The following states can be displayed:
State of the module LED color Description
Power ON yellow This state is active when the TC3G has booted
and none of the other states are active.
GPS blue This state is active when ygpsd is activated and a
valid NMEA string is received and the internet-
state is not active.
Internet pink This state is active when ynetworkd is activated
and a valid connection to the internet exists and
the GPS-state is not active. This is also verified
by a ‘ping’ signal or a file download.
GPS + Internet green
This state is active when the ‘GPS’ state and the
‘Internet’ state are both active.
CAN traffic flashing LED, without changing
its color This state is active when there is traffic on CAN0
or CAN1.
Error blink code initialized by a 'red'
LED signal
This state is active when a ‘Goodbye’ signal from
a daemon is received or when a valid entry in the
/tmp/LED_Error file exists.
User blink code initialized by a pause
of the LED signal This state is active when a valid entry in the
/tmp/LED_User file exists.
The signal daemon checks if the variant supports:

GPS

GSM

WLAN

BT
If the variant does not support GPS, then the 'GPS + Internet' state will never be reached. Therefore, the color
of the 'Internet' state is set to 'green'.
NOTE:
The 'CAN traffic' state will not be signalized when the 'Error' state is active.
The 'User' state is signalized parallel to all other states.
NOTE:
If the LED signal is 'green', all possible states, depending on the variant, are reached.
