linux-firmware is missing intel/ibt-hw-37.8.10-fw-1.10.1.14.d.bseq and bluetooth isn't pairing devices

[slimbook]

Hello,
We have problems with the bluetooth of wifi card Intel 7265 N. The d bluetooth isn't pairing devices.

The driver is updated, we check checked kernel.org
But dsmeg shows not find the file bluetooth:

kernel: [ 12.428031] bluetooth hci0: Direct firmware load for intel/ibt-hw-37.8.10-fw-1.10.1.14.d.bseq failed with error -2
kernel: [ 12.428034] Bluetooth: hci0 failed to open Intel firmware file: intel/ibt-hw-37.8.10-fw-1.10.1.14.d.bseq(-2)

This is an Intel 7265 N card,this isn't AC, but this also has bluetooth, and Intel don't indicate compatibility with limitations (Intel does in other models):
http://ark.intel.com/es-es/products/84177/Intel-Dual-Band-Wireless-N-7265

We have tested the same hardware, and same Ubuntu installation, with the model wifi 7265 AC and bluetooth works, only not works with 7265 N, not pair devices.

Thanks

Status changed to 'Confirmed' because the bug affects multiple users.

Note that the driver has a fallback, after trying to load the file above it tries to load intel/ibt-hw-37.8.bseq which is present, so the driver does have firmware. I don't know whether there's another version which is better, but if so it's not something that Intel has released to the linux-firmware project.

This is just to say that though the problem may be a firmware bug, the problem isn't that the device fails to load any firmware at all.

Hello,
We have tested several versions and none to work.

The bug is still there in a new installation of Ubuntu Desktop 18.10 two years on from the original report...
