problem in AT command with smtp

[Mohamed Slama]

SA

i can send email from sim900, but i can't send attached mail because i dont know how the path of the file is placed into the instruction "AT+SMTPFILE=1,"test.txt",0"

So, where the AT command gets the path or text file ??

the instructions that i used are

AT+SAPBR=4,1

AT+SAPBR=3,1,"CONTYPE","GPRS"

AT+SAPBR=3,1,"APN","PHONEUM"

AT+SAPBR=3,1,"USER",""

AT+SAPBR=3,1,"PWD",""

AT+SAPBR=1,1

AT+SAPBR=2,1

AT+EMAILCID=1

AT+EMAILTO=30


AT+SMTPSRV="mail.unitedgroupco.com",26


AT+SMTPAUTH=1,"xx@xxxxxxx.com","12345"

AT+SMTPFROM="x@xxxxxx.com","m"

AT+SMTPRCPT=0,0,"xxxxl@xxxxx.com","Dr.Ahmed"

AT+SMTPSUB="TEST"
AT+SMTPBODY
This is test attached mail
AT+SMTPFILE=1,"test.txt",0 ===========> this is my problem from where can i get this file

AT+SMTPSEND

Read about AT+SMTPFT Transfer the Email attachment.

The modem has no supernatural connection to your computer to read a file from your harddisk. You have to transfer the data through the serial interface. AT+SMTPFILE only assigns a file name to the data you are going to transfer.
