Being relatively new to the RVR and Raspberry PI , I am attempting to run some of the projects once I have gone through the guidance Method 1.
I have set up the connection between the PI and the RVR according to the guidance (and double checked).
When I run: drive_with_wasd_keys.py
I receive the following error:
(sphero-sdk-raspberrypi-python) pi@raspberrypi:~/sphero-sdk-raspberrypi-python/projects/keyboard_control $ python drive_with_wasd_keys.py
Checking RVR firmware versions…

There are some are some other programs under Getting Started that work , like changing the LEDs, however a number fail with the same error above.
