By following the tutorial steps, the output in Raspberry Pi3b+ with Rasbian latest is the following:

sudo python2 read_waveplus.py 2930034778 10

After a reboot, a night rest and powering off bluetooth agents I managed to get one reading. But never received a second one, as error would appear.

sudo bluetoothctl power off power on agent off agent on scan off scan on

After which: sudo python read_waveplus.py 2930034778 60

There seems to be inconsistency and alot of unstability on the connection. The distance is not a factor here, as it works the same from 5cm to 10m.

Sometimes the sensor is able to connect and provide its information, but it never lasts longer than few readings. Then it fails for n amount of times and continues with successful reading.

It appears that this issue might be related. https://github.com/Airthings/waveplus-reader/issues/14

Can't say I solved it, but I managed to get it to work and with rather stable output by using another code, from https://github.com/hpeyerl/airthingswave-mqtt. The root cause is still unknown, It could have had the Wave Plus device connected to mobile app which might have interfered on something. But either way, now I am collecting data through a set container as MQTT messages.
