Methods and devices for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. A method performed by the EI includes 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. The method also includes changing the scanning schedule, in response to a duration of the scanning the one or more channels exceeding a 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.

Implantable medical device and method for managing advertising and scanning schedules

Methods and devices for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The methods and devices comprise storing, in memory in at least one of the IMD or the EI an advertising schedule defining a pattern for advertisement notices. The advertisement notices are distributed un-evenly and separated by unequal advertisement intervals. The method transmits, from a transmitter in at least one of the IMD or the EI the advertisement notices. The advertisement notices are distributed as defined by the advertising schedule. The method establishes a communication session between the IMD and the EI.

Systems and methods are provided for establishing a bi-directional communication link with an implantable medical device. The systems and methods include an implantable medical device (IMD) and an external instrument configured to establish a wireless bi-directional communication link there between over a wireless protocol. The wireless bi-directional communication link is established based on a scanning interval. The external instrument includes one or more processors electrically coupled to a radio frequency (RF) circuit and a memory device. The one or more processors are configured to define the scanning interval based on an advertising schedule received from the IMD.
