Hi,

Here is the latest AT firmware : http://bbs.espressif.com/viewtopic.php?f=46&t=1123.

AT documentations : http://bbs.espressif.com/viewtopic.php?f=51&t=1022

You can test AT commands according to documentation "4B-ESP8266__AT Command Examples".

Please set "AT+CIPMUX=1" first, then "AT+CIPSTART=0,"TCP","api.openweathermap.org",80", the first parameter "0" is the link ID, only in multiple connection mode we need a link ID, in single connection mode, there is only one connection which do not need a link ID.

Thanks for your interest in ESP8266 !
