ValueError - too many values to unpack

[jonovos]

I successfully mounted the Bluetooth, via a BT dongle on a Raspberry-Pi-3B+(plus), and connected just fine with the Sony PS4 controller. Everything was fine.

I walked away from the system for several hours, leaving the BT connection to idle.

When I came back, the BT-connection died, and a quick check showed an error in bluetooth.py . Apparently a split() function tried to create too many map's of BT devices. ((((-I work in a very busy development area, FULL of lots of BLE-advertising devices-))))

Below is a chunk of my terminal log.
After I "stop" the ds4drv service, I can "start" it and connect again.
