RPI 3 - RVR issues (not responding)

Hi there,

I have a Raspberry PI 3+ set up and connected to the Sphero RVR as per the available instructions / SDK and using Python. My issue is that commands from the PI to the RVR will sometimes work and sometimes nothing seems to get through.

Here is an example:

Power on the RPI and RVR
python get_battery_state.py -> Works I see an output from the RVR
python get_battery_state.py -> Works, I see an output from the RVR
python get_battery_state.py -> No response
After this it doesn’t start working again

The same happens if I try e.g. setting the LEDs - sometimes it will work and then sometimes nothing happens and then it will only work again if I power on both devices (the PI is powered from the RVR)

Any ideas?

Many thanks

Matthew

might be good to double check your serial wires / connection between Pi and RVR
