Bluetooth frequency hopping algorithm

Webfrequencies out of the 37 data channels available. Bluetooth provides two algorithms to select the next channel in the hopping sequence from the channel map: Channel Selection Algorithm (CSA) #1 and #2. CSA #1 is a low-complexity algorithm, while CSA #2 adds the ability to change channels within a connection event, and is more secure, as its ... WebFrequency Hopping. 5. Frequency Hopping. The basic piconet physical channel is characterized by a pseudo-random hopping through all 79 RF channels. The frequency hopping in the piconet physical channel is determined by the Bluetooth clock and BD_ADDR of the master. When the piconet is established, the master clock is …
