Dante latency is the same as for all other AVIOs, and the Dante AVIO Bluetooth Adapter's device latency should be based on the network conditions, as per any other Dante device.
Bluetooth latency is dependent on various factors including the OS of the device being connected, the audio codec used to stream the audio, interference and losses in the transmission path and the design of the antenna and chips that compose the host device's Bluetooth hardware. As a result, Bluetooth latency is not deterministic.
