IoT & Connectivity

I am experiencing the same issue, was there any solution for this?

Hi, I have successfully create a ssh-connection and a vnc-connection over a edge device to an rpi via EMS. Now I try the same with RDP but this will not work. I have installed xrdp on the rpi (tcp-port 3389). I have setup the firewall of the edge device (where the EMS is running) to allow TCP 3389. When I try to connect via remote access widget I get the error message [ERROR] 2019-12-04 12:11:18,313 SDK: twTunnelManager_TaskerFunction: Error connecting to 1.0.1.2:3389. tid: 75da34af-e679-4338-984b-d2ec35f8818a. Error: 111 on EMS-side.

Hi All, I need a litle help. I would like to solve that, you don't have to sign in every time, it goes automatically log in to user. So i would like to create a Mashup access without login. I tried with Mashup parameter: USER, and PASSWORD, but no success. It will also be asked to sign in. I tried with Application Key, x-thingworx-session=true, but the result is: you mustn't log in, but it goes with error. Am I missing something? Can someone help me? Thank you, Ilona

  Hello, everyone!   With the release of ThingWorx 8.5, we’ve incorporated a lot of new functionality into our manufacturing and service apps. To cover a few, I’ve included the list below. We created a manufacturing common layer extension to bundle all the PTC-offered IoT apps (Operator Advisor, Asset Advisor, Production KPIs and Controls Advisor) into one extension to enable you to use them even more quickly. We added a UI to Operator Advisor to strengthen your development of work instructions. We introduced new shift and crew data models and user interfaces to standardize how to track workers’ shifts and crew availability. We also introduced Flexible KPIs to help you more rapidly develop apps to calculate common metrics. We enhanced the Operator Advisor MPMLink connector to allow users to access navigation criteria for filtering parameters based on required criteria with support for standard processes. We incorporated multiple context supports for assets—like different bu

At the moment I trie to use Thingworx 8.5 + Manufacturing Apps + KEPServerEX 6.7   I want to publish MQTT Messages Thingworx with the KEPServer and the MQTT Driver (Not MQTT Extension).   I successfully subscribe the Data in Thingworx. I created the Tags in KEP and I see the messages from a MQTT Client (Node-Red) via the MQTT Broker (Mosquitto) to the KEPServer. In Thingworx I created with Discover the Thing (Remote Thing) with the Binding to the KEPServer Tag. Everything works fine and I see the Value in the Properties.   But if I trie to change the value in the properties i see in the event log from KEPServer: Warning MQTT Client Channel2.Device1 | Unable to write to address on device. | Address = 'thingworx+invalue'. In KEP the Client Access = Read/Write. if change it to Read only I get an error in Thingworx.   In the MQTT Manual I found: Reading data from a MQTT server (writes are currently not supported)   Bu

Recently a customer from the ThingWorx Academic Program sent in a sample program they were having problems with. They were trying to post data from a Raspberry PI using Python to their ThingWorx server. It turns out that their program did work just fine and was also a great example of posting data from a PI using REST.Here is how to set up this example.1. Import the attached "Things_TempAndHumidityThing.xml" entity file.2. from the PI run 'sudo pip install requests'3. from the PI run 'sudo pip install logging'4. from the PI run 'sudo pip install http_client'5. Create a python file call test.py that contains this example code:#!/usr/bin/pythonimport requestsimport jsonimport loggingimport sys# These two lines enable debugging at httplib level (requests->urllib3->http.client)# You will see the REQUEST, including HEADERS and DATA, and RESPONSE with HEADERS but without DATA.# The only thing missing will be the response.body which is not logged.try:    import http.clien

Hey Everyone,   I am using ThingWorx v 8.5.0 and am having trouble increasing the font size of a drop down list . I am using the 'DropDown' widget, and have changed the 'item-value' font-size style property to 20px.     However, this seems to only make the 'hint text' in the drop down list larger, but when I expand the drop down, all the values are still a smaller font size.     Am I missing something basic here? How can I increase the font-size of the selection items in the new drop down widget? Thanks so much for your help!   Andrew

Hi,    I'm running the c-sdk 2-2-3-1545  in a device and when I try to download a file from the Thingworx repository to the device, by using twFileManager_GetFile(), I receive the following error:    [ERROR] 2019-12-03 15:09:59,666: twMessaging::handleMessage: Response ID 20 has code 160: Entity FileTransferSubsystem does not exist or is not yet associated with a Thing [ERROR] 2019-12-03 15:09:59,666: twFileManager_TransferFile: Error invoking Copy service on FileTransferSubsystem   I tried to call the Subsystems["FileTransferSubsystem"].Copy() service (In the Thingworx side) to validate the parameters that I was using, and everything worked fine. Can anybody help me with that ? Did you faced that error before? Thanks in advance. 

Hello Everyone,   I would like to extend an existing FileRepository Thing with links to directories in the same network as the Thingworx server.    When simply copying the Links into the FileRepository (on the Thingworx server, not the composer view), the content of these directory links is not traversed when running e.g "BrowseDirectory" service of the Repository.   Is there a way to also access the content of these links? The reason is that we have some projects distributed in the network and the files of these projects should be accessed via a Thingworx Thing (preferably fileRepositoryThing)   Any suggestions are appreciated very much!   Best Regards, Dominik
