EDGEBOX-ESP100 GSM Webserver

Hello, I would like to create a simple webserver on an edgebox-esp100, accessible from the GSM connection (via private APN).
It seems that the AT+SERVERSTART command on the A7670 chip creates a server but I don’t know how to link it to the code. Basically, I want to send a command to enable or disable one of esp output. Thank you in advance for your help !
