Abstract
An electronic device is described. When this electronic device receives an advertising packet containing an address from another electronic device, the electronic device determines if a connection has already been established with the other electronic device using another address. If so, instead of establishing another connection with the other electronic device using the address, the electronic device continues to use the connection with the other electronic device using the other address. In this way, the electronic device may avoid duplicate connections with the other electronic device, which can occur in communication protocols in which encoded information in advertising frames that specifies an address of the other electronic device is periodically changed.
