I know this project might seem hard to almost impossible, but I definitely know its possible. I don't care about the fact that the SIM module im using supports only 2G, It's the only sim module I have, and I just wanna make everything that I have work, plus I don't care about the image quality, something like 320p and 15fps works just fine for me, I don't want to spend more money on this.
I know this is possible because you can use TinyGSM to send HTTP post methods to web servers globally, and I know you can use the SIM800L to send images using FTP to a web server, proof here: https://www.youtube.com/watch?v=ttOM08cwJ78
If it's possible with an image, It's definitely possible with the RTMP protocol.
before anyone says that 2G/3G has been shut down in America, I already know, but that is none of my concern as I live in Europe.
