1. A medical device system, comprising:

  • a first device comprising a control processor, a first power supply, a physiological sensor for sensing a signal in a patient, and a first communication circuit; and

    a second device comprising a second power supply and a second communication circuit configured for bidirectional communication with the first communication circuit;

    wherein the control processor is configured to;

    provide power from the first power supply to the first communication circuit according to a first communication wake-up mode set for a first time period that corresponds to a pre-implant time period for the first device and according to a second communication wake-up mode set for a second time period that corresponds to a post-implant time period for the first device in the patient, wherein the first communication wake-up mode specifies at least one first communication wake-up condition and the second communication wake-up mode specifies at least one second communication wake-up condition;

    detect a first event that satisfies the first communication wake-up condition during the first time period and, in response, provide the power from the power supply to the first communication circuit and establish a first communication session between the first device and the second device, wherein the first communication session occurs during the first time period and is enabled according to the first communication wake-up mode, and wherein, during the first communication session, the first device is configured to receive instructions from the second device to establish the second communication wake-up mode for the second time period; and

    detect a second event that satisfies the second communication wake-up condition during the second time period and, in response, provide the power from the power supply to the first communication circuit and establish a second communication session between the first device and the second device, wherein the second communication session occurs during the second time period and is enabled according to the second communication wake-up mode.
