This project can be used as a starting point for developing a nRF51 series mouse or keyboard using Gazell for communicating with a legacy nRF24LU1 USB dongle. It can communicate "out of the box" with the Dongle reference design and the nRFreadySimplePairing.exe application, that can be found in the nRFready Desktop v1.2.3.

This project sends mouse movement packets to the USB dongle when pin 1 is low (button connected to pin 1 pressed) and sends the 'a' keyboard character to the USB dongle when pin 2 goes from high to low (button connected to pin 2 pressed).

The name of the example is gzp_desktop_emulator_pca10028. If you are not using the Keil Pack Installer, you can find the source code and project file of the example in the following folder: <InstallFolder>\Nordic\nrf51\examples\properitary_rf\gzll\gzp_desktop_emulator
