How to make a simple program testing LTE

[Lucas-HippyDev]

Hello Everyone

I am really new to everything here, i just got nRF 9160dk board.

Can anyone please tell me the step-by-step method on how to make a very simple program who just connects to LTE and send a simple request.

All the samples code are using a lot of libraries and it confuses me. I just want to create a program who works on this board so I can test the same modem on a board that I created.

Any help will be greatly appreciated.

Thanks in advance.

Hi Lucas,

This is quite an open topic, as you have seen, LET connection is just like internet cable. On top of IP protocol, you have so many choices for your application development.

I suggest you read through the nRF Connect SDK document related to nRF91, especially Working with nRF91 Series and nRF9160 samples. Pay attention to the following sample to get basic knowledge of specific fields:

Commands on LTE Connection: nRF9160: AT Client

Data Transmission with MQTT: nRF9160: Simple MQTT

A read-to-use application example: nRF9160: Asset Tracker v2

After learning them, you would have basic knowledge with nRF91 related development, then you can decide what to hand on next.

Good luck with your development! Feel free to ask for help on Devzon if you have any further questions.

Best regards,

Charlie

Hi!

First of all, thank you for your answer!

Indeed, the sample codes are working great, but all of them are accompanied with the whole kernel specific to the nRF9160.

My issue is that I have designed a board using the same modem and I just want to write a code to verify if I can just send a very simple request. So I can test it on the nRF9160 and on my board.

In short, where can I find the informations to create this code from scratch?

The most basic code who just connects to LTE and send a request.

Best regards,

Hi Lucas,

Please define the "very simple request". Is it at commands, TCP/IP packages, MQTT/CoAP/HTTP/LWM2M messages, or something else?

If you need only one example to test LET, I would suggest nRF9160: AT Client. 

Best regards,
