Troubleshooting
Red LED/blinking
Indicative of a self-test failure. As of build 6058, using the $status command will show what
failure code is present, but this does not survive resets.
i - Iridium - Modem cannot communicate with CPU of XMR
f - Flash - Flash error is showing as a full chip; erasing the chip may resolve this issue.
No Iridium messages (assuming no self-test failure)
Determine the nature of the issue (antenna-related, system related or location-related)
o
Ensure the device's Iridium IMEI is active on the Iridium network with your service
provider.
o
Ensure the device is provisioned to send messages where intended.
o
Change the location of the device; place the device in an area with as much total view of
the sky as possible.
Dumping the flash memory will display all Iridium sessions that occurred, regardless of
success.
Messages are not readable in email (in binary)
Messages are in compressed binary format by default; use the $msgenable command to change
the format to ASCII.
o
Note that this would only apply to GPS positions and not data that is relayed.
No GPS/poor GPS
The XMR’s start-up message lists the firmware version of the GPS chip. If the GPS version
is not displayed, the CPU is unable to communicate with the GPS chip.
Change the location of the device; place the device in an area with as much total view of
the sky as possible.
Dumping the flash memory will display all GPS sessions that occurred, regardless of
success.
o
Check the number of satellites seen (greater than 4), SNR level (greater than 38), time
the GPS session was on (less than 60 seconds for first fix, less than 20 for other fixes).
The response to the $sysinf command shows most recent occurrence of these stats.
Device is transmitting too frequently/not enough
Check timer intervals with $timer command
Check timer currently being used with the $status command (Returns TMde=0)
Change timer interval as required
Device is going into alarm when it should not
Watch circle is enabled when it should not be enabled.
o
Use $switch c 0 to turn off watch circle functionality
o
Use the $setcircle command to adjust a circle that is of an inadequate size or location.
