Android version: 8.1.0
Phone: BQ Aquaris X Pro.
The phone ships with almost-stock Android. I am using Nova Launcher (not sure if important)
I have a Bluetooth headset on my motorbike's helmet wich supports both Bluetooth connection with the smartphone, and direct connection with another headset, but not simultaneously. So if I turn on my headset while my phone's Bluetooth is on, it connects automatically to my phone, before it connects to my partner's headset.
Until now, I was just fine disabling Bluetooth on my phone when needing to pair with another headset. But I just got an smartwatch, and every time I disable Bluetooth on my phone, when I enable it again, the watch connects to my phone and starts a painfully long a-gps updating process.
How do I tell my phone not to connect to the headset automatically?
