good to see you on the forum, and thanks for introducing the GPRS shield.
The examples in the tutorial are a great start, and I'm now developing an application using the TCP socket over GPRS.
I'm using a Terminal before I migrate the routine to Arduino code, and things seem to hang when I form the HTTP GET request. Some times I see a reply, but usually I get a stall and a GPRS error message.
Have you managed to use the TCP socket?
Here's an example AT terminal transcript leading to the stall:
Following on from the "CONNECT" response, here's how I'm forming the GET request, the 24 characters that I send are set above the in KTCPSND command, and includes the end of file pattern set above with KPATTERN:
HELLO WORLD 1234 --END--
If I send the request during a telnet session with the server, I see the data echoed back. When I use the GPRS module, I get a stall, and Terminal no longer accepts further AT commands...
