PSM active time not Correct

Good Day

I have enabled power saving on my nrf9160dk and am using NBIOT.  In doing so I found that there was a 60 sec offset to what I selected and what I wanted the active time to be.  IN doing some research I came across this question :  https://devzone.nordicsemi.com/f/nordic-q-a/87330/nrf9160-not-setting-requested-active-time 

The device is probably stuck in RRC idle for 60s before entering power saving mode.  This answer was never really solved and wanted to know if anybody found a way around this or if I will have to contact my provider?  If so, what would i need them to changed?

Kind regards,

Hassan

  • > Have you any experience with lwm2m? 

    That's a couple of years ago. Lwm2m uses CoAP, and I have much more recent experience with CoAP (and DTLS 1.2 CID).

    > if so, do you know if producing your own server is possible and worthwhile? 

    Let me split that:

    - developing an "own server": I think, the efforts are underestimated. If it's not clear, that you only need a smaller lwm2m subset, I think you will need to spend much more time than expected. It depends also on the programming language you want to use.

    - run an "own server": there are some open source projects (e.g. eclipse/leshan), but AFAIK, they don't offer a "out-of-the-box" service, so that may also end up in developing something on your own. It also requires knowledge about running such an UDP service. 

    So, I guess, it will take too much efforts. At least to begin with lwm2m, I would rather start with one of the offered services and see, how that develops.

    (I'm one of the developers behind "Eclipse/Californium", a very common CoAP/DTLS 1.2 java implementation, also used for leshan. Therefore I'm mainly using Californium to run my own services.)
