Is there any way i can use this with BLE-Keyboard Project, without the need reconnect?

Basically i have a rotary encoder and want to use it to send VOLUME UP/DOWN commands & when switching the mode by pressing the button of the rotary encoder, switch into horizontal scroll mode.

If i understand correctly, i would need to disconnect and reconnect as the other device, or would there be a more comfortable way to do so?

So far i used HID-Project library via USB on a Arduino Micro, but want to move to an ESP32 and Bluetooth

Also i saw some issues about disconnecting and reconnecting not working and they have to soft reboot. So i guess my project is not possible that straight forward?

I am trying to make my Bluetooth mouse and keyboard but I can the two at the same is show me error please make combined library that work as keyboard and mouse at the same time.
Thanks For Making These Type Of Library That Can Always Help.

Hello,

I noticed that, within BleMouse.cpp, xTaskCreate() was being called. I have a few questions regarding this.

1. The example code(specifically ScrollAndMouseMove), that is included with this library, doesnt seem to implement an RTOS structure. How are you able to implement a task, while also being able to use a main-loop coding structure?
2. What library are you using to call xTaskCreate()? I am having trouble finding it and I would like to reference it, in order to understand your code better.

ESP32-BLE-Mouse is so easy to use! Thank you x 100! I'd like to extend it to support accelerometer-based gestures. I'm working on my wrist watch project (https://github.com/frankcohen/ReflectionsOS). It has an ESP32-S3, accelerometer, compass, and GPS, no touch screen, no buttons. It's all open-source. I am searching for code to interpret accelerometer data for gestures. Like making a big circle would register as a gesture, or shaking left and right a few inches would register as a gesture. I can't depend on the Internet being available while this is in operation. I could use a Tensor flow or other approach for training while networking is available. What have you seen? Pointers please. Thanks! -Frank

Hello sir!

I am using an esp32 with your code and it works great on any bt device except the PlayStation 4, I can see how the ps4 finds the device but there is no way to pair it...

Could you tell me what could be happening?

Thanks in advance!!

Wi-Fi is faster than Bluetooth, the response time in Bluetooth is 60ms, but Wi-Fi is 20ms, 3 times faster
If wifi is supported then the library can be used more widely with other chips, like esp8266, which is cheaper than esp32, but it doesn't have bluetooth.

Hi, is it possible to use the lib as ble Touchscreen, to send absolute coordinates to a device?
if so how would i do this?

I am trying to forward the input from Logitech USB keyboard and Logitech USB mouse using this library. The keyboard is working aside from the media keys.

The mouse is sending an 8 byte input report and I don't understand entirely which byte is representing what.

Example:
0x2 always the same
0x0 buttons
0x0 always 0x0
0xFF x axes
0xF y axes, but also changes when x is negative
0x0 changes when y is negative
0x0 scrolling wheel x
0x0 maybe scrolling wheel y but with my mouse I cannot scroll horizontally

I've seen only examples with 5 byte input reports. I updated the report descriptor with the input device's descriptor but still not working. I think the issue is still the device descriptor but I don't have the knowledge to debug it. The descriptor is 177 bytes whereas in the example code it's much smaller. I don't know if there is a limitation.

Mouse library works fine on iphone7 after removing line 28 in BleMouse.cpp
However, I can't get any analog readings from my ESP32 (Dev kit or Wemos). As soon as "bleMouse.begin();" command is given then analog reads stop.
Is it just me? Can someone please try the simple sketch below. Without any connections it produces random numbers as expected.
Than remove the '//' in front of 'bleMouse.begin()' and run again. All I get is zeros.

#include <BleMouse.h>
BleMouse bleMouse;
void setup() {
Serial.begin(115200);
Serial.println("Testing Analog read");
// bleMouse.begin();
}
void loop() {
Serial.println(analogRead(33));
}

Thanks

Is there a way to set the PID and vid of the mouse?

Is this open source? No license was specified

Feature request: drag and drop (mouse-down, move and mouse-up). If this feature is possible to achieve with current version, then please add an example. Thanks.

Can it work like as abs mouse on windows which move on pixels provided like:

AbsMouse.init(1920, 1080);

AbsMouse.move(Xcordinate, Ycordinate);

I've uploaded an example, I can pair using two different windows 10 laptops and my android phone. However, I tested on two other windows 7 machines and they cannot see the Bluetooth device at all.

Hi, thank you for publish good tools.
I want to use this BLE mouse on Android.
Now scroll down and up is not smooth.

Is it possible to scroll smoothly?

I set 100, and he moves to the right. I set 200, and he moves to the left. Why?

I got an error when I try to write examples on Arduino.

I fixed this with rewriting ln164 in "BleMouse.cpp"
from
bleKeyboardInstance->onStarted(pServer);
to
bleMouseInstance->onStarted(pServer);

Thanks for your great project!

I connected esp32 to an android phone, how can I move mouse cursor to the center of screen whatever the mouse had been moved to any position.

To make it connect on Windows 10, I had to do the following:

replace the first line below by the next 3
//pSecurity->setAuthenticationMode(ESP_LE_AUTH_BOND);
pSecurity->setAuthenticationMode(ESP_LE_AUTH_REQ_SC_ONLY);
pSecurity->setCapability(ESP_IO_CAP_OUT);
pSecurity->setInitEncryptionKey(ESP_BLE_ENC_KEY_MASK | ESP_BLE_ID_KEY_MASK);

I am not knowledgeable on BLE, I cannot make a properly documented pull request.

I haven't been able to make my ESP32-s3 work with MacBook Pro M1 as well as Intel chip, It shows the device in Bluetooth devices list, pairing, In verbose mode, it logged following
E (15363) BT_GATT: GATT_INSUF_AUTHENTICATION
On intel chip in addition to ablove it showed following

E (57040) BT_BTM: BTM_GetSecurityFlags false

E (57070) BT_BTM: BTM_GetSecurityFlags false

E (57100) BT_BTM: BTM_GetSecurityFlags false

The connection seem to be broken, Laptop stops showing the device, the ESP32-s3 keeps getting TRUE for bleMouse.isConnected()
The thing I am not sure about is if ESP32-S3 is even supported yet.

does not work for c3

I tested on ipad mini 5. The resolution is 2048*1536.
1、When I set initial x to 0 and call move to increment x by 10 every time. I found that x incremented by about 1300 totally when the cursor reaches the edge of screen in landscape view. That's far away from 2048.
2、When changing increment step from 10 to 50. The final movement along x axis is only about 660.
3、When calling simpleMove(0,0) #19 and then moveTo(0, 100, 1.0, 0, 0, 0) the cursor moves along y by y1. When calling simpleMove(0,0) and followed by moveTo(100, 100, 1.0, 0, 0,0) the cursor moves along y by y2. I found that y1 is larger than y2.

I don't understand why the above experiments happen. Is there any explaination?
Thanks in advance.

I think this library might conflict with wifi.
I put the wifi stuff and BLE stuff in two separate functions. When I comment out any one of them the program running ok. But if not, the program will upload, but the esp32 will reset halfway through starting. In my program wifi starts before BLE. The wifi starts ok, then before any of the BLE mouse libraries been used the chip is crashed.
I think it is because BLE and wifi share the same antenna.
any chance you can modify the library, so before "begin()" were called, the library will not use any BLE hardware, please?

Hi

Can anyone confirm that the setBatteryLevel function actually works?

On Windows, it doesn't seem to work

In the code below for example, I set the battery level to 90% when the device is started, and it shows up in Windows fine, but then I try to reduce the battery level by 1% every 30 seconds, but the information is not updated in Windows.

Any idea on how to get it working?

Thanks

#include <BleMouse.h>

int batteryLevel = 90;

BleMouse bleMouse("BLE Mouse", "lemmingDev", batteryLevel);

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");
  bleMouse.begin();
}

void loop() {
  if(bleMouse.isConnected()) {
    Serial.print("Battery Level: ");
    Serial.println(batteryLevel);
    bleMouse.setBatteryLevel(batteryLevel);
    delay(30000);
    batteryLevel--;
  }
}

BLEMouse.cpp has bleKeyboardInstance->onStarted(pServer); at line 164, so won't compile and link without commenting it out.

I added a sendReport so it can be used with a USB to BLE mouse pass through.

USBMouseReport *report;

bleMouse.sendReport(report->buttons, report->x, report-y, report->wheel);

If interested I can push a PR.

i need use ble mouse and ble keypad ,how can i use then both ,i merged the HID Report Descriptor in keypad and create a new [BLECharacteristic *inputMouse; ] but not work

I want to make a push button that simulates the left click of a mouse How can I do it?

Hi,

I would like to use the new feature in IoS 13 to use an external mouse and tried your lib. However, it seems that ESP32-BLE-Mouse does not work for me to an iPhone 7 with IoS 13.1.2. I e, the ESP connects to the phone but then nothing. Same library work fine to a MacBookPro with MacOS 10.14.6. The ESP32-BLE-Keyboard library works fine (but only a few keys tested) with both these devices. Accessibility settings on the phone seem to be correct. ESP used is a Sparkfun ESP32 Thing.
Anything I can test or try?

Göran

Is there any possibility that there will be an absolute mode? That would be more useful and intuitive since otherwise I don't see a way around resetting the mouse position if it has accidentally 'run against a border', if that makes sense!

Also, sorry, I'm new to this field

Hi,

I followed your work already at th ESP-BLE-Snippets.
The basic Arduino code from chegewara is sending the text.
Now I tried your library but can't get it to work.
Here is my test code:

#include <BleMouse.h>

BleMouse bleMouse;

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");
  bleMouse.begin();
  pinMode(12, INPUT_PULLUP);
  attachInterrupt(digitalPinToInterrupt(12), clickNumLock, FALLING);   // Num Lock
}

void loop() {
}

IRAM_ATTR void clickNumLock(){
  if(bleMouse.isConnected()) {
    bleMouse.click(MOUSE_BACK);
    Serial.println("Buttonpressed");
  }
} 

It compiles with no errors, Win10 and Android are able to connect, but under Win10 nothing happens, with Android the mouse pointer appears and moves a little to the right after each keystroke, no matter which command is sent (MOUSE_LEFT, RIGHT or BACK). Am I doing it all wrong?

btw. do you think, you can include 3 more functions in your library. My goal is to make a simple media controll button with a rotary encoder and with following functions: "play/pause", "Volume up", "Volume down" (eventually "next song"). But I am not able to send these keystrokes over BLE with my ESP32, my coding skills are by far not enough ;).

best regards
Daniel

Hi.
I have slightly understood the purposes of task processing of Arduino.
I wonder ESP32-BLE-Mouse works well without xTaskCreate().
Does skipping(bypassing) this xTaskCreate() invites some troubles?
I believe that skipping may invite some delaying.
However ESP32-BLE-Keyboard does not use xTaskCreate(), doesn't it?

Board: ESP32-C3

If I use the code template below I am unable to reconnect to the board with my PC. The board auto-connects fine with the first instance of bleMouse.begin() but does not reconnect after bluetooth is stopped and restarted. If I use deep sleep or reset the board it will reconnect without issues. The mouse commands are still sent and bleMouse.isConnected returns true after bluetooth is restarted, but there is no connection shown on my PC and it does not receive the mouse commands. I also receive the error message shown below after bluetooth is restarted.

Code template:

bleMouse.begin();
while(bleMouse.isConnected) {
  // send mouse commands
}
bleMouse.end();
btStop();
// do something else
btStart();
bleMouse.begin();
while(bleMouse.isConnected) {
  // send mouse commands
}

Error message:
E (80831) BT_HCI: command_timed_out hci layer timeout waiting for response to a command. opcode: 0x2008

How to calculate the position of mobile phone screen

In case it is relevant for anyone else, I was able to work around Mac OS X not pairing by not sending any commands for 5-10 seconds after it connected. This could likely be tuned lower, but is good for my use case.

Example:

unsigned long connectedMillis = 0; // delay actions until after connected for 10 seconds, because apple is dumb
// ...
BleMouse bleMouse;


void setup()
{
  // ...
}

void loop()
{
  // Start, apple is dumb.
  if(bleMouse.isConnected()) {
    if (connectedMillis == 0) {
      connectedMillis = millis();
    }
    
  }
  
  if (millis() < connectedMillis + (10 * 1000)) {
    return;
  }
  // End, apple is dumb.
  
  // ... 
}

Regards,
Dan

as title is , it means use arduino control iphone?

Not sure this is BLE mouse library issue.
Seem like ESP32 core bug.

I am using same ESP32 board with 3 three IOS device with no problem.
After I restore IOS device A, ESP32 cannot connect anymore. However, device B and C still working.

Then, I use "pio run --target erase" the clear the ESP32 and re-upload the program.
Device A start working again.

Seem like ESP32 core library cannot register new key (this key change after IOS restore), if the device address have registered already.

Any though on how to solve this issue?
How can I clear the registered bond data OR limit the max bond device to 1 (auto de-bond every time).

It´s compatible this function Mouse.move(xReading, yReading, 0)?

sorry this is not a issue..

I am curious it,

does it work in ipadOS ?

I read it

Customize Bluetooth device name/manufacturer
Compatible with Android
Compatible with Windows
Compatible with Linux
Compatible with MacOS X (not stable, some people have issues, doesn't work with old devices)
Compatible with iOS (not stable, some people have issues, doesn't work with old devices)

Only Ipad was excluded from the list.

Hi there,
after running this code esp32-ble-mouse-abs-android.ino.txt with Android 8/9, it enables correctly the absolute mode when moveTo(x, y) goes directly to the target position on Android devices. However this works in portrait mode but in landscape mode, we observed that the virtual enabled zone is still in portrait mode and the mouse cannot go beyond the width of the portrait mode.
It seems difficult to determine if it is due to Android in rotation mode to landscape or some other issue with the HID descriptor and send report ? Have you guys experienced such an issue with Android device in absolute mode ?
Devices tested : tablets (Lenovo and Huawey models along with some android phones) in Android 8.0/9.0.
Cheers.

Thanks heaps for making ESP32-BLE-Mouse and ESP32-BLE-Keyboard
It will make it much easier to use that functionality now

Am hoping you may consider creating ESP32-BLE-Gamepad

A ton of possibilities....

when one device connected the ble-mouse successfully，if i restart the device，it can not reconnect again and can not find the ble-mouse by using any other device at the same time， except restart the ble-mouse，3q！

[build] C:/BleMouse/BleMouse.h:3:10: fatal error: sdkconfig.h: No such file or directory
[build]     3 | #include "sdkconfig.h"
[build]       |          ^~~~~~~~~~~~~

where should sdkconfig.h be and whats inside?

Hello author, I use your library to use ios to connect to the Bluetooth esp32 it automatically disconnected, what error did not report, but Android and Windows can be used normally this is what caused the reason.

could anyone tell me the poll rate of this blemouse?
And how can i configure it.
Thanks a lot!

It connected with pc (win10) just fine, but in phone when I click the esp32 device esp32 thinks all ready connected but phone is not still connected and I gives a error in phone invalid pin (pass key) entered how to fix this help?? or else can I put a pass key so only I can use the device too

Thank you
