Now that you have obtained a Session ID, you can issue commands to the router. Lets start with commands that return information about the router. For example, this is a command that returns the router's '''[[RSSI]]'''(signal strength) value:
Now that you have obtained a Session ID, you can issue commands to the router. Lets start with commands that return information about the router. For example, this is a command that returns the router's '''[[RSSI]]'''(signal strength) value:
{
"jsonrpc": "2.0", "id": 1, "method": "call", "params":
[
"<span style=color:red>bde01a2da4a6f4a515bb9466f90bc58a</span>", "file", "exec",
{
"command":"<span style=color:orange>gsmctl</span>",
"params":["<span style=color:orange>-q</span>"]
}
]
}
The section highlighted in red is your Session ID, and the sections highlighted in orange are the command and the parameter. In this example we're using a '''gsmctl -q''' SSH command that returns the router's '''[[RSSI]]''' value:

The Response '''{"jsonrpc":"2.0","id":1,"result":[0,{"code":0,"stdout":"<span style="color:green">-59</span>\n"}]}''' tells us that the router's current signal strength is <span style="color:green">-59 dBm </span>.
The Response '''{"jsonrpc":"2.0","id":1,"result":[0,{"code":0,"stdout":"<span style="color:green">-59</span>\n"}]}''' tells us that the router's current signal strength is <span style="color:green">-59 dBm </span>.
You can issue almost any SSH command in a similar manner. For example, you wish to check the '''network''' config file. The SSH command to do so would be '''cat /etc/config/network''', which, translated to JSON-RPC, would be:

{
"command": "<span style="color:orange">cat</span>",
"params":
[
"<span style="color:orange">/etc/config/network</span>"
]
}
]
}
The command and the parameter are highlighted in orange. In this case the Linux '''cat'''(short for “concatenate“) is used to view the contents of the '''/etc/config/network''' file. The Response is:
