Claim 7:
8. A method of communicating with a tire pressure monitoring system (TPMS) sensor module, the method comprising:
transmitting, by a communication interface device and via an advertising channel, a first wake-up signal as a first directional radio frequency (RF) beam,
the advertising channel comprising a limited bandwidth relative to a data communication link, and
the first wake-up signal being transmitted for establishing the data communication link with the TPMS sensor module;

receiving, by the TPMS sensor module, the first wake-up signal;
measuring, by the TPMS sensor module, a signal strength of the first wake-up signal;
comparing, by the TPMS sensor module, the measured signal strength to a predetermined threshold;
on a condition that the measured signal strength is equal to or greater than the predetermined threshold, triggering, by the TPMS sensor module, a first response signal in response to the first wake-up signal; and
transmitting, by the TPMS sensor module and via the data communication link, the first response signal,
wherein the first response signal includes a sensor identifier (ID) of the TPMS sensor module.
