Regarding FreeRTOS Library for Cellular modules

Libraries
1

Hello Sir,
Is there any basic library available for cellular modules to communicate with server using FreeRTOS?

Actually i gone throguh a reference manual of cellular module like BG96, SARA S4 etc. whose cellular IOT code is already developed by FreeRTOS. Thses uses secrurity system which is needed for AWS and other platform. There is no problem in it. But i want to communicate with server using inscure way. There should not be any handshaking between server and device to communicate. Just gather data from sensor and send to server.

I alredy did one iot project using Arduino and SIM808 module to send data to Adafruit server, which is basically mqtt broker platform. This is a normal way of communicating with server. I want to replace this using FreeRTOS.

I have Nucleo STM32F401re board and successfully practice freeRTOS code like task creation etc. Now i want to write a program in such way that, my one task will send data to server. Oher will check data avaibility from the server. Anoyher tasks will gather data from the sensor etc. using my nucleo board.
If cellular module disconnect then there should callback function which is take care of it etc.

If anyone did program like this or anyone having material code related to it. Please do share with me.

Your help would be appreciated.
Thank you.

Is this any help as a starting point? https://www.freertos.org/cellular/index.html

From your post it sounds like you want to use MQTT without security or authentication. That might be ok for a hobby device, but production devices or any device that sends private or valuable information should use authentication and encryption (such as TLS). However, the MQTT protocol itself is independent of any security protocol, so whether you use TLS or not depends on how your application is sending and receiving data. If you want plain text then just send and receive directly to the TCP/IP stack, rather than via a TLS context https://www.freertos.org/network-interface.html.
