Interestingly, the firmware (version...) shipped with Debian Sid is not in the official linux-firmware.git repository; its md5sum doesn't match any of prior versions of the file: > https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/intel/ibt-11-5.sfi Emmanuel, how can I determine the firmware version ("FW Build" and/or "Release Version") from a given file (e.g. ibt-11-5.sfi/.ddc)? > Regardless of the BT firmware version thing which is a pure Intel > problem, I have heard > about problems in the BT stack itself but I can't help about this. Though I've never really used the Bluetooth stack until this hardware, it seems the stack/blueman-* applications only behave oddly when there's problems with the firmware: never an issue when not using simultaneous 2.4 GHz WiFi + Bluetooth, or with this latest firmware, or approx. 2 years ago when I first started using this setup.
