My Lenovo T530 Bluetooth does not work like so many others that have been reported. I am running Ubuntu 14.04.3 LTS 64 bits, kernel 4.4.0-75-generic, Broadcom Bluetooth BCM20702A1 (001.002.014) build 0000, Latest BIOS: LENOVO 2359CTO/2359CTO, BIOS G4ETA7WW (2.67 ) 08/24/2016
My dmesg error is: bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-21e6.hcd failed with error -2 Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-21e6.hcd not found My list of files in /lib/firmware/brcm is: bcm4329-fullmac-4.bin brcmfmac43242a.bin brcmfmac4350-pcie.bin bcm43xx-0.fw brcmfmac4329-sdio.bin brcmfmac4354-sdio.bin bcm43xx_hdr-0.fw brcmfmac4330-sdio.bin brcmfmac43569.bin brcmfmac43143.bin brcmfmac43340-sdio.bin brcmfmac4356-pcie.bin brcmfmac43143-sdio.bin* brcmfmac4334-sdio.bin brcmfmac43570-pcie.bin brcmfmac43236b.bin brcmfmac4335-sdio.bin brcmfmac43602-pcie.ap.bin brcmfmac43241b0-sdio.bin brcmfmac43362-sdio.bin brcmfmac43602-pcie.bin brcmfmac43241b4-sdio.bin brcmfmac4339-sdio.bin brcmfmac4366b-pcie.bin brcmfmac43241b5-sdio.bin brcmfmac43455-sdio.bin brcmfmac4371-pcie.bin Notice there is no *.hcd file... or anything for a 20702* Note that I do NOT have blueman installed. I am unable to pair with a mobile phone. The dmesg log repeats the firmware loading error every time I attempt to use the Gnome Bluetooth desktop utility. I have spent a lot of time chasing posts on related Broadcom bluetooth errors here and elsewhere without success. My bluetooth has not be operational for a VERY long time! When will we get a fix for this? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1065400 Title: Support for loading Broadcom bluetooth firmware Status in linux package in Ubuntu: Fix Released Status in linux source package in Precise: Fix Released Status in linux source package in Quantal: Fix Released Status in linux source package in Raring: Fix Released Status in linux source package in Saucy: Fix Released Status in linux source package in Trusty: Confirmed Bug description: Broadcom bluetooth chips require a tool called patchram uploader [1] to load firmware. This applies to at least BCM20702 and BCM43142. Although some of the devices have an OTPROM that contains required firmware, but it is found that these devices would not have HFP/HSP support unless a upgraded firmware is loaded via patchram uploader. This tool requires hci device to do the firmware loading, but this may cause some race condition between patchram tool and bluetoothd or something that also works on hci interface. Also it needs some hooks to make firmware loads after bootup, s3, s4, rfkill, and device hotplug events. Implement this loader in kernel module would make things more easier.
