There is provided an exemplary tire pressure monitoring (TPM) system that can use a half-duplex wireless link to communicate between one or more wheel-mounted sensor units and a vehicle-mounted transceiver unit. The half-duplex wireless link enables the sensor units to report sensor readings to the transceiver unit, and it enables the transceiver unit to make configuration changes to the sensor units for improved communication. Some examples of wireless settings that can be modified include modulation settings, data encoding/decoding settings, error correction settings, and transmission power settings.
