LTE-m Reconnect after LoS

[ibiglari]

Hi,

This is a continuation of the below tickets:

•  LTE-m Reconnect after LoS 
•  LTE-M Reconnect after LoS 

After updating the modem firmware to 1.3.3 and recompiling Asset Tracker v2 with SDK 2.1, I'm afraid the problem appears not to have been resolved. I have been running tests driving around Sydney with Asset Tracker v2 running on my Thingy91, reporting to my LWM2M server. I managed to capture modem trace using a Raspberry Pi 4 and a small shell script. Looking at logs on my server, last data packet was received about 10 minutes after powering Thingy91 on, while the modem trace and logs were captured for almost an hour. I have attached both logs for your team to check.

Kind Regards,
Iman

PS: Due to the size of SUPL library, I could not use LOG_XXX functions (even in minimal mode) when using LWM2M and had to write a replacement macro, hence the filename in logs...

For some reason, the modem traces are somewhat corrupted and new logs are probably needed. However, the traces are not unreadable and the modem team has been able to find a couple of things so far.

It appears that the fixes for the issue you are experiencing is not taken into MFW 1.3.3. I have asked for more details regarding future fixes and solutions.

Another issue was also found. I will keep you updated as the internal discussion is evolving.

Hi,

Thanks for the update.

As I mentioned earlier, I am forced to capture the trace logs on an ARM machine (Raspberry Pi) using basic Linux tools like cat. That might be the reason behind the logs being "incomplete" or somewhat corrupt. I understand nRF Connect is not available for ARM. I can try and write a custom application in C / C++ to open serial port and capture trace logs, but I thought I'd ask first if your team has ever captured these traces in a Linux shell without nRF SDK tools, and if yes, maybe you could advise how they have managed to achieve that.

Looking forward to your future updates.

Cheers,
Iman

Hi Iman,

Thank you very much for generating logs. Unfortunately, these logs were not possible to read:

• 2022_12_04_09_13_AM-trace.log.gz
• 2022_12_04_09_13_AM-log.log.gz
• 2022_12_04_02_33_PM-trace.log.gz
• 2022_12_04_02_33_PM-log.log.gz

It turns out that the old logs also were more difficult to read than initially thought.

The modem team is checking out these logs now:

• 2022_12_04_05_57_PM-log.log.gz
• 2022_12_04_05_57_PM-trace.log.gz

Is there any chance you could capture modem traces using a laptop so that you could capture the standard way?

[ibiglari]

Hi,

I'm afraid that's almost impossible as my laptop is in dire need of a new battery.  I wish it were possible to compile your trace collector for ARM.

[ibiglari]

Hi,

Made a few changes to my serial port app and captured another log. This log is not a "failure" log as the device was just sitting on my table. I was wondering if you could check to see whether this log is readable or not? If it is, I will use the same piece of software to capture logs while traveling.

Yes, this log seems readable. Please capture a log of the failure scenario and we will analyze it.

[ibiglari]

Hi,

Perfect. Attached!

Hi, and thank you for the logs.

Our modem team has had a look and did not find anything wrong. They found a couple of cell losses where the modem is able to find the cell again. Unfortunately there are no time stamps in the application log indicating when the problem appears.

Could you please confirm that the problem in the latest log is that data is not successfully transferred? How often does the application send data? And how soon is it considered that the transmission is failed? We are asking because the simultaneous usage of GNSS and LTE may affect LTE functionality. There are also neighbor cell measurement requests which take some time, too.

[ibiglari]

Hi,

The application is asset tracker v2 (slightly modified to include SUPL library for faster TTFF), running in ACTIVE mode.

Last data packet was received by the server at 06:48:52 (local time). The logs end at (around) 07:05:00 (again local time) when I turned the device off.The instances of `LWM2M_RD_CLIENT_EVENT_NETWORK_ERROR` in the log are about two minutes apart.

Regarding your questions about timing, I'm not sure. However asset tracker v2 is set up, that's the way it is working.

I will capture a longer log on Sunday when I am driving out of town. Glad the logs are readable :)

[ibiglari]

Hi,

A little bit of good news. I moved my changes to asset tracker v2 to the latest SDK (2.2.0) which uses Location library instead of gnss module, and could not make the tracker lose connection permanently while driving or flying. I am planning on performing more tests within the week, but fingers crossed the issue is now resolved

I will update the ticket by Friday (or sooner if I can reproduce the issue).

Kind Regards,
Iman

Thank you for the update. It will be interesting to hear how it goes
