Hi everyone, I'm trying to use AWS IoT with SIM7600 over MQTT. It looks like the AT commands to send a certificate (ex: AT+CCERTDOWN) are not available anymore in the new firmware of SIM7600. So I can not use AWS IoT service since it only works with this certificate. Basically the new SIM7600 firmware only allows not secure MQTT communication...
Now I thought it would be easy to get the old firmware, but the only way to have it is to contact SIMCOM support team. I've been tying to reach them by e-mail for more than a week, but I never receive any answer. I'm a bit desesperate as they are the only ones who can give me this old version of the software.
Since I really have to finish this project soon, I was wondering if any of you had this old firmware version, and if you could share it with me?
Thank you very much ,
I'm using SIM 7600E-H and SIM 7600G-H. In this version SIM7500_SIM7600 Series_AT Command Manual _V1.08 of the manual, the commands still exist.
