US Patent 11064281 Sending and receiving wireless data

A system and method includes a first device (e.g., a primary wireless earbud) connected to a second device (e.g., a secondary wireless earbud) using a first wireless connection. The first device is also connected to a third device (e.g., a smartphone or smart watch) using a second wireless connection. The second device receives data, such as packets, sent from the third device to the first device by monitoring the second wireless connection. If the second device does not receive a packet, it informs the first device, which sends the packet to the second device.
