@handheldsci Hi, I bought your adapter and it doesn't work correctly for my keyboard. The keys get interpreted wrong (e.g. o-key instead of n-key). I have a k-type keyboard but the hardware-id doesn't match the one you have on your website (1C11:B04D)... I've tried everything including Factory Reset and command mode. What can I do to fix this problem? Note: I have the massdrop-x-input-club-k-type keyboard from massdrop: https://drop.com/buy/massdrop-x-input-club-k-type-mechanical-keyboard#overview I have included a picture of the hardware ID below:

I have a question on if this would work for more a niche situation. The massdrop ctrl has a pretty high power draw for all of its LEDs, definitely drawing over the usb 2.0 standard, needing a 3.0 connection. Since this adapter wouldn't be able to pass through that much power, could this adapter work in the second usb port of the crtl? Without a little power brick plugged into it. So essentially the keyboard would be getting the power from my PC, and the bluetooth adapter would be plugged into the open usb port on the keyboard connecting to my laptop. Would that work or does the adapter need be a part of the chain where the keyboard is receiving its power?

Quick question This comes with the chord that plugs into your keyboard too, right

No cable is included with BT-500. If the cable for your keyboard is detachable, it should come with the keyboard. Otherwise how would you use it?

A long shot, but figured best place to ask. Any idea if this will work with a HHKB JIS layout using a hasu usb board? One of the reasons I didn't go with the hasu board with BT is that I often use several of the Japanese function keys that don't work with his BT board because of the chip being used. Hoping this adapter can get around that limitation...

We don't have a hasu controller so can't answer the question directly but can you put back the original HHKB controller which is tested to work the BT-500? If there is something that the hasu can do but not the BT-500 we will be happy to investigate and improve. The hasu usb controller costs $43 and the bluetooth version $85, a lot more than this product with much fewer (and hard-to-use) features.

The main reason for using the hasu is for the qmk compatibility, which allows me to make layers for various shortcuts (which I know your adapter has some programability), but also for compatibility with Win, OSX, and iOS keyboard layouts (specifically the iOS kb layout has to be programmed in as iOS cannot pick up non-Apple JIS keyboard layouts nor is it allowed in settings under external keyboard layout - for some strange reason). Now I figure as your adapter can run several QMK enabled boards, it should not be an issue, but I just figured I would check with you if anyone else had asked you about this before.

Must read: 25-page User Manual for all the cool features: USB bridging, USB/Bluetooth switching with shortcut, command line interface, powerful key mappings, macros, timers, layers, DIY schematic, etc. You can see how much effort we have put into this product.

Tell me again why my phone needs a keyboard; 'cause you know, I'm thinking if I have a keyboard to begin with, I probably have the computer that goes with it. But if I'm carrying my phone around, say in my pocket, there's not a lot of extra room in there for a keyboard too. So 'splain this thing?!

I agreed using a keyboard with a phone on-the-go is not very appealing. There are many better use cases though: tablets without USB port? Not enough USB ports? Reduce cable clutter? Couch potato scenario where the PC is far away? Key mapping? Macros? etc. etc.

I'm confused as to how this works. Sorry if this seems dumb. So I take my keeb, and plug it into this device, and then I plug this device - into what? What is that thing in the picture? Just battery? Then in theory this could also make my wired mouse I use at my computer - wireless?

You must supply power but not necessarily with a battery pack, which is just one of the options if you need mobility. Battery life depends on the power consumption of the attached keyboard. The internal circuit takes 40mA of current. As an example, if the keyboard takes 20mA, the life of a 5000mAh battery bank would be 5000/(40+20) = 83 hours or 3.5 days of continuous use. For fancy back-lit keyboards the battery life would be substantially lower.

I have no idea how this has such a good rating when comments are filled with troubles and issues. Someone is being dishonest here.

Because nobody bothered to read a single page of the 25 page.PDF manual that explains everything in great detail, and has features that are extremely cool that aren't even listed on the drop. 👍

Hello @eeriedescent, Thank you for purchasing our product and giving the review. First of all, if you are not 100% satisfied with the Adapter, you can request full refund including s&h. No questions asked and no time limit. Secondly, the BT-500 we sent out in the last drop does work with Model-01 from keyboard.io, at least with the one we purchased. See this video: https://www.youtube.com/watch?v=7e-p36ixa94. However, the model-01 has gone through multiple firmware releases, and the BT-500 has problems with some versions. We tried to fix this but was put in back burner a while back. The adapter has very limited memory and speed. It is not able to parse full HID report descriptors, which can be very complex, like a full-fledged operating system. So from time to time we have to do some kludge based on a specific keyboard uniquely identified by USB vendor and product IDs. Unfortunately some of the keyboards, especially those based on QMK including the one keyboard.io, change firmware but use the same IDs so the Adapter can't distinguish different versions. Due to the same resource constraint, the Adapter handles boot protocol better than report protocol (but it does attempt to parse the descriptor). Currently we are confident to say it works with 95% of the keyboards/mice in the market. What other keyboards did you test that didn't work? We would like to know every case of comparability. If you give us the models of the non-working keyboards, for EACH of those that we can verify (and not already listed on our web site), if we can get the adapter to work with it (this is in most cases), we will send you a free adapter. How does that sound? Indeed the firmware is not upgradable by end users. It is certainly technical possible but would add substantial support cost to this low-price product. Nevertheless we do provide free firmware upgrade service, including round-trip shipping if you are in the States. Again, we appreciate your feedback. Obviously nobody likes low rating but every feedback pushes us to make the product better. In this particular case we now know the odd-shaped Keyboard.io Model 01 does have some fans. We better make the Adapter to work with it. Consider this a commitment.
