I'm looking for simple presence detection. I'm on Windows and connected X4M300 via USB. I executed the presence_example.py from https://github.com/mvolstad/xethru-python-driver https://www.xethru.com/community/resources/xethru-python-driver.33/ changed it to my own COM port, but I just get 'Starting XeThru sensor... Reset module failed'. When I have XeThru Explorer running in parallel I get 'Starting XeThru sensor... Ready.', but nothing else. I'd expected a "Presence detected." message. It appears the sensor isn't initialized yet? sensor.is_initialized() returning false?
