Package: firmware-iwlwifi Version: 20161130-2 The ibt-11-5.ddc file format is broken. Therefore bluetooth isn't working as expected with Intel Bluetooth 8260/8265 chips.
When bluetooth service loading the firmware there are strange infos logged: > kernel: Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014 ... > kernel: Bluetooth: hci0: Minimum firmware build 1 week 10 2014 ... > kernel: Bluetooth: hci0: Failed to send Intel_Write_DDC (-22) A patch for DDC file is available: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/ commit/intel/ibt-11-5.ddc?id=581f24500138f5e410d51ab63b205be9a52f4c77 After replacing DDC file the log looks better: > kernel: Bluetooth: hci0: Firmware revision 0.0 build 95 week 37 2016 ... Please fix the package for Stretch.
