Claim 10:
11. An implantable medical device (IMD) that is configured to establish a communication session with an external instrument (EI) using a wireless communication protocol, comprising:
a memory that stores an advertising schedule that defines a plurality of advertisement intervals, at least some of which are unequal, wherein the stored advertising schedule is for use in transmitting advertisement notices in accordance with a temporal pattern that distributes at least some of the advertisement notices un-evenly by being separated by unequal ones of the advertisement intervals;
a processor configured to access the advertising schedule stored in the memory;
a transmitter configured to selectively transmit the advertisement notices under control of the processor; and
a receiver configured to scan one or more channels for a connection request from the EI following transmission of one of the advertisement notices by the transmitter;
the processor also configured to
cause transmitting of the advertisement notices by the transmitter in accordance with the advertising schedule during an advertising state, wherein the advertising schedule defines a temporal pattern for transmitting the advertisement notices;
determine whether a valid connection request was received by the IMD from the EI within a specified interval following a said advertisement notice being transmitted;
determine whether a duration of the advertising state exceeds a predetermined threshold without a valid connection request being received by the IMD from the EI; and
change the advertising schedule and cause transmitting of the advertisement notices in accordance with the advertising schedule as changed, in response to the duration of the advertising state exceeding the predetermined threshold without a valid connection request being received by the IMD from the EI, wherein the advertising schedule as changed defines a different temporal pattern for distributing the advertisement notices.
