MQTT over AT Commands with nRF52840

[Jacques]

Hi there,

I'm starting a new project using an nRF52840 that interfaces with a Quectel BG95 modem with AT commands. Ultimately, I need to use MQTT to an Azure cloud environment.

I would like to know which approach is recommended.

I see that there are some iot examples up until SDK16.0.0, but if I read them correctly, they are used for BLE connected modems, right?

Are there any libraries/support for MQTT over AT commands, in either the nrf52 SDKs or nRF Connect SDK? Or do I need to build it from scratch using a UART libraries?

I will use an RTOS for this project, so if I use the nrf52 SDK, I will use FreeRTOS, otherwise Zephyr.

In which direction would I find more resources and support?

Regards,

Jacques
