Abstract
Disclosed herein, among other things, are systems and methods for eavesdropping on a data stream for hearing assistance devices. One aspect of the present subject matter includes a hearing assistance system for a wearer including a Bluetooth host device having a transmitter configured to send data including one or more encoded audio streams, and a data channel having an advertisement that includes frequency information, frequency hop sequences, information for decoding audio streams, and security keys for decoding audio stream information. The system also includes one or more Bluetooth slave devices identified by the Bluetooth host device. The Bluetooth slave devices are configured to actively participate in a connection with the host device to aid the host transmitter in deciding which frequencies to use for frequency hopping and in determining which frequencies are being interfered with and should not be included in a channel map, according to various embodiments.
