USB to Bluetooth adapter doesnt seem to work

[unphased]

I'm quite a ways from making progress on debugging this but basically I have one of these:

http://www.amazon.com/Nulaxy-Wired-Keyboard-Bluetooth-Adapter/dp/B00T5YXNL0

And it's not able to complete the pairing procedure...

I guess this is not an easy problem to solve and it is easier to try out more of these devices until we find one that works. I was hoping if it worked out of the box that I could just take the casing apart and embed it into the infinity keyboard and I'd have myself a bluetooth-capable infinity bent plate board.

So I'm wondering if anyone's tried gadgets like this and experienced success.

Does it work with other keyboards? Maybe the NKRO stuff is messing with it's logic

On the bright side, I've measured infinitykb's power usage, it was at 0ma with the device I was using, so if you manage to make it work, the result will be satisfactory in terms of power usage :)

You might be more successful if you set the keyboard in 6KRO mode. There isn't an easy way (yet) from the configurator, but you can do:

U"A":kbdProtocolBoot();

This will set the boot protocol when you press a.

Awesome i will have to give that a try!

Currently I'm just running some configurator-generated layouts, and having some problems where my layer 1 function seems to get locked on permanently... thats totally separate and not necessarily an issue yet

I was able to add this line and it caused the 'a' key to no longer register an a.

However it is not clear how I can independently verify that the protocol changed. For example I plug it in, wait for it to initialize, mash A a bunch of times, no A's are sent by the keyboard, but I can still from this point press my hand down on a lot of keys at once (15+) and they all actually still register. On non-NKRO keyboards what usually happens is it "locks up" till the keys are released. That's not happening, they're streaming away in the same way that they do when NKRO is active.

I tried holding down A and doing the same (putting my hand down on the rest of the board). no change.

And i tried the bluetooth pairing a bunch of times, still no dice. Indeed the serial debug output shows NKRO protocol.

Update

Since I am a good keyboard freak I do happen to have a Ducky board that has its own builtin hardware switch Fn+F12 that toggles NKRO. I verified that if I leave NKRO off, I can successfully register a bluetooth keyboard with my Mac (and iOS devices!!!!!11) using the Nulaxy.

Then, while it is connected, I can toggle on NKRO on this ducky board and it stops working! And upon switching NKRO back off, it works again. So this is a very cool result that definitely verifies the hypothesis that NKRO is the thing that this Nulaxy can't handle.

I am also able to easily test NKRO active by smashing my hand across the keyboard, and it's clear that I just need to find a working way to set NKRO off for the Infinity board. I don't mind it being off 100% of the time so you can just show me how to make it boot up with NKRO off.

Here is the progress I made.

 }

This is fine considering how little I know of what's going on, I am finally able to see boot protocol output in debug over serial.

However, very sad to say, this made no difference and the bluetooth keyboard pairing does not work.

Interesting. I just ordered one of the devices.

Also, I think I may have contact info for the developer of the device.

Thats fantastic, yeah I would imagine having a way to debug the bluetooth device is probably what we need
