What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

Setup: Windows 10 desktop, generic Bluetooth USB dongle with Broadcom BCM20702 Bluetooth adapter
When I first received my keyboard the Bluetooth driver was version 12.0.1.750, released in September of 2015. Broadcom doesn't seem to provide drivers on its own page - Windows just updates them automatically. This is a very common adapter type, so I looked around and found a Lenovo driver for one of the company's laptops that uses the same adapter:

I downloaded the EXE and ran it, which manually installed an older version of the driver, 12.0.0.9050. Once that was installed, I could turn the keyboard off and on, and now it reconnects and types as it should.
I have no idea why this driver downgrade worked for me. I don't know if it will work for you. But if you're feeling frustrated after paying a lot of money and waiting a long time to get a premium keyboard that isn't working correctly, I think it's worth a shot.
