ath10k-ct firmware released

I am pleased to announce the latest release of the ath10k-ct firmware for QCA WiFi chips.  The 10.1 (wave-1) firmware has improved survey support, changes to how rate-ctrl retries frames, and includes PMF support.  Full release notes here:

The 10.4 wave-2 firmware includes some significant rate-ctrl improvements, PMF support, and various bug fixes and small features.  Full release notes are here:

In addition, I have uploaded a beta 10.4 firmware that is a rebase of all 900+ Candela patches on top of a more recent upstream QCA firmware.  This is easier to bisect for regressions and has some fixes and other improvements from the QCA firmware itself.  See the beta section if you want to try this out:

Pack a Gateworks Full of Radios

Candelatech strives to provide products that are flexible and quiet. The Gateworks Ventana platform provides a great opportunity to provide a high density virtual access point emulation platform. With a bit of shrewd of modification, this GW5400 model can provide 30 or more virtual WiFi access points.

Keeping that many radios cool is what is important. A bit of aluminium plate and heat conductive tape worked wonders for this platform. We’ve seen it run for a month straight without heat related issues. This is effectively a sealed system. It was warm to the touch, but nowhere near hot.

We are excited about this release!

Open Engineer Position


We are considering hiring another engineer for our business here in Ferndale, WA.

Our best candidate would meet these requirements below, but we will also consider CS or similar students/new-grads with fewer skills and experience but willingness and ability to learn. And if nothing else, we would consider hiring someone just to do some soldering and other relatively straight-forward work for hourly wage on an as-needed basis.

We make network test equipment, including Wifi load generators, RF attenuators, and network impairment emulators. The interesting work is done on Linux, but we also cross-compile a subset of features to Windows and support our GUI on Windows.

We currently have 4 employees, and have just rented a nice new office space in Ferndale. Pay depends on experience and such, but typically we offer very competitive salary (or hourly wages).

* Excellent C++ and/or Java programmer. Perl, html and other such languages are a plus.
* Linux skills (admin, install, configure, trouble-shoot issues)
* Ethernet, Wifi, and other networking skills.
* System Test skills.
* Ability to solder and assemble relatively simple electronics boards.
* And above all, a willingness to learn and do new things with good attitude.

If you are interested, please send resume to greearb x40 candelatech x2E com.

And feel free to forward this to anyone you know who might be interested.
