EMS on Raspberry Pi, error connecting

Hello, 

 

While trying to connect my Raspberry 3 B+ to Platform, i get this error when doing : sudo ./luaScriptResource  : 

 

 

[FORCE] 2020-09-26 14:10:45,205 ./luaScriptResource: Starting up ....

Myabe something wrong in my config ? 

 

config.lua

 

scripts.log_level = "INFO"
scripts.script_resource_ssl = false
scripts.script_resources_authenticate = false
scripts.PiThing = {
    file = "thing.lua",
    template = "PiTemplate",
    scanRate = 1000,
    taskRate = 30000
    }
scripts.rap_host = "127.0.0.1"
scripts.rap_port = 8080



scripts.data_security_key_hash="4vt6VnYj+93wOHypT0jFoIwvk93bsM3UA7n1WAS7FqQ"

 

 

config.json

 

{
        "ws_servers":   [{
                        "host": "pp-2009221255A9.devportal.ptc.io",

                }],

                "authenticate": false
        },

                "level": "INFO"
        },
        "certificates": {
                "validate": false,
                "disable_hostname_validation":  true
        }
}

 

 

I'm using Thingworx platform 9.0 Trial

What version of EMS are you using?

The latest version of EMS has changed to disallow default insecure behavior.

Try this config file that explicitly turns off security features:

 

scripts.log_level = "INFO"
scripts.script_resource_ssl = false
scripts.script_resource_authenticate = false
scripts.script_resource_host = "127.0.0.1"
scripts.script_resource_port = 8001
scripts.PiThing = {
file = "thing.lua",
template = "PiTemplate",
scanRate = 1000,
taskRate = 30000
}
scripts.rap_host = "127.0.0.1"
scripts.rap_port = 8080
scripts.rap_ssl = false
scripts.rap_server_authenticate = false

Does anyone have an idea ? 

Thank you

Thank you for your answer. 

I used your file, i had this error : 

 

[ERROR] 2020-10-01 12:33:38,698 luaConfigurator::initialize: Error while loading                                                                                                                                            file /home/pi/Desktop/microserver/etc/config.lua. msg: /home/pi/Desktop/microse                                                                                                                                           rver/etc/config.lua:5: malformed number near '127.0.0.1'

 

So i added some " ", it's going better and now i have this one :

Looks like there is still 2 errors, one in PiTemplate and the other one... i have no clue. 

I don't know which version of EMS i'm using, and don't know where to find this info (i did search)

 

Thank you for your fast answer. 

 

it's definitely better, but now i have this one :

Any idea ?

it looks like it's finally connected : 

 

pi_connected.png

 

But for some reasons, only the temperature gets updated, the 2 other metrics don't move, and the temperature stay at this value at all times, can't figure why...

The Raspberry Pi 4 changed some of the system calls to get physical properties of the board. Change this line:

s = string.match(s,"frequency%(45%)=(%d+)");

To this:

s = string.match(s,"frequency%(..%)=(%d+)");

Thank a lot, that worked !! 

I'm on Rasp 3B btw !
