Hello,
I've been trying to get the nRF Desktop Dongle/HID Forwarder to work, ie. I program a nrf52840DK as a HID forwarder, it connects to my bluetooth keyboard, and then the nrf52840 relays the keystrokes from my bluetooth keyboard.
This should somewhat work out of the box, with MINIMAL configuration changes, but I just can't get it to work, it tries to connect, but then just disconnects right after with a `Service not found` log (keep in mind, service discovery seems to work in the Android nRF Connect app, but it uses a database hash?? something?).

I've setup the nrf ble sniffer, which seems to indicate that the ble_discovery fails, for some reason with a `Attribute not found`.
I've made two recordings, one where it works, and one where it does not work.
Hopefully someone can help me out.
Changes I've made in the nrf repo, on revision 6266884de899a254b7f09868d6ad4947d0dfc879.
