Question

I'v got the following JSON request to retrieve the serial number of the connected device. 

http://192.168.1.1/ubus

{

    "jsonrpc": "2.0", "id": 1, "method": "call", "params":

    [

        "91beb9b2a4b0b525ef7f673d1ff5bf53", "file", "exec",

        {

            "command":"mnf_info", "params":["-s"]

        }

    ]

}

This works great on a RUT955 (version RUT9_R_00.07.02.4), but I receive a result 6 error for the RUT300 (version RUT30X_R_00.07.00).

{

    "jsonrpc": "2.0",

    "id": 1,

    "result": [

        6

    ]

}

Thanks in advance!

Answer 1

This is because JSON-RPC was not implemented in RUTOS 7.0. It appeared only with RUTOS 7.2. Upgrading to the latest firmware version:

I have 7.2 and the error still exists.
