Volla Phone 22 / Gigaset GS5 does not recognize Amazfit GTR/GTR2

[chris_bavaria]

UT 20.04(OTA-4) can pair to BT speakers, but Amazfit GTR/GTR2 cannot be found.
Restarting the clock and phone several times doesn't help.
Could it be that drivers for this phone are incomplete?
Bus: Virtual indicates that the device is virtual, which is unusual for physical Bluetooth hardware?

Pairing with Amazfish in UT 20.04(OTA-4) on my GooglePixel 3a works.
Has anyone had the same experiences?

@chris_bavaria I have the same problem. I think it might be bluetooth le which is not supported. I tried to bring it up in the volla telegram group, but noone responded...

Hi there,

I also have the problem, that my Amazfit GTS is not found by bluetooth on my Volla 22 with 20.04 OTA-5.

@magnargj: Do you have any news on this topic?

Is there an issue opened in gitlab to bring it up to the devs, yet? I haven't found one...

I am willing to test and help as much as I can, if needed.

Best regards,
zintor

Addendum:

I found an issue at github "HelloVolla"
https://github.com/HelloVolla/ubuntu-touch-beta-tests/issues/129
Please also comment or vote for it.

I am asking me, if it is a hardware or software problem?
How can we narrow the problem to help the dev to solve this issue?
Unfortunately I am not a dev, but have no problem to import a fix and play with it to get it fixed.

Best regards,
zintor
