Abstract: An internal controller implantable within the body of a patient as part of a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, the internal controller includes processing circuitry configured to establish a radio frequency (RF) communication session with a first external power transmitter that responds to the advertisement. The processing circuitry is also configured to determine when a power transmission status of the first external power transmitter does not match a power receipt status of the internal controller, and then terminate the RF communication session with the first external power transmitter and cause the radio interface to broadcast another advertisement.
