puck on windows "paired" but not "connected" (or connected but not HID)

Hi,

I've been having some issues with my puck(s). Often, when I joined them to Bluetooth, they'll automatically go back to "Paired" rather than "Connected". Sometimes, when they connect, they don't appear as HID device either.

Any ideas?

Here's the snippet where I define the NRF services:

var services = {
  0x180a: {
    0x2a50: {
      value:     [
        0x01,           
        0x6d, 0x04,
        0x2b, 0xc5,
        0x00, 0x00
      ],
      readable:  true,
    }
  }
};

var kb = require("ble_hid_keyboard");
NRF.setServices(services, {
  advertise: [ 0x180a ],
  hid : kb.report
});

Thanks
