1. A method for enabling an implantable medical device (IMD) to establish a communication session with an external instrument (EI) using a wireless communication protocol, the method comprising:
transmitting an advertisement notice in accordance with an advertising schedule during an advertising state, wherein the advertising schedule defines a temporal pattern for transmitting instances of the advertisement notice;
scanning one or more channels for a connection request from the EI following the transmitting of the advertisement notice;
determining whether a valid connection request was received by the IMD from the EI within a specified interval following the transmitting of the advertisement notice;
repeating the transmitting and the scanning during the advertising state, in response to determining that a valid connection request was not received by the IMD, from the EI, within the specified interval following the transmitting of the advertisement notice;
determining a duration of the advertising state exceeds a predetermined threshold without a valid connection request being received by the IMD from the EI; and
changing the advertising schedule and transmitting the advertisement notice 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 transmitting instances of the advertisement notice.
