Hi All,

I am getting the following error when trying to run a simple program to transfer a file between a Raspberry Pi running the C SDK version 2.0.2, and a thingworx server.

twFileManager_TransferFile: Error invoking Copy service on FileTransferSubsystem

Does anyone know what this error means or how I can solve it?

Thanks!

Are there any more errors in any of the logs?

Is it connecting to the platform, do you see anything about this in the platform/application log? Have you looked into the example provided with the CSDK package?

Unfortunately with the new SDK there is no example which includes file transfer. I am able to successfully connect to the platform. I have included the full output from the program when run, as you can see it is able to connect the websocket, initialize the api and build the virtual filesystem.

I've responded to your previous thread, there is an example suuplied with the new SDK. I'll copy here:

"

As of 2.0 there was a slight change in how the examples are provided. So, now there is a README_BUILDING.txt and CMakeLists.txt files , that along with the documentation, you may refer to to build your sample projects.The project SteamSensor will include all of the features enabled by default (again you may refer to the documentation to disable the ones you don't need)

File Transfer Example in CSDK?

The new SDK comes with the documentation within the downloadable

Page 111 and 112 talk about building the example using the CMakelist with all of the options enabled by default:

Hi Polina,

Thank you for pointing that out. I attempted to run cmake with the flags in order to build the applications, but when I added that I got the same errors as before. I also noticed on the server side in the logs on the mashup I see this error:

ERROR - Error in invoking service Things_repositoryThing, LoadText, Things, repositoryThing, Services, LoadText. Error from the server: "File Does Not Exist"

Hi Connor, I apologize I didn't notice this reply. Would it be possible to open a support ticket for this so we could dedicate a resource to investigate or would you like us to open one on your behalf?
