nRF Connect SDK with External GSM 7600 with nRF52840

[Muqarrab]

Hi,
I am working on nRF52840. Previously I was using the nRF SDK as there was no library available for external GSM(MQTT) so I am moving to nRF Connect SDK. I have successfully set up the environment now I want to communicate nRF52840 with external GSM(SIMCOM 7600G) and send data over the MQTT library. How can I start? Is there any tutorial?

Hi,

 

There's no direct tutorial to do exactly what you need, but in general you should start to build your application piece-by-piece, and verify each step along the way, to ensure that the different blocks/modules are working.

Given the other thread that you have open:   FATAL ERROR: command exited with status 1 

I think that this is a good starting point, to get the communication with the external device, then add networking capabilities to this sample.

 

To get the basics up-and-running, I can strongly recommending doing the nordic developer academy courses:

https://academy.nordicsemi.com/

 

Kind regards,

Håkon

Hi,

Can I use this example to connect and send data to the MQTT server?

Håkon Alseth said:

Try moving the callback functions outside of this if preprocessor check.

Yes, I have removed it as shown in the above reply but still getting above issues

Hi Håkon Alseth 
I have made changes but getting the above issues now. Can you please check?

[Håkon Alseth]

Can you please post the updated compile log?

 

Kind regards,

Muqarrab said:

That is defined in autoconf.h if I add this file I am getting following errors.

autoconf is automatically generated based on your local configuration, and shall newer be directly included by your source code. 

Each time you add a configuration, this shall be done in your project configuration, ie. the my_application/prj.conf file.

 

I would recommend that you get to know the fundamentals of NCS, by looking at our nordic academy:

https://academy.nordicsemi.com/

 

Kind regards,

Håkon

Hi Håkon Alseth 
The First GSM_Moodem test code was working fine but now getting error for both examples

[Håkon Alseth]

Can you please post your full log?

Kind regards,

Håkon

Yes here is the main file.
