Hello Sixfab community,
I’m attempting to send SMS (and hopefully MMS) messages via the Raspberry Pi 4G/LTE Cellular Modem Kit hat. I’m very new to modems and communications over cellular networks (but fairly familiar with Python, Shell, and C). I’m able to send some AT commands without issues but any directly associated with SMS fail. This post seems to hold related information but I’m not able to understand what the solution means for my situation: “Sending sms with 3g/4g base Hat - #6 by antoine.egho”. I’ve not had any success finding information about MMS messages. Also the exact modem I have isn’t listed but it is a Quectel EG25-G. The modem + Sixfab datasheets/documentation are what I have been using for the majority of my attempts thus far. Any help/guidance would be very appreciated. Thanks for reading my post!
