The email can be sent following three different procedures:
1) Opening socket with SMTP server and then sending directly SMTP commands. The following
AT commands should be issued to the Telit module:
AT+CGDCONT = 1,"IP","internet.gprs","0.0.0.0",0,0<cr> (1-GPRS context setting)
AT#USERID = "EASY GPRS"<cr> (2-Authentication setting)
AT#PASSW = "EASY GPRS"<cr> (2-Authentication setting)
AT#PKTSZ=300 (3-Socket setting)
AT#DSTO=50 (3-Socket setting)
AT#SKTTO=90 (3-Socket setting)
AT#SKTCT=600 (3-Socket setting)
For our convenience we will store all these parameters with the command:
AT#SKTSAV<cr>
Next step is activation of the GPRS context:
AT#GPRS=1<cr>
+IP: 193.199.234.255
OK
The command gives as response the IP address assigned by the network.
Now we can proceed with contacting the server with AT command for socket dial:
AT#SKTD= 0,25,"smtp.domain.com",0,0<cr>
When we receive the CONNECT indication, then we are exchanging data with the SMTP server
program on the remote host machine.
Following the SMTP protocol we proceed with the HELO presentation and mail delivery directly over
the serial line (in blu you can find the data sent by us, in violet the one received from host):
220 smtp.domain.com ESMTP Service (7.0.027-DD01) ready
