I'm trying to setup my USB GPS with Kura PositionService. The GPS is working fine and the fix is correct as I can see from gpsd linux daemon, but if I enable the Kura PositionService with the correct port (I've tried both serial and USB) and other connection params, I get this error:

[GpsSerialCommunicate] ERROR o.e.k.l.p.GpsDevice - Exception in parseNmeaSentence

How can I solve this issue?

Hello Davide,

The PositionService cannot be run in parallel with gpsd. If you are using gpsd, you should leave the PositionService disabled. If you want to use the PositionService, you should stop the gpsd daemon.

Thanks,

Hello David,

many thanks for your reply.
I can confirm you that no gpsd process is running, but the error of PositionService is still there. Do you have any other idea?

I would recommend changing your log level to "DEBUG" in /opt/eclipse/kura/kura/log4j.properties, then restart Kura. This should create a debug statement in /var/log/kura.log that looks like:

GPS RAW: <nmea_string>

This should indicate which string the PositionService is having trouble parsing. If that works, post the failing string and I will take a look.

Thanks,
--Dave

Hi David,

I solved the issue...I don't know why, but the GPS module switched to vendor-binary mode; after turned it back to NMEA mode, everything went well. Thank you again for your support.
