hi. from the many previous posts I was able to decipher the procedure to use: 1) find in the windows driver .inf the hex file to use and convert 2) get and compile and use hex2hcd to convert file to firmware 3) place the file in /lib/firmware/bcrm/BCM43142A0-0a5c-21d7.hcd
and get in my /var/log/syslog, the line that says that the firmware is loaded Nov 9 20:24:19 callisto kernel: [ 23.061550] Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=00b0 lmp_ver=06 lmp_subver=210b until I found out some weeks later than, the firmware is not always loaded when I boot, I don't know why. there is no error in the log but the firmware is not loaded. If I close the lid and reopen it to hibernate and wake-up then the firmware is finally loaded ! but then I found out the lines Nov 18 17:04:45 callisto kernel: [ 1769.978201] CPU: 0 PID: 5317 Comm: kworker/u17:0 Tainted: P OE 3.16.0-24-generic #32-Ubuntu Nov 18 17:04:45 callisto kernel: [ 1769.978202] Hardware name: Dell Inc.

Is it crashing because it tries to reload the firmware whereas it has already been loaded ? I got that dump stack before installing the firmware, but now the file is there why does it tells it can't find the file ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1065400 Title: Support for loading Broadcom bluetooth firmware To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1065400/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
