Emulate Bluetooth keyboard and mouse via HID interface to dongle

[TrailLessTravelled]

Looking at the nrf52840 dongle, it seems like it might be very close to being able to emulate a Bluetooth keyboard and mouse via the USB/HID interface. What I'd like to do is send HID codes to the dongle and have it act like a Bluetooth keyboard and mouse on another device via Bluetooth. Is there anything close to this that already exists, or would I need to dive deep into the device and create it from scratch? In this case, I'm looking for a quick solution rather than having the fun of figuring it all out for myself.

Windows PC running my software, sending commands to dongle -> PC/Mac/iPhone/Android controlled as if Bluetooth keyboard/mouse is attached.

Thank you!
