So, I downloaded the disk image yesterday for the Sphero SDK version of Raspberry Pi OS and it worked fine, letting me drive the car, use set_all_leds.py, etc on my Raspberry Pi 3B+. However, after I updated the operating system by typing sudo apt-get update and sudo apt-get upgrade, the Sphero Python scripts no longer work. However, there is no error message.
If I run set_all_leds.py, it will say “Checking RVR Firmware” and then return to command prompt without turning the lights red. The only difference from when it worked is that I ran the latest OS updates.
