Techniques for facilitating communication between an implantable device and an external device are provided. In one example, an implantable device includes a data packet component and a communication component. The data packet component can insert information associated with the implantable device in a defined service field of an advertising data packet. The defined service field can be selected from one or more service fields of the advertising data packet based on the information associated with the implantable device. The communication component can transmit the advertising data packet. The external device can include a scanning component that can scan one or more service fields of the advertising data packet via an advertising communication channel, and a communication component that can establish a communication link with the implantable device in response to a determination that a criterion associated with a service field is satisfied.
