AWR 4WD Smart Car Kit: errors

1697220204

Hi,

I followed the instructions in this tutorial:
https://www.adeept.com/video/static1/itemsfile/511343Tutorial.pdf

I downloaded the repo to my raspberry pi 4:
git clone https://github.com/adeept/Adeept_AWR.git

then I did: sudo python3 Adeept_AWR/setup.py

Then shutdown, connecting the camera and the HAT and reboot - but I can't open the web page http://192.168.x.xxx:5000/

Manually running
sudo python3 webServer.py
shows:
mpu6050 disconnected, ARM MODE ON
......................pause..........................

It may be caused by incompatibility between the Raspberry Pi image file and some dependent libraries.
Please download and burn Raspberry Pi OS (Legacy) according to the content "Method one" in the link below, then configure SSH and WiFi, download the product code and run the setup.py program.

I also have been struggling with this problem recently.
Indeed, only Raspberry Pi OS (Legacy) is capable to work without issues. But setup.py is not tuned to new versions of dependencies. To solve this, you can use the one from my fork here:
https://github.com/majki09/Adeept_AWR/tree/master

Don't forget to enable Legacy camera support with raspi-config.

Hope you will get this working like me!
