nRF9161-DK SMS sample. message not receiving to controller on time

RE: nRF9161-DK SMS sample. message not receiving to controller on time

I upgraded the modem FW. Situation did not change. After some additional testing / debugging I conclude that indeed the network provider does not forward the SMSes reliably. I need to provide a demo to the customer showcasing remote control of the device. I saw that there are no examples with nRF Cloud and this SMS does not work for me as mentioned above. Do you have any other examples which could be useful to me?

As I said, I couldn't see any incoming pages for the device from the network, so to me, it looks like the network doesn't forward the SMSes other than immediately after the attach.

Also, I noticed that you are using a pre-release version of the modem FW. Just to be sure, could you try to upgrade to mfw v2.0.1?

from a minute to 10. Does not seem to be the network as the modem seems to be receiving at the right time but the callback is only triggered after device reset (this is my conclusion after debugging and checking the "received" time):

In the above screenshot I sent sms to initialized device at 10:13, callback was not triggered.

I waited for 5 mins, and at 10:18 I reset the device. Callback was triggered and gave the above result.

I checked with a debugger, MCU was not crashed, operated normally. As you mentioned, PSM is not enabled. Any other ideas?

How long do you wait until you reset the device?

Towards the end of both logs I can see the device reveices some pages from the network, but none of them are for the device. So to me, it looks like the problem is somewhere in the network.

Hello, this is Balis - colleague of Povilas. We are both working on the same case. Attached are the modem traces.

Hi, and sorry for the late reply,

A public holiday here in Norway meant that we were low on staff at the end of the last week.

According to the log, you do not have PSM enabled, so that isn't the issue.

Could you take a modem trace, so that we can have a look at the traffic between the device and the network?

Hi,

It's possible that the modem has gone into a power saving mode (such as PSM), where it has turned the radio off for a while.

Can you enable some more logging, so that we can check if that is the case?

CONFIG_LTE_LINK_CONTROL_LOG_LEVEL_DBG=y

Best regards,

Didrik
