Claim 14:
15. A method comprising: cryptographically generating, with a first device, a bit sequence; reading, with the first device, a first portion of the bit sequence, the first portion to include a first candidate address and a second candidate address; reading, with the first device, a second portion of the bit sequence, the second portion including a third candidate address and a fourth candidate address, the second portion different than the first portion; selecting, with the first device, a first access address from one of the first candidate address or the second candidate address based on a first criteria, wherein the first criteria is a function of a first autocorrelation function wherein selecting the first access address includes calculating energy scores of the first and second candidate addresses and selecting a lower of the two energy scores; selecting, with the first device, a second access address one of the third candidate address or the fourth candidate address based on a second criteria, wherein the second criteria is a function of a second autocorrelation function; using, with the first device, the first access address to determine a round trip time (RTT) for Bluetooth communication with a second device separate from the first device; and using, with the first device, the second access address to determine a RTT for Bluetooth communication with a third device separate from the first device.
