According to Nordic's infocenter: The device can enter Power Saving Mode (PSM) state in LTE idle mode when the <Active-Time> parameter has a valid value where at least one of bits 6–8 is set to 0.

One can tell that my device returns all zeros in those indexes.

The values you are getting indicate that PSM is not enabled. You should check this with your network provider.

I'm getting this response:

+CEREG: 5,1,"42E3","008D3602",7,,,"11100000","11100000"

One can tell that my device returns all zeros in those indexes.

The situation is unclear to me, since I'm calling lte_lc_psm_req(true);

Furthermore, I use directly the command AT+CPSMS=1,"","","10101010","00100001" (for setting Periodic-TAU timer to 10 minutes and Active-Time to 1 minute) and the test command AT+CPSMS? reads it well.

Still, the response to CEREG stays as before.

The question is if there's something I can do about it? Or is it a property of the network I'm connected to that cannot be changed?

Have you checked that the network will actually allow PSM? What values are you reading from +CEREG?

I truly need help here, would be much appreciated.

As offered in the thread, removing CONFIG_GNSS_SAMPLE_LOG_LEVEL did the trick, thanks!

But I do encounter another challenge: the LTE and GNSS share the radio, and currently the GNSS doesn't get a fix if the LTE is initialized.

I read about concurrent GNSS and LTE and tried calling lte_lc_psm_req(true), lte_lc_edrx_req(true) in the MQTT module, but it didn't have any effect.

How can I configure them to operate concurrently?

I'll try that and let you know.

Thank you!
