Hi, I have Arduino MEGA, UART(TTL)/RS232 convertor and Siemens MC35.
I need to connect to internet(GPRS) via Siemens MC35 and create tcp server.
At first I found this sample in Arduino IDE (http://arduino.cc/en/Tutorial/GSMExamplesWebServer)
But there are two problems: 1-use softserial and 2 - it needs GPRS shield.
Then i found GSM/GPRS & GPS Shield Library for SIM900. It can be modified to use Serial1 (hardware serial). But when i try to connect to gprs via my Siemens MC35, i understand that this Library use AT GPRS TCP/IP command such as AT+CIICR and AT+CIFSR and other. This AT command have only SIM900 because it has to support tcp/ip protcol. My Siemens MC35 have no TCP/IP layer.
Then i found other project SerialIP (Arduino Playground - SerialIP Library) but it makes brigde via serial to connect to internet and i don't know how to use it in my case.
I try to connect with "AT+CGDCONT=1, "IP", "APN"" and "ATD 99**1#" but as i understand i need software tcp/ip library over serial.
May be there are other way to make connection and create tcp server with Siemens MC35?
Thanks, Bogdan
