Changes

Before anything else, you'll need to make sure JSON-RPC is enabled on your router. JSON-RPC is enabled by default, so if you haven't made any changes to the router's access settings, everything should be in order. Otherwise you can check JSON-RPC status by logging into your router's WebUI and navigating to '''System → Administration → Access Control'''. Look for the ''WebUI'' section; there will be an '''Enable JSON RPC''' field. Make sure it is checked:

The test highlighted in red is your Session ID, and highlighted in orange are the command and the parameter. In this example we're using a '''gsmctl -q''' command that returns the router's RSSI (signal strength) value.

Look for '''stdout''' in the post response: <span style="color:green">'''"stdout":"-73\n'''</span>". This tells us that the router's current signal strength is <span style="color:green">'''-73 dBm'''</span>.

Look for '''stdout''' in the post response: <span style="color:green">'''"stdout":"-69\n'''</span>". This tells us that the router's current signal strength is <span style="color:green">'''-69 dBm'''</span>.

The picture bellow is a visual representation of this example. Encapsulated in a blue rectangle is the answer to the ''gsmctl -q'' query: '''-73 dBm'''.
