Hi,

I'm using the BlueNRG-MS as HID peripheral and having trouble with the re-connection process.

In order to reconnect with the central, I use directed advertising.

The central recognize the slave and I get pairing complete event. The problem is that HID service remains encrypted for some reason and thus I cannot send HID reports (GATT services works). I can see that the device is connected.

What is the correct procedure of initiating a reconnecting between bonded devices ? pseudo code will be welcome.

Thanks,

Yon

    Hi Yon,

    What is the application you are testing for HID on the BlueNRG-MS device? I can recommend for reference the HID profile application included in the

    Hi,

    I don't want to use this example because it is based on a compiled closed library.

    I have mine own code which works fine, just the reconnection causing me problems.

    Regards,

    Yon

    Hi Yon,

    The projects included in the current version of the package (v3.3.0) are based on Profile Library in source form. You can use them as a reference point (e.g., in terms of parameter setting) against your own code.

    Hope that can help.

    Kind Regards

    Andrea
