Bluetooth, BlueGiga, Airthings Wave Plus issue

Add-ons Bindings

Hi,

I’ve some issues with the generic bluetooth binding with OH 2.5.11. I have a Windows setup, and using BlueGiga. I’ve added Airthings Wave Plus. This works to begin with but stops to work after a while. I see that the item receives more updates than the refreshinterval (600). Why, can it be related to that somehow?

See this screenshot from Grafana:

This is the only related error I can see in the log:

This is my Bluetooth dongle thing:
Bridge bluetooth:bluegiga:adapter1 [ port="COM3", backgroundDiscovery=false ]

This is my Airthings thing:
bluetooth:airthings_wave_plus:adapter1:sensor1 "Airthings Wave Plus Sensor 1" (bluetooth:bluegiga:adapter1) [ address="...", refreshInterval=600 ]

I’ve tried to clear cache, reinstall, create new thing… but same problem and same error in the logfile. Anyone any ideas? Maybe I should create a binding bugreport at github?
