Hi,

I finished building my keyboard by following your tutorial. I used a custom build GH60 mechanical keyboard for the project. GH60 has several layers and can act as a mouse too, so I don't know whether it's recognized as a combo device?

The relay works fine on Android and iOS (I haven't tested it on a macOS). The problem occurs when using the keyboard with windows. The pairing process does not have any problems and connects as it's supposed to. But when start typing the is a noticeable lag and register several key inputs for a single stroke. Like for "asdfg" it types "asddddddddffffffffffffffffgggggggggggg" with a huge lag.

As you know I have added some modification to the build.
-> Soft latch switch for turning ON/OFF
-> Auto shutdown timmer
-> RGB LED as an indicator

I was unable to find any bugs which could cause that. Any ideas?

It appears you're using the same serial pins as the ones that are used to flash the arduino.

why not use SoftwareSerial, which allows you to simulate serial ports on different pins?

I just stumbled on your project, and it is currently late, but I will submit a pull request soon™ to do that.

I noticed that while pressing NumLock it changes actually switches the status, but keyboard LED is not showing this.
Interestingly with the USBHIDBootKbd.ino Indicators work fine ( without switching it the status on the connected device)
I was trying to compere this code to Code here to USBHIDBootKbd (part of USB 2.0 shiled library, and could not isolate the difference.
Do you have any ideas on how to fix this ?
(Thanks a lot for the code and the effort!)

Hello.
I am not into hardwares and arduino stuff, but I was really interested by the video you made on youtube about HID Relay.
I am currently looking for a way to transmit USB HID reports (signals) directly to the PC, so there is minimal latency created.
I have found that USB HID signals and Bluetooth HID signals are almost identical, so I am wondering if directly feeding the signal to the pc via bluetooth be done.
If it cannot be done using bluetooth, I would like to build a simple dongle instead of bluetooth, so the signal will go like:

PC---Dongle---RF Signal---Transceiver---USB Device.

So, it's basically a wireless USB cable.
Are you interested in this project? I think this might help your channel

I'm new to electronics and I have a bunch of spare pro micros so I was wondering if I could use those instead.

I am looking for a device that has this capability, I only have the output of a USB hub with 2 HID (mouse and key), if this project is not compatible, how to perform this split?

Hi!

I want to convert my X-Arcade USB to be wireless.
Do you believe this is a suitable solution ?
Do you have lag for keyboards ?

Thanks!

Hi,

Thanks a lot for a detailed explanation of how to wire it up, great work!

I have assembled it slightly differently, since I am using this RN-42 from Sparkfun, instead of HC-05.
https://www.sparkfun.com/products/12576

I have this keyboard: https://mechanicalkeyboards.com/shop/index.php?l=product_detail&p=1564

My idea is to fit the whole thing inside the keyboard, so instead of soldering HC-05 on top of the board, it attaches directly to FTDI pins, which makes it USB port height.

At the moment it is still outside, and I am powering it from the power supply, 5V.

Bluetooth keyboard is discoverable on my Mac, and I can type without any noticeable delays. But if I press and hold a key, sometimes it works, sometimes it stops after 5-10 characters, randomly, as I type it misses some characters.

Have you noticed something like that? I heard something about fast data mode for RN-42, but I am not sure what is the root cause here.

I know this isn't an issue with the project, but I don't know where else to ask.
I am a beginner in the whole arduino scene and decided to use this project to do my first steps.
Currently, I have the problem that my mechanical keyboard won't work with this. Cheap 5$ Keyboards work, but not my mechanical.
I suspect it is insufficient power to the keyboard, but I have no way to find out.
Does anyone know, if it is possible to power the keyboard externally from a 5V source?

Hello! Is this a valid wiring diagram?

Hello,

I hope this message finds you well. I am reaching out to you because I am working on an open-source project called BrailleTouch. Our goal is to create affordable Braille displays for blind and deaf-blind individuals.

We are currently stuck and unable to get the HID Braille to receive information from the screen reader and continue programming. As someone with experience in this area, your expertise could be of great help to our project.

I believe that an open-source Braille display could be incredibly useful and have many benefits for those who are blind and deaf-blind. Your knowledge of the HID protocol could be particularly helpful in implementing the protocol in our Braille display.

Please take a moment to review our project on GitHub at https://github.com/brailletouch. If you're interested in helping, please let me know.

Thank you for your time and consideration. I look forward to hearing back from you.

Best regards,

Cergio Monasterio

Did everything right, tested with other keyboards (cheap Logitech \ Metoo Zero from Aliexpress), but cant realy figured out why it doesnt work with my Leopold kb...
Maybe someone tested this project with other high-end keyboards?
