 'LED_Error' file, the signal daemon switches to the 'Error' state.
The signal below indicates that the error has something to do with the 'GPS' state because it flashes 'blue'.
The matching entry in the 'LED_Error' file would be: 4 2
The signal below indicates that there is something wrong with the 'Internet' state because it flashes 'pink'.
The matching entry in the 'LED_Error' file would be: 5 3
