Thingy 91 - GPS operation and PSM time window

[Hucky]

Hi,

I have two questions:

1) After requesting PSM mode (assuming the MNO supports PSM mode for NB-IoT) and afterwards enabling GPS, does the GPS automatically detects the PSM time window and starts operation?

2) Since I could not find any API function to get information or being notified PSM time window is starting how to get this information in case I would like to synchronize the application with the modem PSM operation?

Thanks for your support!

Best regards,

Holger

Hi,

 No, unfortunately, it does not. Its up to the application when and if you start the GPS.

Since I could not find any API function to get information or being notified PSM time window is starting how to get this information in case I would like to synchronize the application with the modem PSM operation?

 This is a on-going feature request, so that the application is able to synchronize itself towards the PSM timing. Unfortunately, this is not present today (as of modem fw v1.1.0).

You can use AT commands "AT+CEREG=5" (will enable PSM intervals to be printed) and query "AT+CEREG?" to get your intervals, then check this AT command to see if you are currently active or not:

But, this is not a full fledged solution, unfortunately.

 

Kind regards,

Håkon

Thank you for the information. Is there a release roadmap for the next FW releases available showing which new features will come when?

Thanks and best regards,

Hi Holger,

 

No, unfortunately.

If you send me a direct message with your location, I can provide you with the details of your local regional sales manager (RSM), which has more information related to future development and roadmap items.

 

Kind regards,
