nRF9160 LwM2M client example with GPS while eDRX

[Christian Zingl]

Dear Nordic DevZone community,

we modified the LwM2M client example to fit our application in a LTE-M network. Now we are trying to get GPS to work while still being able to communicate with the device, and it seems the best solution is to enable eDRX and run GPS outside the PTW.

We already tried to enable the GPS driver in the configuration menu, and we also set the eDRX parameters to eDRX cycle = "1001" (163.84 s) and PTW = "1001" (12.80) seconds. Those setttings seem to be accepted by the network - we checked this by using the AT client example. Also, we connected the GPS socket in main.c like seen in the GPS example. But we cannot get the GPS receiver to enable the LNA ('enable' connected to COEX0), which would signal an active GPS operation.

Did I miss something? I don't know where to start resolving the problem.

Thank you and kind regards

Christian

Hello Christian, 

Due to summer vacation period, the technical support staff in DevZone have minimum resources and delayed answers must be expected.

Are you getting any error messages? Are you able to provide a log output? Does the GPS sample function as expected? 

 

Those setttings seem to be accepted by the network - we checked this by using the AT client example.

 What is the response you get from the network?

Thanks

Kind regards,
Øyvind
