Hello,
I have a bt 4.2 mouse that has a battery service, but no battery
attribute visible in Bluez, Rapoo m550 using YiChip 1201.
Is it even hypothetically possible that a device can have a battery
service, but no battery attribute?
This is what I see in my syslog

bluez filters it out. This is exactly what I am seeing.
