Then the controller will re-load the FW patch. And you will find Bluetooth: hci0: read Intel version: 3707100180012d0da1 Bluetooth: hci0: Intel device is already patched. patch num: a1 Ethan -----Original Message----- From: linux-bluetooth-owner@vger.kernel.org [mailto:linux-bluetooth-owner@vger.kernel.org] On Behalf Of Mark Haun Sent: Wednesday, August 26, 2015 12:53 AM To: Ge, Ethan Cc: linux-bluetooth@vger.kernel.org Subject: Re: Intel 7260 spontaneous USB disconnect/reconnect every 23h18m07s Hi Ethan, Ge, Ethan [ethan.ge@intel.com] wrote: > Your Intel FW version hci0: read Intel version: 3707100180012d0d06, > it's too old. Please try latest Intel WP2 FW > Ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq in linux-firmware/intel. So I tried this before going away for the weekend, rebooted, and then checked dmesg when I got back. The issue is still there, spontaneous disconnect/reconnect every 23h18m07s like clockwork. I am starting to second-guess myself a little, though, because I am confused about the firmware naming. The firmware or microcode files I am familiar with (iwlwifi for instance) have the firmware version as part of the file name. The ibt-hw-* firmwares, on the other hand, appear to keep the *same* filename when new versions come out; only the increased file size indicates that the contents have changed. So I am guessing that the filename refers to the hardware revision it is intended for, rather than the firmware/microcode revision? Either that, or debian is not distributing the same firmware files as the ones in git! In any case, the dmesg output with the [presumed correct] firmware is precisely the same as before: Bluetooth: hci0: read Intel version: 3707100180012d0d06 Bluetooth: hci0: Intel device is already patched. patch num: 06 The size of the file "ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq" is now 17310 bytes. That is larger than the one it overwrote, but I didn't write down the old size. Kernel version is 4.2.0-rc4.
