STM32F103 Blue Pill + SIM7600E for MQTT over 4G — Library or Start from Scratch?

[Rima-Fahem]

Hello STM32 Community,

I’m currently in the research phase of a project where I’m using the STM32F103 "Blue Pill" with a SIM7600E module to send sensor data to an MQTT broker over 4G. I’ll be handling the communication via UART and AT commands.

My question is: should I build my own library to manage the SIM7600 and MQTT communication, or is there an existing library or resource that could help? I’ve searched but haven’t found anything solid yet, which is why I’m reaching out.

If anyone has experience with this setup or knows of a library, example code, or any useful resources, I’d greatly appreciate it!

Thanks in advance!

Welcome @Rima-Fahem, to the community of STMicroelectronics!

I am incredibly sorry to have to tell you that you are completely wrong to ask this question. For many years now, the so-called Blue Pills have not been using original STM32F103C8T6, but counterfeits - even if they are maybe labelled STM32F103. You should therefore contact the forum for Blue Pills or the manufacturer of the counterfeit.

However, you could continue to ask for support here if you are using a board with original STM32, e.g. one of the NUCLEO boards.

Good luck!
