Claim 13:
14. A tire pressure monitoring system (TPMS) sensor module having a sensor identifier (ID), the TPMS sensor module comprising:
a pressure sensor configured to:
measure an internal air pressure of a first tire, and
generate first tire pressure information;

a radio frequency (RF) transceiver configured to:
receive, via an advertising channel, a wake-up signal for establishing data communication, wherein the advertising channel comprises a limited bandwidth relative to a data communication link for the data communication; and

a processing circuit configured to:
transition from a low power state to an active state based on the wake-up signal,
measure a signal strength of the wake-up signal,
compare the measured signal strength to a predetermined threshold, and
trigger a response signal on a condition that the measured signal strength is equal to or greater than the predetermined threshold,

wherein the RF transceiver is further configured to:
transmit, via the data communication link, the response signal, wherein the response signal comprises at least the sensor ID.
