My requirement is
- There will be one GPRS enabled (Q2686) MODEM at PC side (VB application).
- There will be another MODEM connected to Device1 through RS232 (UART1)
- Now both device will activate GPRS settings like, AT+CGATT, +CGACT, +CGDCONT etc.
- i want now to communicate with DEVICE1 through GPRS link.
Is this possible thorough AT commands not OpenAT application?
I have achieved this thing through OpenAT application, through TCP/IP.
problem in this scenario is , i required FIXED IP and PORT at server (PC based) application.
which is not recommended for my project.
Device 1 is a datalogger who wants to transfer data to server via GPRS.
please give me suggestions.
