ThingWorx and Raspberry Pi Connectivity

[atsarev]

Hello!

I connect Raspberry Pi to the platform thingWorx 8.1.2 to get the temperature and humidity values.

I reached the "Connections" step (all other steps were successfully completed).

According to the instruction, a "temperature-thing-jar-with-dependencies.fire" file is created, which must be copied to raspberry Pi.

Then I prescribe the command  on the raspberry card:: java -jar ./temperature-thing-jar-with-dependencies.jar http://1XX.6X.3X.11X:8080/Thingworx 382fac73-e22e-435f-a44f-e74becc0a66d 2302 4 (Instead of X, normal numbers)

The result is an error:

02:48:26.096 [Client-EndpointMonitor-1] ERROR c.t.c.c.e.ClientCommunicationEndpoint - Refilling connections on [endpoint 0, uri: http://1XX.6X.3X.11X:8080/Thingworx] failed : timeout waiting for websocket handshake to complete

I ask you to help with the solution of the problem. logs and others in the attachment.

Andrey Tsarev​: For the connectivity issue, could you please confirm if the appkey used is part of Administrator group. If not, then please create a new key with Administrator ID and see if it help resolve the issue. Also, which OS is been used on Raspberry Pi  and do you see any network issue/firewall blocking tomcat port ?

Thanks for the answer. Yes, I connect as an administrator. And the key is set from the administrator account. On Raspberry Pi Linux is installed, and all ports are open.
