Hello,

I did not receive this patch, as I was not on the CC list; I was not
aware of it. I will test it shortly.

Any guidelines how I should test this functionality? I have a Sony Xperia 10 i4113
mobile phone with LineageOS 19.1 / Android 12L, which according to the spec supports
Bluetooth 5.0. Quick Google search tells me that I should do things like 

        hcitool lescan

to discover the phone, then use gatttool to list the services, etc.

Greetings,

Mateusz
