Patent attributes
Techniques for facilitating communication between an implantable medical device and an external device are provided. In one example, a method comprises broadcasting, via communication circuitry of an implantable device, a first set of advertisements at a first advertising rate according to a communication protocol. The method further comprises determining that detection circuitry of the implantable device detected voltage induced by an electromagnetic field at an interface between tissue of a patient and electrodes of the implantable device and in response to the detection of voltage induced by the electromagnetic field, broadcasting, via the communication circuitry, a second set of advertisements at a second advertising rate according to the communication protocol. The second advertising rate is greater than the first advertising rate.
