What I see on the converted frame is IMEI, Date, ICCID... but I dont know how to decode GPS data and other input output data, it seems that they are also in hexadecimal after converting.

Please help to find the right protocol.

Do you have the protocol documentation?

Hello,
No I dont have documentation :(

I don't think we support this protocol, but hard to tell for sure without the documentation.
