GPS103 sporadic reports

Hi Anton,

I've been troubleshooting what turns out to be a GPS103 Device for the better part of a week.

Monitoring the logs reveals that the unit occasionally sends one position data but in other cases only sends online state.

I'm now seeing these errors occasionally in the log file as well:

Could you say what's the cause of this error?

Those errors are not from your device.

Ok, noted.

I now have a consistent online status message every three minutes from the device however there's no GPS data.

I've followed the guide and performed numerous troubleshooting steps which yield the same result....no position data.

Is there a way for me to consult further on this matter with a view to resolving the issue?
