Note that I've found dozens of posts on the web that describe the same symptom, and a subset of those arrive at the same conclusion of this bug. I do agree that the license that the github repo holds indicates that the files are made available for personal use, but perhaps we can address that.
For my information, what licenses cover the firmware files we are shipping today in the brcm/ subdirectory that linux-firmware currently installs? Namely: bcm4329-fullmac-4.bin bcm43xx-0.fw bcm43xx_hdr-0.fw brcmfmac43143.bin brcmfmac43143-sdio.bin brcmfmac43236b.bin brcmfmac43241b0-sdio.bin brcmfmac43241b4-sdio.bin brcmfmac43241b5-sdio.bin brcmfmac43242a.bin brcmfmac4329-sdio.bin brcmfmac4330-sdio.bin brcmfmac43340-sdio.bin brcmfmac4334-sdio.bin brcmfmac4335-sdio.bin brcmfmac43362-sdio.bin brcmfmac4339-sdio.bin brcmfmac43430a0-sdio.bin brcmfmac43430-sdio.bin brcmfmac43455-sdio.bin brcmfmac4350c2-pcie.bin brcmfmac4350-pcie.bin brcmfmac4354-sdio.bin brcmfmac43569.bin brcmfmac4356-pcie.bin brcmfmac4356-sdio.bin brcmfmac43570-pcie.bin brcmfmac4358-pcie.bin brcmfmac43602-pcie.ap.bin brcmfmac43602-pcie.bin brcmfmac4366b-pcie.bin brcmfmac4366c-pcie.bin brcmfmac4371-pcie.bin brcmfmac4373.bin brcmfmac4373-sdio.bin -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1859223 Title: Firmware missing for Thinkpad X-series Bluetooth adapters, heads to headset HSP/HFP profiles not working Status in linux-firmware package in Ubuntu: New Bug description: Hello there, it's my third or fourth session spending hours trying to debug why a Bluetooth headset would not work in HSP/HFP mode on my x230. The failure more is super obscure because at the time of error the only thing you notice is that no audio comes through in either direction. Using the a2dp_sink profile works fine. The root cause for the problem is simply missing firmware, which dmesg hints at during bootup: Jan 7 04:11:12.809444 barbudinho kernel: [490029.978724] Bluetooth: hci0: BCM: chip id 63 Jan 7 04:11:12.809460 barbudinho kernel: [490029.979639] Bluetooth: hci0: BCM: features 0x07 Jan 7 04:11:12.825406 barbudinho kernel: [490029.995655] Bluetooth: hci0: BCM20702A Jan 7 04:11:12.829543 barbudinho kernel: [490029.996649] Bluetooth: hci0: BCM20702A1 (001.002.014) build 0000 Jan 7 04:11:12.829560 barbudinho kernel: [490029.996671] bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-21e6.hcd failed with error -2 Jan 7 04:11:12.829566 barbudinho kernel: [490029.996673] Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-21e6.hcd not found There are at least two firmware packages missing for different common X-series adapters; this is referred to from https://plugable.com/2014/06/23/plugable-usb-bluetooth-adapter-solving-hfphsp-profile-issues-on-linux and also https://wiki.gentoo.org/wiki/Lenovo_Thinkpad_T430.
