Enhanced Bluetooth mechanism for triggering Wi-Fi radios
This disclosure describes methods, apparatus, and systems related to enhanced Bluetooth triggering of device Wi-Fi radios. A device may determine a first Bluetooth data packet including transport data and an indication of a Wi-Fi service discovery, the transport data including a first sub-field and a second sub-field, the first sub-field indicating a length of the second sub-field, and the second sub-field indicating one or more Wi-Fi services supported by the device. A Bluetooth radio of the device may send the first Bluetooth data packet including an indication of a Wi-Fi service. The device may identify a second Bluetooth data packet received by the Bluetooth radio from a second device, the second Bluetooth data packet indicating that the Wi-Fi service is supported by the second device. The device may use a Wi-Fi radio to send one or more Wi-Fi frames associated with the Wi-Fi service to the second device.
