Luxonis-Lukasz

Hi tuantran
Did you install required dependencies and added udev rules in your Raspberry Pi OS?

You can find more info here and here how to set these up.

tuantran

Luxonis-Lukasz Thank you for your help ^_

tuantran

yes, I followed as link: "https://docs.luxonis.com/projects/api/en/latest/install/#raspberry-pi-os". But, I can't connect to device 🙁

erik

tuantran Is the error you have the same as this one? And do you use the original USB c cable?
Thanks, Erik

tuantran

erik Thank you for your reply. I'll check this issue

tuantran

erik I had tried it but error wasn't changed 🙁

RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'color' (X_LINK_ERROR)' I just got this error after setting up OAK-D-Wifi, kept the demo script running and it just crashed with no warning and this error. Should be up to date with the install_requirements.py, any help would be appreciated. Depthai version installed: 2.4.0.0

erik

Robgreen did you use the depthai_demo.py? what arguments did you use? We would love to investigate it further and fix any potential issues.
Thanks, Erik

tuantran

erik yeah, I'm customizing my project connect OAK-1 from RPI-v4 but not connect when I created pipeline for device

erik

Hello tuantran, could you share your pipeline (code)? From my understanding the original example code is working, but when you customize it's not working anymore?
Thanks, Erik

I have the same issue as @tuantran. Are there any solution for this?

erik

binhds this is a quite generic error. Could you share pipeline/blob that you are trying to run?

binhds

erik I try to run examples in depthai-python on Raspberry Pi4 and all of them display the same issue.

erik

sorry for the inconvenience binhds, have you followed the getting started/installation steps (which are also linked above in this discussion)?

binhds

Yes, I do. But I will check the installation again for sure. Thank you very much erik .
