Abstract

A system for recovering pairing information of wireless devices is provided. The system may include a first device (such as a mouse) and a second device (such as a dongle) that are wirelessly paired. The system can determine a pairing information damage in one of the first device and the second device, and can automatically recover the pairing information without even noticed by the user. In this way, the system can be less affected by the pairing information damage, and can have extended product life and improved customer experience.
