nrf9160 at commands sequence for work with server

[Israel F]

Hi,

I'm using SLM app (on nRF9160 module) and I want to find a way to send a data (any data) to a server.

Can someone help to provide an AT commands sequence for that?

By the end , I will need to run these commands from an external MCU (I was able already to send AT commands via UART2 to the module).

Thanks in advance,

Israel

Hello Israel, 

Please read the Serial LTE Modem documentation found in nRF Connect SDK documentation.

Kind regards,

Hi,

I'm aware about the bunch of available commands for that application.

I only understood on how to connect the server (with AT#XMQTTCON=1) but I can't find a way to send a data.

Can you share a sequence of 3-4 AT commands to help me with the main goal please?

Best Regards,

Israel

update:

I finally was able to connect the nRF cloud by running:

AT#XMQTTCON=1,"nrf-my_board_number","","","a2n7tk1kp18wix-ats.iot.us-east-1.amazonaws.com",8883,16842753

But I'm still unable to send some message to the cloud terminal via LTE Link Monitor.

I also tried to run AT#XMQTTSUB="prod/7215a082-a8f3-4507-a03d-a7e2e0d55387/m",0  but this command disconnect me from the cloud.

I found last command in the community question but not sure how it should work either not sure it good for data transmition to the nRF cloud.

Need your help.

Hi, 

The nRF Cloud does not act as a MQTT broker, and therefor will not work. Please test MQTT commands towards an MQTT test broker e.g. Moquitto.
