    Error connecting Raspberry EMS to Thingworx Composer

    Hi,

    I just installed the EMS on my Raspberry Pi, following the steps in https://developer.thingworx.com/resources/guides/thingworx-raspberry-pi-quickstart/launch-ems I created a config.json file in order to bind it to my Thingworx composer running on another computer in my local network but I have some issues.

    Hi I am having the following errors in debug:

    terminate called without an active exception

     

    My config.json file is:

     

    {

        "ws_servers":   [{

                "host": "192.168.15.166",

                "port": 8080

            }],

        "resource": "Thingworx",

        "http_server":  {

            "host": "127.0.0.1",

            "port": 8080

        },

        "appKey":   "78e807c4-a1c0-458d-ace5-c465e16f3efb",

        "logger":   {

            "level":    "DEBUG"

        },

        "auto_bind":    [{

                "name": "PiThing",

                "gateway":  false

            }],

        "certificates": {

            "validate": false,

            "allow_self_signed":    true

        },

        "ws_connection":    {

            "encryption":   "none",

            "verbose":  true,

            "msg_timeout":  1000

        }

    }

     

    When I access my TW composer "ws_servers" on "192.168.15.166:8080/Thingworx", I login with an user and a password, Do I have to put these credentials somewhere in the config.json file? This could be the cause why the binding is not possible or has nothing to do?


    Thanks!
