On Friday I added support for yet another variant of DFU. This variant is called “driverless DFU” and is used only by BlueCore chips from Cambridge Silicon Radio (now owned by Qualcomm). The driverless just means that it’s DFU like, and routed over HID, but it’s otherwise an unremarkable protocol. CSR is a huge ODM that makes most of the Bluetooth audio chips in vendor hardware. The hardware vendor can enable or disable features on the CSR microcontroller depending on licensing options (for instance echo cancellation), and there’s even a little virtual machine to do simple vendor-specific things. All the CSR chips are updatable in-field, and most vendors issue updates to fix sound quality issues or to add support for new protocols or devices.

The BlueCore CSR chips are used everywhere. If you have a “wireless” speaker or headphones that uses Bluetooth there is a high probability that it’s using a CSR chip inside. This makes the addition of CSR support into fwupd a big deal to access a lot of vendors. It’s a lot easier to say “just upload firmware” rather than “you have to write code” so I think it’s useful to have done this work.

The vendor working with me on this feature has been the awesome AIAIAI who make some very nice modular headphones. A few minutes ago we uploaded the H05 v1.5 firmware to the LVFS testing stream and v1.6 will be coming soon with even more bug fixes. To update the AIAIAI H05 firmware you just need to connect the USB cable and press and hold the top and bottom buttons on the headband until the LED goes out. You can then update the firmware using fwupdmgr update or just using GNOME Software. The big caveat is that you have to be running fwupd >= 1.0.3 which isn’t scheduled to be released until after Christmas.

I’ve contacted some more vendors I suspect are using the CSR chips. These include:

  • Jarre Technologies
  • RIVA Audio
  • Avantree
  • Zebra
  • Fugoo
  • Bowers&Wilkins
  • Plantronics
  • BeoPlay
  • JBL

If you know of any other “wireless speaker” companies that have issued at least one firmware update to users, please let me know in a comment here or in an email. I will follow up all suggestions and put the status on the Naughty&Nice vendorlist so please check that before suggesting a company. It would also be really useful to know the contact details (e.g. the web-form URL, or the email address) and also the model name of the device that might be updatable, although I’m happy to google myself if required. Thanks as always to Red Hat for allowing me to work on this stuff.

In early 2017, the Debian Release team pushed Debian 9.0 “stretch” release, which would remain supported for the next 5 years. Named after Toy Story’s rubber toy octopus, this release has just witnessed its third update in the form of Debian 9.3 .
As expected, Debian “stretch” 9.3 ships with tons of security patches and fixes for some serious issues. Prior to this release, on various instances, security advisories for different issues have already been released.
Talking about the bug fixes, there are a total of 68 bug fixes, including startup crash for certain video cards, Debian installer, different package rebuilds for the point release, Python dependencies for different packages, etc.
On the security front, Debian 9.3 got a total of 56 updates, which affect important packages like Tor, WordPress, curl, wget, firefox, chromium, vlc, samba, etc.
Due to being unmaintained and other security issues, libnet-ping-external-perl package was removed.
The Bodhi Linux developers have shipped the freshly baked images in the form of Bodhi Linux 4.4.0. Delivered three months after Bodhi 4.3.1, it’s a normal update release with an aim to keep all the packages up-to-date. So, don’t expect major changes or new features.
Built on top of dependable Ubuntu 16.04 Xenial base, Bodhi 4.4.0 comes with EFL 1.19.1, Terminology 1.1.0, and Ephoto 1.5. It’s powered by Linux kernel 4.13.
