Part 1 – AT Commands for All Universal IP Devices

Chapter 2 – SMTP AT Commands

#SENDMAILi – Send Mail without Interactive Mode

Important Note: MT5692SMI-IP supports only SENDMAIL1 options.

Description: This command sends one of the 3 pre-defined email combinations. Once an IP link is established, the attached host can direct the TCP/IP stack to send an email message at any time (except when the TCP/IP stack software is already in a process using TCP resources).

The header of this email is built using the REC1/2/3, CCREC1/2/3 and SUBJ1/2/3 parameters while the body is filled in the BODY1/2/3 parameter.

This command is similar to a “send email” operation issued by a standard messaging client on a PC.

Syntax:

AT#SENDMAILi

 

Example:

Note: In #SENDMAILi, the i is to be replaced with #SENDMAIL1, #SENDMAIL2, or

 

#SENDMAIL3.

#CME ERROR: 38027

 

 

Notes: The address of the SMTP server has not been resolved by the

 

 

secondary DNS server.

 

 

TCP/IP stack is not able to reach the primary or secondary DNS

 

 

servers or a wrong SMTP server address has been entered.

 

AT#SENDMAIL1

#CME ERROR: <value>

 

 

Notes: An error has occurred during the communication with the remote

 

 

SMTP server. It may also happen during the data transfer (after the

 

 

OK message).

 

 

This error can be due to one of the following reasons:

 

 

- The DNS servers are not able to resolve the SMTP server

 

 

address

 

 

- The SMTP server is temporarily out of service

 

 

- The authentication (SMTPUN, SMTPPW) is not valid

 

 

- Email address specified in REC1 or CCREC1 is not valid

 

 

See section ‘Response messages and error codes’.

To view parameters, use #VMAIL and #VSMTP. They are also listed in #VMAILi (where i = 1, 2, or 3)
