My bluetooth fails with
bluetooth hci0: Direct firmware load for brcm/BCM4354A2-13d3-3485.hcd failed with error -2
The missing firmware file is not available here, so I assume it is correct to open a new issue for this.

The chip is installed in a Wortmann / terra mobile 360-11 netbook. Windows drivers can be downloaded from this page:
https://www.wortmann.de/de-de/systeminformation/R5105360.aspx
(in German; look for the item "Terra Mobile 360-11 Bluetooth Treiber")
However, there seems to be no .hex file, only some .bin files. Any hint on how to convert them to .hcd for use with linux (and for inclusion in this repository)?

Just out of curiosity, i tried renaming the firmware file BCM4356A2-13d3-3485.hcd to BCM4354A2-13d3-3485.hcd and rebooted.
Now the firmware loads (no error messages) and I can still scan for new devices, but I can no longer complete the pairing process or connect to any device, whether previously paired or not.

Hello.

First of all, firmware from this repository will not work with your device, it's total different chipset family.
But, as I can see, *.bin files are already in hcd format. Question is which of them can be for your device.
Can you please dump output from lsusb command?

EDIT: and lspci -nn too.

Thank you for the quick reply. Please find below the output of the lsusb and lspci commands. I guess the actual bluetooth device is part of the Broadcom wifi chip (last line).
There is a file called 4356a2rtecdc.bin, but my kernel actually asks for BCM4354A2-13d3-3485.hcd, see above. There is no file named 4354*.bin.

That's weird. You have "ID 13d3:3485 IMC Networks" that threats as BCM4354A2, but it should be BCM4356A2. lspci shows too that there should be BCM4356. Can you please post output of these commands:

  • dmesg
  • lspci -nnvv | grep -A12 Broadcom
  • hciconfig -a

This is the full output of dmesg: https://pastebin.com/SES6sMyS
Note: After booting, I tried to connect a bluetooth presentation remote to the computer using blueman.

As far as I can tell, this is only the wifi (802.11) device, not the bluetooth device.

Well, here what I found. BCM4354A2 is actually BCM4356A2. It seems in Linux Kernel typo or bug.
So, let's try again to rename BCM4356A2-13d3-3485.hcd to BCM4354A2-13d3-3485.hcd, reboot and again dmesg and hciconfig -a

Ok. Did that. No more error messages during startup. But connections still did not work.

Now comes the good part: After consulting the linux wireless pages at https://wireless.wiki.kernel.org/en/users/drivers/brcm80211 (which are acutally about the corresponding wifi 802.11 device), I learned that in addition to the fireware some EFI NVRAM information may be required for this device. Following the instructions from that source, I executed the following commands as root:

mount -t efivarfs none /sys/firmware/efi/efivars
cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcmfmac4356-pcie.txt

Notice the .txt extenstion vs. the .bin extension of the wifi firmware file.

Now after another reboot everything works as expected (currently tested with the presentation remoate and different bluetooth speakers: HSP and A2DP).
Awesome!
