## AT+WEBSERVER

Source: [https://docs.qualcomm.com/doc/80-Y8730-7/topic/http_server_at_commands.html](https://docs.qualcomm.com/doc/80-Y8730-7/topic/http_server_at_commands.html)

This command starts or stops the web server.

### Operation type

Query/Set/Execution

### Syntax

| Command | Response |
| --- | --- |
| AT+WEBSERVER | +WEBSERVER: use AT+WEBSERVER=&lt;enable&gt;,&lt;server\_port&gt;<br><br><br>                <br>OK |
| AT+WEBSERVER? | +WEBSERVER: &lt;state&gt;,&lt;scheme&gt;,&lt;server\_port&gt;<br><br><br>                <br>OK |
| AT+WEBSERVER=&lt;enable&gt;,&lt;server\_port&gt; | OK |

### Defined values

- `<enable>`: Enable or disable the web server.
    - `0`: Disable
    - `1`: Enable
- `<server_port>`: Web server port number. Range: [1, 65535]. Required when &lt;enable&gt;=1
- `<state>`:  (Query response only) Current server state
    - `0`: Stopped
    - `1`: Running
- `<scheme>`: (Query response only) Active prototol scheme
    - `0`: HTTP
    - `1`: HTTPS

Note:
- Before starting the server in HTTPS mode, you must configure the certificate and key file paths using `AT+WEBSERVERCFG`.
- To switch between HTTP and HTTPS, stop the server first (`AT+WEBSERVER=0`), reconfigure with `AT+WEBSERVERCFG`, then start again.
- If the server is already running, issuing `AT+WEBSERVER=1` again returns ERROR. Stop the server first.
