Gazell Pairing library
The Gazell protocol is considered experimental for the nRF52 Series.

The Gazell Pairing library enables applications to use the Gazell Link Layer to provide a secure wireless link between Gazell nodes. The library is customized for pairing a Gazell Device (for example, a mouse, keyboard, or remote control) with a Gazell Host (typically a USB dongle).

The Gazell Pairing library has the following features:

- Close proximity pairing
- AES-128 encryption
- Secure key exchange
- Dynamic update of key during runtime
- Storage of pairing parameters in non volatile memory
- One time programmable (OTP) device compatibility
- Backwards compatible with Gazell Pairing library for nRF24L devices.
