Wireless system, method for reconnection, and computer readable medium thereof

摘要

A method for reconnecting a wireless system in an interference environment is provided. The wireless system comprises a host and an end device. The method searches an available communication channel between the host and the end device asynchronously. The end device informs the host of the condition of the qualified channels through the available communication channel. The host determines the most suitable channel from the qualified channels for reconnection between the host and the end device, and then informs the end device of the most suitable channel through the communication channel. The host and the end device hence switch to the most suitable channel.
