Just received the A111 sensor and I'm not sure if it is functioning properly. The Gui/ will not connect to the sensor. When I run the diagnostic program I get this:

The A111 Pulsed Radar only works with Raspberry Pi 3's and 4's as stated in the hookup guide. Can you confirm that you're using one of these versions?
