Implementing an AT# driver does not require a big investment and offers a short time-to-market option for connecting devices wirelessly over the Internet.

The AT# interface makes it possible to trigger complex actions with only one single command.

Download a FTP file

The FTP parameters are stored once in specific AT# values : FTP server name, login and password, name of the file to download, active or passive mode...

"AT#FTPGet" automatically connects to the FTP server, plays the authentication, transfers the file from the remote FTP directory to the serial port and finally closes the FTP session.

Send an email

The email account parameters are stored in specific AT# values : SMTP server name, login and password if any, pre-defined recipients, pre-defined subject, specific SMTP port...

"AT#SendMail" automatically connects to the SMTP server, plays the authentication, sends the pre-defined email header, transfers the data received on the serial port as the email body and finally closes the SMTP session.
