Comment 6 for bug 1824559

Hello Daniel,
Thank you for your answer!
OK for kernel assignment...to be honest, I was not sure where to assign it :)

Let me share last tests I did:
- upgrade to Bluez 5.50 (previously 5.48) (I added the bluez ppa and apt update / upgrade. then disconnect the mouse, re-pair it) => same situation.
- I paired with my work laptop (win7) : it works perfectly in Bluetooth.
- I tried different places (2 places at home, and now a third one at work) => works fine on my work laptop win7; not on my XPS with ubuntu.

I have read the bug 1746164 you mentioned, but:
- I tried 2 ubuntu laptop and my XPS13 9370 is based on ath10k (not ath9k) ? (I'm not sure for the other laptop). Is this bug applicable to ath10k ?
- I also tried a Sabrent bluetooth 4.0 usb stick...this one is based on CSR chip => issue is still there (with ~20Hz polling while it's 22Hz with internal bluetooth)
- I can still anyway try to check this issue from bug 1746164: do you think I can check it by turning OFF the wifi and test my mouse again ?
