1. A method for listening to a plurality of channels comprising:
configuring a receiver to listen to a first channel of the plurality of channels;
staying on the first channel and decoding one or more packets associated with a preamble responsive to the preamble being detected on the first channel;
determining in symbol identifiers if respective symbols are detected on the first channel;
staying on the first channel for a predetermined amount of time if a first symbol was detected by a first of the symbol indentifiers and the first symbol was transmitted with a first transmission protocol and a preamble associated with the first transmission protocol was not detected; and
switching to listening to an advertising channel if a second symbol is detected by a second of the symbol identifiers and the second symbol was transmitted with a second transmission protocol and a second preamble associated with the second transmission protocol was not detected.
