Started having random Bluetooth disconnect problems w/RPI4 and bluetooth sensor. Resulted in orphan processes consuming 100% CPU. I patched BCM4345C0 a few days ago and have not experienced the problem since. It appears the patch contains a number of fixes for other issues w/the bluetooth firmware. Any chance to have this included in the next OS release?
I think the underlying problem is actually related to this issue, that’s also solved by the latest release: Bluetooth low energy data loss · Issue #1548 · raspberrypi/linux · GitHub
