BLUETOOTH INTRODUCTION SEQUENCE THAT REPLACES FREQUENCIES UNUSABLE DUE TO OTHER WIRELESS TECHNOLOGY CO-RESIDENT ON A BLUETOOTH-CAPABLE DEVICE
First Claim
1. A method for a Bluetooth-capable device to replace frequencies that are unusable in a Bluetooth introduction sequence due to operation of another wireless technology in the device, comprising:
- determining a frequency pair in a current frequency train, wherein the frequency pair consists of a listen frequency and a respond frequency;
determining whether the frequency pair is unusable for the introduction sequence; and
in response to a determination that the frequency pair is unusable for the introduction sequence, selecting from the current frequency train another said frequency pair from among a set of said frequency pairs that are usable for the introduction sequence.

Abstract
Interference from other wireless technology co-resident on a Bluetooth-capable device may render one or more Bluetooth frequencies unusable for a Bluetooth introduction sequence. In this case, one or more usable frequencies may be substituted for the one or more unusable frequencies to permit the introduction sequence to proceed. The one or more usable frequencies may be selected from a known set of usable frequencies in the current Bluetooth frequency train. Alternatively, a frequency re-mapping process may be used to select the one or more usable frequencies from the current Bluetooth frequency train.
