Hi, i use SIM900 libary and i want get message from TPC arduino server
All the words are spelled correctly, but the semantic content is still NULL.
What does TPC mean? Where is your code?
If the SIM900 library is used with the SIM900 chip on a shield on the Arduino which is acting as a server, it isn't clear why you are having a problem getting a message.
so.. i juse this command with PHP
Is PHP really running on your Arduino? If so, can you post a reply detailing exactly how you got the PHP engine to run on the Arduino, and which Arduino you managed that for?
