Hi,

I built the app and trying to get it working between two Android devices.
Sadly the pairing doesn't work. When I'm in the BLE HID app (keyboard section) and want to pair it with another device, I confirm the Bluetooth security code on both devices and after few seconds, I'm again ask to confirm a different security code. With a different device, I get the message, that pairing is in progress but never finish.

The device with BLE HID app supports advertising as peripheral. Tested with following functions which are all returning true (according to https://stackoverflow.com/a/28768599):

bluetoothAdapter.isMultipleAdvertisementSupported();
bluetoothAdapter.isOffloadedFilteringSupported();
bluetoothAdapter.isOffloadedScanBatchingSupported();

The tested host devices (brand new Galaxy S8, laptop and another cheap tablet) are also supporting BLE.
Normal pairing between the devices is working. Any clue here?

Regards
Tjado

I am able to connect my android device as input device via bluetooth also my connected device interpret it as keyboard but when i send key from my device it is not getting displayed.

It not work for me

Hello,

I was curious to know where the app still works today, especially on iOS.
I looked into it and I couldn't get the phone to recognize the absolute mouse.

Any thoughts?

How can I send Chinese fonts?
thanks

I am using this app on Samsung Note 9 and connecting it to another android device. Even after both the devices are connected through bluetooth, the keyboard is not working.

After successful pairing, when I start the BLE service ,the pairing auto disconnected. I tried it on multiple devices (Samsung, mi, oppo, motorola).

I am trying to connect phone(o.s- oreo and pie) to windows (windows 10) PC. Please help

Have you tried for iphone as center device,and met that it dit not work?
I did something like you,but i tried ios system version of 13.5 lower , i can use absolute mouse,13.5 higher only relative mouse,
did you solve this problem? using relative mouse is not good.

According to Android doc :

The BluetoothGattServerCallback.onServiceAdded(int, BluetoothGattService) callback will indicate whether this service has been added successfully. Do not add another service before this callback.

The current codes in HidPeripheral.java break this promise and add several services in a row
without proper precautions. This results in race condition and failure adding services. The errors from logcat:

I have created a pull request #10 that tries to solve this by using a local flag. I have tried mutex locks, but they only work when the shared object is accessed from two different threads. In our situation, it seems that the callback is executed on the same thread as the other codes, so they do not work. I am not aware of any better solution, though.

I have tested the fix in my own application on Android 8.0 on a Sony XZ1 Compact device, and it seems to be working fine.

Android docs says 'Not for use by third-party applications.'
BLUETOOTH PRIVILEGED

How do I make it work?

Trying to run this on unrooted Nexus 6, but doesn't seem to work. I see this error in logcat after pairing:

According to docs, BLUETOOTH_PRIVILEGED is not allowed for 3rd party apps.

Hi, I know this project has not been tested on windows. I was trying to test it with Windows 10, I observed that HID Host initiates a disconnection soon after reading the 'HID information'!

I am stuck with this issue and unable to proceed. Let me know if you have any insight here.

Hi,

This is not an proper issue but it could be added feature if you can use single connection to use all input method i was wondering is it possible to do it since we have to send Characteristic.

If it is possible please let me know how to do it or any reference would be helpful.

Thanks,
