SIM900 GPRS EMAIL AT Commands

Watch this video if you want to see the live demo,

 

Before you begin make sure your SIM900 GSM module has acquired the network and it is ringing when you make a call to it. Then test the basic AT commands and then proceed further.

Once you are ready, you can start by first setting up the GPRS connection as follows,

Text in RED is typed by me and text in GREEN is the response from SIM900 module.

 Setting up GPRS connection

Set the connection type to GPRS

AT+SAPBR=3,1,”Contype”,”GPRS”

OK

 

Set the APN to to “www” since i am using a Vodafone SIM card, It might be different for you, and depends on the network

AT+SAPBR=3,1,”APN”,”www”

OK

 

Enable the GPRS

AT+SAPBR =1,1

OK

 

Query if the connection is setup properly, if we get back a IP address then we can proceed

AT+SAPBR=2,1

+SAPBR: 1,1,”100.120.204.132″

OK
