Abstract: A method for communicating between a combo-endpoint device, wireless router and a wireless communication device includes monitoring communication patterns of wireless data communications between a wireless router and radio-communication circuitry of a combo-endpoint device, and storing data indicative of communication times of the wireless router based on the monitored communication patterns. The method further includes configuring a frequency-hopping(FH)-based protocol by defining connection periods according to time windows and selected frequencies for wireless communication of data between the wireless communication device and the radio-communication circuitry, and by establishing the time windows to not substantially conflict with the communication times of the wireless router.
