A method and apparatus whereby RF (radio frequency) interference in a Bluetooth wireless communications link is suppressed using an enhancement to the Bluetooth protocol which operates to eliminate noise that is induced on the RF path by external electronic interference. The sampling rate at a Bluetooth transmitter is doubled, and samples are transmitted alternately with and without audio data (e.g., the microphone input data for a Bluetooth headset in transmit mode, or the speaker output data for a Bluetooth mobile phone in transmit mode) included therein. At the Bluetooth receiver, received samples which have been transmitted without audio data are subtracted from (i.e., inverted and digitally added to) corresponding ones of the received samples which have been transmitted with audio data, and the receiver then advantageously uses (only) the (modified) samples resultant therefrom, thereby removing the interference from the signal without reducing the effective sampling rate.
