ARCHITECTURE FOR CONSOLIDATING MULTIPLE SOURCES OF LOW-BANDWIDTH DATA OVER A SERIAL BUS

摘要

Systems, methods, and apparatus are described that provide for communicating coexistence messages over a multi-drop serial bus. A method performed at a first device coupled to a serial bus includes receiving first coexistence information directed to a second device, selecting a communication link to carry the first coexistence information to the second device, generating a first datagram that includes the first coexistence information, transmitting the first datagram to the second device over a point-to-point link in a first mode of operation, and transmitting the first datagram to the second device over a multi-drop serial bus in a second mode of operation. The first datagram may be configured according to a protocol associated with the communication link selected to carry the first coexistence information.
