Abstract: A method includes receiving, by a central device over a wireless communication link, a first advertising packet from a first satellite device; receiving, by the central device over the wireless communication link, a second advertising packet from a second satellite device; determining a first location of the first satellite device responsive to a first wireless localization value of the first advertising packet; and assigning, by the central device, a first network address to the first satellite device responsive to the determined first location.

Abstract: An auto addressing scheme comprised of a central/master module and satellite/slave devices on a communication bus such as CAN that individually wakes the satellite devices alerting them when to listen to the CAN bus to receive their address, eliminating the need for a separate bus for auto addressing. The wake function is handled by low side n-channel MOSFET switches with current limiting resistors to protect the circuit against short to battery conditions and a voltage divider to step down the voltage to levels tolerable for a microcontroller input.
