How to test GPS of NRF9160 with CMW500?

[Hannibalhz]

Dear Nordic Engineers

I would like to test the GPS of NRF9160 with CMW500.

I used a line(IPEX to SME) to connect the GPS pedestal to CMW500.

I downloaded the serial LTE modem to the NRF9160DK and then I followed these commands to set the nRF9160, but it did not reply GPS data.

So, How do I go about it? Please give me some suggestions.

Hi Hannibal,

If you are interested in testing functionality of GNSS, you can have a look at GNSS functionality test guide. You can use %XRFTEST for performing GNSS SNR test. Is mentioned GNSS SNR test suitable for you?

Is location acquired if you do not use CMW500? You can look at the example shown in Control GNSS.

Do you use A-GNSS or P-GPS in your Serial LTE Modem application?

Best regards,
