the Bluetooth clock value in the first slot of the packet. The RF hop frequency in the first slot 
after a multi-slot packet shall use the frequency as determined by the current Bluetooth clock 
value. If a packet occupies more than one time slot, the hop frequency applied shall be the hop 
frequency as applied in the time slot where the packet transmission was started. 

In total, 5 types of hopping sequences are defined: 

- A page hopping sequence with 32 unique wake-up frequencies distributed equally over the 
79MHz, with a period length of 32. 

- A page response sequence covering 32 unique response frequencies that all are in an one-to-
one correspondence to the current page hopping sequence. 

- An inquiry sequence with 32 unique wake-up frequencies distributed equally over the 
79MHz, with a period length of 32. (Note: The headset does 

never

 use this sequence) 

- A inquiry response sequence covering 32 unique response frequencies that all are in an one-
to-one correspondence to the current inquiry hopping sequence. 

- A channel hopping sequence which has a very long period length, which does not show 
repetitive patterns over a short time interval, but which distributes the hop frequencies equally 
over the 79MHz during a short time interval.
