I'm considering to build a bluetooth keyboard by myself later on with ESP32 as its microcontroller.

I did found a topic on Espressif forum saying "will implement it eventually". Thanks for your interest in ESP32!


Okay got it, thanks. By the way, will it be released before November, ? Yulong-espressif Hmm I just would like to design a bluetooth mechanical keyboard by myself. Yulong-espressif Ahhh nice By the way is there any links available?

I've googled it and I can't find any further details about this hardware demo kit. I can't seem to find any HID keyboard demo in the repository yet but I would be very happy if one was available.

Is it possible to get a link or nudge in the right direction? The other examples have been extremely helpful. Yulong-espressif Where would I find the keyboard demo code? Yulong-espressif just curious if there are any updates.

I would really really like an update for this! I so want to get a pcb with ESP32 inbuilt for a custom mechanical keyboard as well! Yulong-espressif Hi, did you forget to push the keyboard demo? TianHao-Espressif Yulong-espressif so Why is this closed FayeY? Did I miss an update? I am already using BK as an interim solution however it is slow and a bit crashy for my particular operation I am reluctant to spend time fixing it because I am waiting for this version to come through.

My product is intended to be commercially available eventually and therefore the licencing for BK is not ideal. Hi 6enno Could you tell us a bit more about your experience with BTstack. It should neither be slow nor crashy. By default, full logging, incl.

Emulating A Bluetooth Keyboard With The ESP32

HCI data is activated and this will slow down everything, but it's there for development only. BTstack is not thread-safe. If you call it from a different thread, it will not work. If you have all Bluetooth code on the main thread, it should not crash. Please provide some test code for further investigation.

Hi mringwal Reading back my message, it sounded harsh and I should apologize. I didn't mean to suggest that BTStack itself was crashy and I am aware of the synchronization limits however my particular application involves a lot of high frequency interrupts and context switching between several threads. This will require me to time particular activities and make very specific modifications to the BT code.

Because this product is being developed with the view of going commercial, it will be difficult for me to navigate the licencing which is not free for commercial use as is the Apache licence for the overall esp-idf.Users browsing this forum: Google [Bot] and 42 guests.

The device connects fine, but after a short while, however, my Bluetooth driver on the Windows device hangs and all the Bluetooth devices, including keyboard and mouse, stop functioning. Only a reboot will help. I've cobbled together a somewhat working HID Keyboard example using as a basis for my own, to perhaps avoid the problem, but to no avail.

My own HID example is similar to asterics, but provides no mouse output. The idea is to use BLE only not dual modeand allow a user to send 3 different keystrokes to an attached computer. It builds and flashes fine. I'm using the esp-idf from yesterday from GitHub. Since none of my other devices are causing such a problem, it's a sure bet that the ESP32 code is causing the problem. Can anyone give me a hand with this?

I've been banging my head for a month on this, and I'll probably get fired for it. After the code is a dump of my log over the COM8 port. My windows system log doesn't seem to note anything, so the Windows driver chegewara had a nice adjective to describe it seems to be choking, perhaps overflowing some buffer??? To repeat this failure, you may need to invoke the sending of the keystroke about times.

Go to your esp-idf workspace 2. On Windows 10, go to the Bluetooth device in settings and connect the device 7. Second, the replies I am sending are delayed because the moderator needs me to be a part of the forum just a little more time before the replies are immediately posted. Amazing, but it also seems to find it's way to reconnecting if I disconnect the device. I am going to modify the code so that the device can go into deep sleep, be woken up by a button press, and then check if it can reconnect.

Chegewara, I'm guessing that the idle priority was killing the ability to send properly timed responses back to the Windows driver. I'm also guessing that the stack size was more likely the culprit, due to the fact that the original code had '5' instead of idle priority. Should I assume that the reconnect should now occur without troubles, or do I need to add anything extra to the nvs lines?Status: Basic port incl.

Multi threading calling BTstack functions from a different thread is not supported. Each example project folder, e.

Please run the command again after updating the BTstack tree e. Compilation fails with older versions of the make tool, e. It assumes an I2S Codec connected as follows:. BTstack is not thread-safe, but you're using a multi-threading OS. Any function that is called from BTstack, e. For other situations, you need to provide some general 'do BTstack tasks' function and trigger BTstack to execute it on its own thread.

To call a function from the BTstack thread, there are currently two options:. With both options, the called function should check if there are any pending BTstack tasks and execute them. The 'run on main thread' method is only provided by a few ports and requires a queue to store the calls.

This should be used with care, since calling it multiple times could cause the queue to overflow. We're considering different options to make BTstack thread-safe, but for now, please use one of the suggested options. Skip to content. Branch: master. Create new file Find file History.

I have no experience with IDF and the tool chain and how to integrate those stuff with arduino. Maybe this will come in the future. That would be the first step towards an Arduino encapsulation. OOOh thats cool. But scary as well. If I get a sense of that story, it is a replacement for the Bluetooth stack supplied by Espressif which I believe is based on Bluedroid stack implementation. Yes so this might be a problem to have both stacks available at the same time in an Arduino library.

New day, new lessons:. My esp32 just become HID keyboard. ANd now its HID mouse:.

Oh no, just fooled my laptop by setting appearance. The rest of code has nothing to do with hid keyboard. But i may do some research and see if this is hard to do. I have some good news and some bad news.

esp32 keyboard emulator

Good news that work is in progress. Bad news is driver crash under windows with error code 0x0a device cant start. I can say for sure what is the reason, but its a chance that hid keybord requires secure connection and we dont have implemented it yet.

My next step will be to rewrite code in esp-idf and see what happen and maybe add some security there. EDIT more good news, my samsung s4 connects to esp32 hid keyboard, so now i have to find way to send some text.

I have good news. Esp32 hid keyboard is connecting with my android phone and i can send text. This mean hid keyboard works, at least software part. Still is some work to do but we know it can be done. I just need a running starting point for the Arduino IDE Im not sure yet, i will provide code or share links ive been using during research.

Im thinking about writing blog article about this. This is very important documentation if you want to play with HID devices. This is why I was looking for a nice wrapper for the Arduino IDE so that you can fire up a example project, hit flash and project runs Can you wait few days, im still working on arduino code. At the moment im just sending random letter but i still missing one thing.I just need to have a function like [login to view URL] "my text!

I'm working on More. Hi, how are you brother. I have great experience with ESP32 and Arduino, i have done a lot of projects in this field, just award me the project so that i can start working on it.

Last year I realized a similar project with an ESP Thus I have to tell you the keyboard emulation cannot be done without additional hardware typ.

Note: Due to frequent breaking changes within the esp-idf and all build tools, we recommend to use a specific version of the tools:. After a successful setup, you should be able to build the firmware by executing 'make flash monitor'.

Due to this encoding in a bitmask, more than one button might be sent in one command.

Releasing the mouse buttons is done via setting the corresponding bit postition to zero and sending the mouse command again. Setting a keyboard locale is done with the "KL" command.

The typical approach to emulating hardware is to replicate the hardware programming interface the API. If you are unfamiliar with the benefits of TDD or test-driving python, I encourage you to take some time to Google and learn. I prefer the pytest library over the unittest library that comes with python3, but you are free to test as you choose. Take a look at the examples folder in the GitHub repository.
