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:

I receive the following error:

(sphero-sdk-raspberrypi-python) pi@raspberrypi:~/sphero-sdk-raspberrypi-python/projects/keyboard_control $ python
Checking RVR firmware versions…
Traceback (most recent call last):

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.


Support do you have any guidance?

I am unable to run even a simple without getting this error.

I assume the firmware is latest, and pi environment appears to have what is required.


Hi @mdp,

This is an issue we are looking at, we should know more later this month.
In the meantime, you are welcome to modify the SDK. You can track down the error, and disable the call to the function that is triggering the problem.

In home/pi/sphero-sdk-raspberrypi-python/sphero_sdk/asyncio/client/firmware/, you can disable the calls to the FW version checks, and the print statement associated with them.

I hope this helps,


Hi many Thanks for the response I will use the workaround.


Hi, just to confirm removing the calls to the FW Check worked.

Thanks again for the pointers.
