Systems, devices and methods for vehicle wireless data transmission, including tire pressure monitoring

A device, comprising:

• input-output (IO) circuits configured to receive tire state data from at least one sensor;
• first wireless circuits configured to wirelessly transmit and receive data units compatible with at least one wireless standard;
• controller circuits configured to, in conjunction with the first wireless circuits,
• in an asynchronous (async) mode, periodically transmit tire pressure monitor system (TPMS) data advertisements (ADVs),
• in a low power state, cease wireless transmissions, and
• in a synchronous mode, in response to a request message from at least one TPMS central device, selectively transmit a TPMS response in a time slot within a repeating advertising interval, then transition to the low power state, and
• transition from the async mode to the synchronous mode in response to receiving a synchronous information ADV from the at least one TPMS central device;
• wherein
• the TPMS data ADVs and TPMS response include tire state data and are compatible with at least one Bluetooth standard.
