ESP32-BLE-Keyboard Example - "does not name a type" error
I am trying to get started with the bluetooth keyboard example for ESP32. using the example, it throws the error: "Compilation error: 'BleKeyboard' does not name a type" I have tried to compile this in Arduino 1.8 and 2.2.1 and on multiple computers. all fail to compile. I even tried to downgrade the ESP32 package to 2.x to no avail. What am i missing here?

Keyboard
I like using the ESP32C3. If you don't need a lot of pinouts, the Seeed Studio XIAO ESP32C3 ($9) is awesome for emulating a Bluetooth Keyboard using the https://github.com/T-vK/ESP32-BLE-Keyboard library. Thanks to the Community members who made me aware of the BLE library.

this library is great

Custom keyboard for procreate
It'll be much easier and cheaper if you used a ESP32. Example https://github.com/T-vK/ESP32-BLE-Keyboard

Macro keyboard help, mixed type array problem?
From the library's BleKeyboard.h file, I think the main problem I have is that some keys are just "KEY_" which are type uint8_t.

If you're trying to build a totally custom thing, it looks like there's a library to use the ESP32 as a bluetooth keyboard. https://github.com/T-vK/ESP32-BLE-Keyboard

Used a ESP32 to make an Amazing Bluetooth Rock Band Guitar, I didnt need to solder anything

The BLE Morse code keyboard :) had to rewrite the original code I found, added 3 buttons for Backspace , space and enter. add some visual LED confirmation. next step will be to solder and case it some how. any suggestions for improvements ?
With this library it's pretty simple - have you tried it ? https://github.com/T-vK/ESP32-BLE-Keyboard

How to create USB HID Keyboard device on Esp32-S2?
You will find very little esp-idf based resources, outside of the espressif documentation. If you dive in, you might be able to get it. I’ve been trying to figure out how to get a proS3 board to be used as the controller for a Bluetooth keyboard. Your hill is steep. But it can be done MK32 aaaaaand that’s the end of esp-idf related links, in case anyone gets annoyed by links that are not esp-idf, be forewarned the next links are just that. hackaday asterics t-vK best of luck, I truly hope you figure it out and leave breadcrumbs for the rest of us. Or sell your esp s2 board for the big bucks.

[Help needed] MS Sculpt Ergo conversion
It might be worth looking into an ESP32 board and the MK32 firmware. It won’t be as feature rich as QMK, but I think it will get the job done.

Alternative per-key backlight controllers
Hey guys! I'm building my first keyboard and trying to get experience before spending a lot on a nice one. I'm 3D printing the "pcb" (can it even be called that?) and hand-wiring everything. I'll either end up using the MK32 firmware or KMK on an ESP32. Anyway, I was looking at backlight options and found most controllers that can control individual LEDs in large numbers (like the IS31FL3731) are fairly expensive and can be hard to find. Now they might not have as many features, but what about chips like the MY9221 (this uses two) or MAX7219? They cost the same as a few switches and consume very little power. The MAX7219 seems perfect for a budget build and is well-supported, but before I go learn how to make my own custom driver and spend a lot of time, is there a reason these chips are not used?

Burned the MCU on your keyboard? Just hand-wire an ESP32 to make it wireless!
The main event started when I realize I have all the parts to Frankenstein together a working wireless keyboard, all inspired by this post and this post. The Ducky One uses a 15x8 matrix for all of the 108 keys. The way they wired it would be a nightmare for hand-wiring but I am just piggy riding on the existing PCB with an ESP32 that has enough GPIO pins. The firmware is based on the MK32 project but I have to modify parts of it to properly make use of GPIO34-39. That was intended for split keyboards so it is fair that nobody tried to hook up 23 GPIO and left nothing for an encoder or OLED display.
