1. A method performed by an external instrument (EI) to enable the EI to establish a communication session with an implantable medical device (IMD) using a wireless communication protocol, the method comprising:
scanning one or more channels for an advertisement notice transmitted by the IMD in accordance with a scanning schedule, wherein the scanning schedule defines a temporal pattern of scanning windows that are separated by one or more scanning intervals;
determining whether a valid advertisement notice was received by the EI from the IMD within one of the scanning windows;
determining a duration of the scanning the one or more channels exceeds a predetermined threshold without a valid advertisement notice being received by the EI from the IMD; and
changing the scanning schedule, in response to the duration of the scanning the one or more channels exceeding the predetermined threshold without a valid advertisement notice being received by the EI from the IMD, and scanning the one or more channels for the advertisement notice in accordance with the scanning schedule as changed, wherein the scanning schedule as changed defines a different temporal pattern of scanning windows that are separated by one or more scanning intervals.
