Hi,

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

Hi @jdr, I’ve created this github ticket to track the bluetooth firmware update request and we’ll let you know once the next OS release becomes available in the dashboard.

Hi @jdr , the release v2.75.0+rev1 for the Pi4 includes the updated firmware file BCM4345C0.hcd.

@acostach thank you so much for the quick turn around! I’ve installed the updated OS and am testing now. Will report back if I find any issues - so far so good.
