Google patents earbud case that sets up Bluetooth while buds boot up
This filing describes a method where an earbud case starts the earbuds' power-up process and simultaneously handles the wireless connection setup with your phone. By doing these two tasks at the same time, the system aims to reduce the waiting time before the earbuds are ready to use.
In the filing’s own words
Wearable audio systems involve initializing hardware components and negotiating wireless connections, which introduces latency during connection establishment. An enclosure device detects a trigger event and transmits a wake-up signal to initiate a boot sequence of an audio device. Concurrently with the boot sequence of the audio device, the enclosure device transmits an identifier associated with the audio device to an electronic device and negotiates a connection state on behalf of the audio device. The enclosure device transfers connection state data to the audio device. The audio device establishes a wireless connection with the electronic device based on the connection state data and a connection request from the electronic device. Executing the connection state negotiation concurrently with the boot sequence facilitates parallel execution and mitigates connection latency.
What exactly they claim (claim 1)
1. A method performed by an enclosure device of an audio device, the enclosure device having a lid and a sensor, the method comprising: detecting, via the sensor, a trigger event, the trigger event comprising an opening of the lid; transmitting, from the enclosure device to the audio device and in response to the trigger event, a wake-up signal configured to initiate a boot sequence of the audio device; negotiating, by the enclosure device with an electronic device, a connection state on behalf of the audio device; and transferring, from the enclosure device to the audio device, connection state data associated with the negotiated connection state, the connection state data enabling the audio device to establish a wireless connection with the electronic device.
