I am working on a project where I have to create an API which would receive data sent from sim cards over http. For this purpose I am trying to implement a program which can emulate the process so that I can execute AT commands from my java program and eventually make an HTTP Post or Get to a REST API. For this purpose I would be using my cell-phone which I have connected to my laptop using USB or bluetooth.
I am very new to this area of programming. Can you please help me regarding this?
Myself, I tried using Java Communications (but that doesn't work on 64 bit windows), HyperTerminal and ATCommand tester.
For serial port api in java consider using serialpundit, jssc or fazecast libraries (all are on github). For null modem emulation consider tty2tty/tty2comKm (linux) or com0com (windows) drivers.
