How do I connect and send "Hello world" to my golang (GO) TCP server from Thingy91 / nrf9160 by using LTE?

[Elias]

Hi,

I am new to the thingy91 and quite unexperienced with nordic microcontrollers in general. I am trying to figure out how to connect the thingy91/nrf9160 with LTE to my TCP server made in GO (golang) to send data with json. Are there existing libraries or samples for doing that? If it is, what modifications does it require me to do to be able to input my TCP server's IP address and send a simple string like "Hello world"?

Hi Elias,

It is not very common to use TCP directly on your application. Normally the JSON file is translated on specifically application-level protocols like MQTT, HTTP on top of TCP,  or LwM2M on top of UDP. You can find related examples below:

 nRF9160 samples — nRF Connect SDK 2.0.0 documentation (nordicsemi.com)

Since you are new to nRF9160 devices, you can start to play with them to test your sever and learn its implementation with the source codes.

TCP and UDP AT commands — nRF Connect SDK 2.0.0 documentation (nordicsemi.com)

Best regards,
