Abstract
Bluetooth has become a cornerstone in wireless communication, especially within the peripheral ecosystem. Despite its widespread adoption, Bluetooth faces significant challenges, particularly in environments with high radio frequency interference. One of the primary issues is that Bluetooth needs to establish a connection before scanning for a clear transmission channel map, which adds an operational load and can impact performance.
Clear channels are critical for Bluetooth connections. However, current Bluetooth technology is limited because it can only scan for a clear channel map after establishing a connection. This post-connection scanning, such as Adaptive Frequency Hopping (AFH), will update the channel map during communication. This limitation highlights the importance of developing a method to obtain the map in advance to enhance Bluetooth performance and reliability.
This disclosure is to implement a new mechanism that allows Bluetooth devices to get the channel map before establishing a connection through WLAN scanning. This pre-connection channel map would enable Bluetooth to identify and avoid congested channels before Bluetooth engages with the link, thereby enhancing performance and reliability.
