Relations between bit error rate and average received signal-to-noise ratio ( SNR) in AWGN channel were derived for three modulation modes defined by Bluetooth 2.0+ EDR new specification. The function expressions of packet retransmission probability and average received SNR of ACL packets were put forward.
