Abstract: A method of acknowledging data transmissions for a tire pressure monitoring system (TPMS) sensor module includes generating tire pressure information based on measuring an internal air pressure of a tire; selectively operating a transceiver in an advertising mode and a standby mode; transmitting, by the transceiver, a message including the pressure information while in the advertising mode; on a condition that the transceiver receives, in the advertising mode, an acknowledgement in response to the transmitted message, setting the transceiver into the standby mode; while the transceiver is in the advertising mode and on a condition that the transceiver does not receive any acknowledgement in response to the transmitted message within a waiting period, instructing the transceiver to retransmit the message via a command; and retransmitting the message, by the transceiver, in the advertising mode after the waiting period in response to the command.
