  • System and method for improved power utilization in hart field instrument transmitters to support bluetooth low energy
    Patent number: 11500348
    Abstract: A method includes determining, by a field instrument in an industrial process and control system, a Highway Addressable Remote Transducer (HART) mode of the field instrument. The method also includes, upon a determination, by the field instrument, that the HART mode is a HART On Demand mode, listening for a HART data signal from a HART master device; when the HART data signal is detected, communicating with the HART master device according to a HART protocol; and when the HART data signal is not detected, diverting a current supply allocated for HART communication to a BLUETOOTH Low Energy (BLE) transceiver for use in BLE communication, and communicating according to a BLE protocol.
