Hey Guys,

i tried to write a simple Programm to change the angle of my servo with the "pi gpiod" node on my Raspberry pi. In the debug window i just get the message: "Error:connect ECONNREFUSED 127.0.0.1:102". I hope there is any help for me.

Are you sure that you are using the right IP port? The default appears to be _8888_?

Port 102 is a privileged port number and you would have to run gpiod as root to have that.

But you are trying to connect to port 102 which is clearly wrong. Does the node have a setting for the port? I don't use it so I don't know.

There is a possibility to give the host. Ive got there "localhost" and "8888"

You have to run the pigpiod daemon in a separate terminal session

`sudo pigpiod`

The node will then connect to that running daemon and it will work (went thru same process myself 4 days ago ) 🙂

☹  
Is this a standard Pi running Raspbian?

Just noticed that your getting a strange port number - got this message before I fixed mine

I can get that error by running the command twice

Can you switch off and on again and try it again please?

restart your pi - dont run the sudo pigpiod command - run this instead and see what it gives

`sudo ps aux | grep pigpiod`

So that shows its already running - I wonder what is starting it?

But never mind - at least its running 🙂

So - if you start node-red - are you still getting the ECONNREFUSED localhost:102 error message?
