This satellite module reference design is intended for Bluetooth® low energy passive entry passive start (PEPS) and phone as a key / digital key car access systems. The design demonstrates how control area network flexible data rate (CAN-FD) communication capabilities can be implemented with our Bluetooth wireless MCUs for systems that require higher bandwidth in-vehicle networking communications. Further benefits include reduced power consumption in the sleep state: our CAN auto-addressing method for improved manufacturing: connection monitor capabilities for improved Bluetooth localization accuracy and a compact printed-circuit board (PCB) capable of measuring Bluetooth angle of arrival (AoA) and received signal strength index (RSSI).
