Running LSR on Raspberry Pi

Hi,

 

I'm trying to set up my Raspberry Pi to Thingworx. I'm following the quickstart guide (https://developer.thingworx.com/resources/guides/thingworx-raspberry-pi-quickstart/run-lsr). I've set up the EMS and that works. However, I'm now at the point where I have configured the LSR and am now trying to run it. I have the EMS running in another window and input the code below as instructed:

sudo ./luaScriptResource

The result is below:

[INFO ] 2018-03-29 13:50:57,437 ./luaScriptResource: Using config file: /home/pi/microserver/etc/config.lua
[FORCE] 2018-03-29 13:50:57,437 ./luaScriptResource: Starting up ....

Any advice is greatly appreciated.

 

Thanks in advance,

Hello cssummers1,

 

I made some quick changes to the lua file.Try with the below config.lua

 

scripts.log_level = "DEBUG"
scripts.PiThing = {
                file = "thing.lua",
                template = "PiTemplate",
    identifier = "PiThing",
                scanrate = 1000,
                taskrate = 30000
        }

scripts.rap_host = "127.0.0.1"
scripts.rap_port = 8000
scripts.rap_ssl = false
scripts.rap_server_authenticate = false


scripts.script_resource_host = "127.0.0.1"
scripts.script_resource_port = 8001
scripts.script_resource_ssl = false
scripts.script_resource_authenticate = false

 

 Changed the scripts.rap_port to 8000 - This should be the port on which EMS is running. Should be the same as the http_server port in config.json.

 

I have also added the identifier in the binding section.

 

Let me know if this helps.

Hi,

 

What version of EMS are you using? And can you share your config.lua file here?

I'm using the latest version of the EMS that's provided by ThingWorx - I got the download here.

This is the current state of my config.lua file:

scripts.log_level = "INFO"
scripts.PiThing = {
 file = "thing.lua",
 template = "PiTemplate",
 scanRate = 1000,
 taskRate = 30000,
 indentifier = "PiThing"
 }

scripts.rap_host = "127.0.0.1"
scripts.rap_host = 8080
scripts.rap_ssl = false


scripts.script_resource_host = "localhost"
scripts.script_resource_port = 9001
scripts.script_resource_ssl = "false"
scripts.script_resource_authenticate = false

 

 

Since making the post I made some changes to my config.lua file and this is the new output I get:

Hello Charlotte,

 

I noticed that you are using scripts.rap_host = 8080 instead of scripts.rap_port = 8080 in the config.lua.

Also as you have defined an identifier for the remote thing in the config.lua have you also added the identifier to the PiThing in the Composer?
