1.2. The Process of Sending Email

As EC2x&EG9x&EM05 modules support SMTP protocol, customers can send emails easily by
EC2x&EG9x&EM05 SMTP AT commands. The general process is as follows:
Step 1: Configure and activate a PDP context.
1) Configure <APN>, <username>, <password> and other parameters of a PDP context by
AT+QICSGP. Please refer to Quectel_EC2x&EG9x&EM05_TCP(IP)_AT_Commands_Manual
for details.
If QoS settings need to be updated, configure them by AT+CGQMIN, AT+CGEQMIN,
AT+CGQREQ
Quectel_EC25&EC21_AT_Commands_Manual, Quectel_EG9x_AT_Commands_Manual and
Quectel_EM05_AT_Commands_Manual.
2) Activate the PDP context by AT+QIACT.
3) Configure the PDP context ID for SMTP by AT+QSMTPCFG=
Step 2: Configure SMTP server and user account.
1) Configure SSL type by AT+QSMTPCFG="ssltype",<ssltype>. If <ssltype> is SSL or STARTTLS,
customers should choose an SSL context by AT+QSMTPCFG="sslctxid",<sslctxID> and
configure the <sslctxID> by AT+QSSLCFG="ciphersuite",<sslctxID>,<ciphersuites>. For more
details about these commands, please refer to Quectel_EC2x&EG9x&EM05_SSL_AT_
Commands_Manual.
2) Configure SMTP server by AT+QSMTPCFG="smtpserver",<srvaddr>,<srvport>. <srvaddr> and
<srvport> parameters depend on the mail service provider.
3) Configure account information by AT+QSMTPCFG="account",<username>,<password>.
4) Configure sender information by AT+QSMTPCFG="sender",<sender_name>,<sender_email>.
Step 3: Edit the email content.
1) Configure the recipient email address by AT+QSMTPDST.

4) Add attachments for the email by AT+QSMTPATT. The attachments can be RAM, UFS or SD
files. And the files can be uploaded to RAM, UFS or SD card by AT+QFUPL. After sending email
successfully, the file should be deleted by AT+QFDEL. For more details of these commands,
please refer to Quectel_EC2x&EG9x&EM05_FILE_AT_Commands_Manual
Step 4: Send email.
