Hi, I'm an experienced embedded engineer of over 20 years. I have direct experience of capturing data and transferring it to a remote location via HTTP. This was via a SIM card unit, using the data channel available on any SIM contract. Message me now and I can explain what I did and how I can help with your project. Thanks, Joe

Hello, Let me review your device's documentation, I could understand how the protocol works, and how to extract the information. If it is a serial communication, it could bw a sync based communication, so it will require certain handling such as clock data, data length, etc. And I think it is all described on the doc. So let me know if you could provide it for me. Best Regards, Khamid
