Access Code Sensitivity To BER
Original Post: access code sensitivity to BER (SIG Forum)

The access code
precedes every baseband packet , and is used to determine what packet is
destined for what piconet. However it is not protected (by such methods as FEC ,
CRC etc.)
Question
The access code is rather long (68- 72 bits) , how
sensitive is it to high bit error channels. I.e. how many bits in the access
code can be "wrong" for it to still be accepted by a slave as correct?
Answer
This is not implicitly covered in the Bluetooth Spec. It
is up to the designer to specify how many bit errors will be tolerated ,
rather than how many bit errors the access code can tolerate

Protection for the Access Code'
