BLE devices disconnect when the device enters sleep mode. Noticed this with a PineTime device. When the phone screen stays on (e.g. when the phone is charging) the connection is rock-solid. When the phone enters sleep, though, the connection drops.
I’ve of course tried to set the suspend policy with
mcetool. While this reduces the frequency of the disconnects, it doesn’t solve the issue entirely. Somehow, something is powered down that shouldn’t be.
- Connect a BLE device
- Turn off the screen
- Wait a few minutes
The connection is stable and is not interrupted
The connection is dropped
