I have been trying to connect the drum sensors to my phone for a while and it doesn’t work. The Android version is 8.1. Bluetooth recognized them, but the app doesn’t. Both, BETA Freedrum and Sensorware don’t seem to recognize it.
Were they ever able to successfully connect?
Have you tried removing the sensors Bluetooth information from your device and restarting it?
Try also deleting the apps and redownloading them as well.
Make sure to allow location settings for a bluetooth connection. We do not track your location it is just a Android permission.
