Note:

The switch from data mode to command mode switch can be done by using the “at+s.”

escape sequence. This sequence can be customized by using the escape_seq

configuration variable. The sequence is case-sensitive and it must be sent in a single

complete packet with no CR or LF in the sequence.

Example:

+WIND:59:Back to Command Mode<CR><LF>

AT+S.<CR>

+WIND:60:Now in Data Mode<CR><LF>

AT+S.HTTPGET: issue an HTTP GET

AT+S.HTTPGET performs a single HTTP GET request to the named host and path. The

GET request and server response are printed on the module’s console. Any url-encoding

required for special characters in the <path&queryopts> argument must be performed by

the host prior to command submission.

Note:

NOTE: the <cr><lf> pairs in the example responses below are part of the data sent from the

server and not inserted by the module.
