to do AoA, the device needs two antenna.. the DWM3001CDK only has 1 antenna.. so it can do distance, but not AoA.. a dual antenna device can provide AoA from the 3001CDK signal.
connecting to an MCU is different
the FIRA CLI/UCI support USB connections. currently connected thru a python script.
the QANI support (Apple Nearby) is signal receiver only and uses BLE from the phone to send the commands to start the ranging session with the Apple Ux chip in the phone. the 3001CDK board has the pin headers and can connect thru the raspberry pi header.. but neither of the current ranging SW work thru the header.
