Running post_to_influxdb.py for a long period creates hundreds of zombie hcitool processes about ruuvitag-sensor

There must be something wrong with killing hcitool process
https://github.com/ttu/ruuvitag-sensor/blob/master/ruuvitag_sensor/ble_communication.py#L90

Any ideas?

[zbrozek]

Possibly? But how would I find out? It doesn't look like errors are propagated anywhere. Maybe the stored PID is wrong?

Will make a fix for hcitool process killing

Fixed hcitool subprocess closing (5deed32).

Also updated the https://github.com/ttu/ruuvitag-sensor/blob/master/examples/post_to_influxdb.py code. For long running processes should use RuuvitagSensors.get_datas-method as it won't start a new BLE scanning subprocess with each method call.
