My OLED screen looks like a QR code. I have tried re-seating the cable multiple times but makes no difference. I have tried to run the CAT command you mention but it does not work. Please help?
The issue has been resolved. We recommend using the following commands to update the Pironman5 software again:
cd pironman5
git pull
sudo python3 install.py
After the update is successfully installed, please restart Pironman5 and check if its functions are working properly. If you still encounter issues, we suggest reinstalling the operating system and then reinstalling the Pironman5 software.
