Hello Guys! I just started to use Raspberry OS Full with applications. First when I installed it, noticed, that it has built in Node-RED (so cool). I tried it without any modification and I manage to control GPIO pin 2 without any issue through Node-RED. Then I did an upgrade according to this arti…

[image] tiby007: I setup PIGPIOD to start automatically after reboot with this command: sudo systemctl enable pigpiod maybe this service that you are starting uses the PINS and doesnt allow the Node-red RPi Node to access them ? what if you stop that service and restart NR server ?

[image] tiby007: I setup PIGPIOD You don't need pigpiod for node-red-node-pi-gpio. That is for node-red-node-pi-gpiod. See Interacting with Raspberry Pi GPIO : Node-RED I don't know what the effect of running pigpiod is when trying to use the pi-gpio node.

This is not about creating custom nodes - moved to general

Hello! I need to have run this service to be able to control the robot from my python program. Anyway, I just tried to stop the pigpiod to check if that is the case, then restarted Node-RED several times, but the results was the same: not available.

Hi Colin! When I tried this on the brand new Rasberry OS, it worked. I could start the robot sequence from a button connected to the GPIO and also from Node-RED. At that time PIGPIOD was running behind. So I think that is not the problem. Something else should be. Any other idea?

[image] tiby007: The newest Rasberry OS is installed on it. Which version is that? [Edit] Also what do these commands show apt-cache policy rpi.gpio groups

I don't think it will help, but for the record, what does uname -a show?

That all looks ok.
This thread has another user unable to access the GPIO with raspbian bullseye (which has only just been released)
