nRF SDK 3.0.1, bluetooth peripheral_hid_mouse example fails in connecting windows10 laptop

bluemountain

Development Environment

    - nRF52840DK_nRF52840

    - vscode on Windows10 laptop

    - source code :   C:\ncs\v3.0.1\nrf\samples\bluetooth\peripheral_hids_mouse\

    - vscode + nRF connect

    - no modification on source code and project files

    - compile with default configuration

        - SDK, toolchain  v3.0.1

        - board target   nrf52840dk/nrf52840

        - (no additional settings)

                 Build system default   (which is the default setting)

    - Compile and flash run without error

With Android phone

- Everything is okay

With Windows10 laptop

- Scanning the device runs okay

- But, when I tried to pair, the device print the log as below capture and the pairing failed. 

Does anyone have idea what is wrong in my test ?

Regards,

Kenny

    Hi bluemountain and Turbo J,

    Turbo J said:
    The pairing to the android phone was still in the device memory, you don't want that specifically for any HID device. Those rely on a 1:1 relationship with the host.

    So, I only partially agree with this.

    Firstly, regarding connection, connecting to multiple centrals is technically possible. Multi device control is a real use case that has been done. I personally haven't been convinced of its usefulness to my day-to-day workflow, but I can see how some people might find it useful.

    Secondly, maintaining multiple bonds with multiple centrals is definitely useful. It allows faster switching of which central the HID device connects to.

    Onto the issue, I went ahead and tested the sample myself. I don't have a Windows 10 machine, but my Windows 11 machine paired/bonded with the sample just fine. Here is a log of the device first paired with my phone and then with my laptop. The centrals' identity addresses are redacted.

    Regarding connection, the sample is actually configured to allow connection with two centrals. 
    I am quite surprised to see that possible but couldn't get it to work very well. My Android phones always get disconnected due to 0x2A. This seem to be a problem with my phone though, so I don't draw any conclusion here. It's besides the current topic anyway.

    Try a chip erase / recover to get rid of the android bonding information.

    I second this recommendation. Let's see if a "fresh" device can pair with the Windows machine in the first place. Please also try a different Windows machine, preferably of different make, if possible.

    Great thanks for your comment. 

    I am not trying  to connect to 2 centrals. In my environment, making a 1:1 connection fails with Windows10. But, making 1:1 connection with Android works fine. 

    Since the example connects to windows11 in your testing environment, my issue might be a compliant issue.

    Is there a way to get detail logs to check the detail operations ? 

    Regards,
    Blue
