In the case where the header starts with the following: For your application, assuming the HTTP Post function is written correctly, you should not need to worry about anything other than the XML to be sent to your device. In short there are about five layers of nested protocols. HTTP is a protocol based on top of TCP, which is based on top of IP which is based on top of Ethernet. Basically they are what make the HTTP Post call to the HTTP server running on the device you are talking to.Ĭontent-Type: application/x-www-form-urlencoded The following and other similar headers are the HTTP header, and not part of the XML. Rpc(returnAddr, “reportTempData”, loadNvParam(NV_DEVICE_NAME_ID), covnertData(tempData))Īt issue is just getting the thing signed up. Rpc(returnAddr, “reportTempData”, nodeName, tempData) ReturnAddr = rpcSourceAddr() # or can be defined or discovered – up to you You can add a lot to this if necessary, like reporting a node type/version, converting the data on the node, etc… Here the raw ADC value is reported back to the client for conversion. Here is an example (merely an example since I do not know how you will ultimately have your HW setup). The remote device (ie the one taking the measurements) simply requires you to define the function you want to call over the air. You do not need any additional software on the USB stick as it can route/forward rpcs without needing a script. SNAP connect takes care of connecting to the device on USB0 Srv.connectSerial(CONN_TYPE_USB,1) # USB0 is in fact the 1st Srv = ServerProxy(" allow_none=True) # The Python XMLRPCLib way to connect to the server

I want to be able to put this on my own URL and just call something like Not sure how to do that. as shown below.ĬONN_TYPE_USB = 2 # From the manual your LabVIEW code calls for another localhost. I know it HAS to be simple.įirst, have a script running called SNAP Connect that "listens" for commands issued from LabVIEW. Still trying to get the SYNAPSE system to work with LabVIEW.
