A server application running on the Internet access to the computer, another one with 4 g module of embedded devices, want to let the server program with 4 g communication between modules of hardware, transfer files and images,
Would like to ask:
1, what is the communication process?
2, the server is it all right, or also want to use 4 g device?
3, how server-side programs and 4 g communication module equipment, how to use the TCP?
Is there a case, or the more detailed, the better, thank you
