Error trying to connect ThingWorx to the raspberry pi.

Hi. I joined this community just a few weeks ago because i'm currently working on a project among which basically consist on transfering some kind of information to a clud using a Raspberry pi device.

I'm currently dealing with the Quickstart tutorial, but i'm having next problems while trying to validate that my EMS has been succesfully connected:

            "port": 80

        }],

        "port": 8080

    },

    "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

    }

}

Could somebody help me please?, becase I need to go through this step in order to continue with the tutorial.

This thread might help

https://community.thingworx.com/thread/40338?q=ems%20l


I have found it pretty easy to use the SDK directly using a Raspberry PI and a Wifi adapter connected and running localThingworx server - this reduces problems with networks, certificates etc. so you can focus on the connection.

In the past I have set a PI and used the SDK to deploy the EMS code and used my phone as a hotspot so the Thingworx server and PI can connect to the same network over the same wifi. Once you have that then you can find out the ip for the server and set that to the correct values in your main.c.

Alternatively if the Server is hosted you will have get its ip address and plug that into you EMS settings. Hopefully the server is not using certificates and port 80 is open.

example of code in the main.c 

#define TW_HOST "192.168.43.154"

#define TW_APP_KEY "ce22e9e4-2834-419c-9656-ef9f844c784c"

#if defined NO_TLS

int16_t port = 80;

#else

int16_t port = 8443;

#endif

Hi,

we are facing the exact same probleme here. Problem is that we have to use WSEMS in order to use Software Deployment Plugin in Thingworx Utilities and can not go for the SDKs. Is there any solution for this problem?

We are using raspian with Raspi3 and Thingworx 8.0. Same configuration works on Windows or Linux WSEMS. Just the Linux-ARM-HWFPU is not working which we actually need for the Raspi.

Any help would be appriciated.

Kind regards,

Vincenzo
