Abstract: This disclosure describes techniques for renegotiating target wake time (TWT) parameters used for transmitting Bluetooth-encoded audio frames over one or more Wi-Fi channels. In some implementations, a software-enabled access point (softAP) paired with a peripheral device based on a Bluetooth protocol and associated with the peripheral device via a WLAN link transmits one or more first Bluetooth-encoded audio frames indicating a current time-to-play (TTP) value for audio data to the peripheral device over the WLAN link during a first TWT session. The softAP detects a change in the WLAN link, and obtains new TWT parameters and a new TTP value responsive to the detected change. The softAP indicates the new TWT parameters and the new TTP value to the peripheral device in conjunction with tearing down the first TWT session, and establishes a second TWT session with the peripheral device based at least in part on the new TWT parameters.
