Serial LTE Modem SENDTO of hex string bigger than 32 bytes resets the module

Hi!

Quick update, tried again. Waited a little bit longer before looking up for received bytes and it worked. I apologize for being so impacient yesterday!

By the way, it is a little bit annoying that when I misspell a command I lose my ability to send commands to the module, similar to what happened there when I asked for the received bytes before they were actually there. Is there anything I can do besides trying to be pacient and be careful with my writing? haha

Anyway, thanks for your help!

Hi Øyvind,

Adding CONFIG_SLM_UDP_PROXY=y in my prj.conf did not solve the problem, however, updating the repo did. 🙂

However, I think that the fix caused another different problem, where submitting an AT#RECVFROM command makes my Thingy:91 unresponsive to that and any other commands. The following image shows my execution: in this example I am using a command that I was able to execute successfully last week, which is a simple DNS look-up agaisnt Google servers.

Maybe I should do some other checks, but in the meantime you get my feedback too.

Thanks!

Aleix.

The fix should be in master now. Please update the master repo ( git pull) and run west update. Then add the Config as instructed in my last comment.

My apologies, you are correct, that is the documentation for the latest/master repo.

The R&D engineer has already started work and has reproduced the issue. There is a hard fault when calling k_malloc(). Have a look at this Git PR.

Can you try to add the following in your prj.conf:

CONFIG_SLM_UDP_PROXY=y

Kind regards,
Øyvind

Hello Øyvind,

I am sorry to confuse you. When I say that I am on version 1.2.99 I am refering to the following image. For instance, I just was up-to-date with the master branch of the SDK.

Does that clear out things? By the way, I do not know why would you get an error from AT#XBIND=1024, but maybe you could try without using it, or using another port, I do not use that command with any real intention.

Thanks,

Aleix.

Hi Aleix,

[quote user="Krawlow"]In that case I am currently at 1.2.99, specifically, the last time I synced with the master branch was Wednesday 22/04/2020[/quote]

Sorry, I'm a little confused. Where do you get 1.2.99 from? We do not use this for NCS, only the Zephyr repo. NCS tag v1.2.0 is likely more correct. Could you please provide a screenshot?

Anyway, I will forward your request to our R&D engineers. I am not able to set AT#XBIND=1024 as I get ERROR.

Kind regards,

Øyvind

Hi Øyvind,

By NCS I understand nRF Connect SDK, am I correct? In that case I am currently at 1.2.99, specifically, the last time I synced with the master branch was Wednesday 22/04/2020.

Tank you,

Aleix.

Hello Aleix,

What version of NCS are you working on?

Kind regards,
Øyvind
