Just for people thinking of buying this. I have the previous version MassDrop had a drop for and I never got it working with any keyboard I tried. I tried Ducky, HHKB, Corsair, QMK and TMK customs, etc. To add insult to injury the firmware for these devices are not upgrade-able , total waste of money however YMMV.

joshwtFWIW, I had issues with the 100 version, and it wouldn't work on any devices which registered as anything other than a keyboard. I could get EasyAVR to work on it, but only if I disabled all mouse functions. It worked flawlessly on my Leopold FC600C and a regular PS2 Dell AT101W, just not anything with N-key rollover usb "tricks" or additional USB devices built into it.
The product description for the 500 version specifically says it works with multi-device items. Excited to play around with this one.

Would it work if the power source was within the keyboard itself, or does the design make receiving power through the USB Male mandatory?
Does it by chance have pads for soldering directly if the enclosure is removed? Not a huge fan of the dongle, but a USB based, permanent BT conversion sounds like a fun project.

handheldsciToo bad nobody has taken you up on this! But perhaps you would consider designing a BT module with a 2-pin battery connection that is made to be hard wired inside of a case?

I'm a little confused. You plug your keyboard into the dongle. Then that dongle goes into...another dongle? what is that MPOW device? A battery? And then you can pair your wired keyboard with bluetooth 4.0?

Yeah, I guess in most cases the keyboard shortcuts/remaps that a user wants would be the same over USB and BT. However, there may be some situations where a certain key combination is useful on a desktop system (connected through USB) but would not be functional on a phone or tablet (connected through Bluetooth.) I can't really think of why that would be a limitation for me, but I'm not really one of the keyboard enthusiasts that may find more complex uses for this adapter.

VanceCan't you just add another layer for what you would have mapped to bluetooth or wired directly? Or does this device not do layers?

I think if this product had a battery built in it would be much improved, instead of having to carry a battery pack you could just plug right to your keyboard

Also is the bluetooth adapter that you’re selling on your website the same as this one on Massdrop? I would like to just by one now and not have to wait two months for it to arrive.

kingwongYes the adapter is exactly the same. The packaging could be different especially to international buyers so as to reduce shipping cost.

Compatibility is the key. We have around 100 keyboards (some from Massdrop) and more than 100 mice (not all in the picture) in our lab to test this product! It works with an Arcade Tankstick game controller as well (which is really not a USB game device but a keyboard/trackball on two USB ports).

KikanYes! The ones in the box (not on the shelves) are "bad apples" that are still not working. Sadly keyboard.io is one of them. We did list those on the compatibility page. Another one that isn't working is the Wooting. Those two are our top priority to make those work.

A customer sent two pictures to show how he attached the power bank with BT-500 to the side of his keyboard using Velcro. This power bank is very common (one 18650 cell).

OtrinhIt does two things: (1) Converts a USB keyboard or mouse into a Bluetooth one; (2) Acts as a USB to USB bridge between your keyboard and computer. In either case you can do key mappings (re-map a key to another key), macros (one key press generates a sequence of keystrokes), timers (periodically sends out keystrokes to keep device or connection alive). More features are being worked on such as layers (multiple sets of mappings and fast switching between them), repeats (one key press triggers repeated output of the key until the key is pressed again. Great for gaming), and edge events (treat key down and key up events differently). We welcome feature requests from the community.

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. 👍

Just got my two and tested them with two of my Plancks. Seems like everything in a layer that includes shift or option being held work intermittently (get a key every third keypress or so). Every 25th alpha or so are missed. Space is quite often ignored. Anybody know if there is something that can be done in QMK to remedy this? Otherwise I will ask for a refund. Very disappointed.

I’m using a Planck Rev 6 and my Massdrop x OLKB Preonic Rev 3 without issue via a BT-500. I did have to disable NKRO to get it working as with NKRO enabled, the default for both devices, I get reproducible garbage on the host.
@handheldsci, the documentation mentions 6-key rollover within the context of USB bridging which I found misleading. You might want to revisit the documentation and make it less implied the limitation is only while bridging and instead whichever interface is used a 6-key rollover is enforced regardless of keyboard support for n-key.
Also @handheldsci... please consider adding discreet shortcuts for BT and USB states. C-A-Pause three times (even as a macro) to step through the interface options is not ideal when you could offer two additional shortcuts allowing an interface to be selected explicitly/directly.

You can try my firmware below if you wish to test quickly with NKRO disabled which is what I needed to do for the adapter/Planck/Preonic to work:

(it’s also just one line in your rules.mk: NKRO_ENABLE = no)
