Disclosed are techniques to use existing BLE broadcast-based signaling protocols to achieve sub-1 ms peripheral-to-central latency even when multiple peripheral devices share the air-time. The techniques adapt existing BLE advertising or broadcast signaling protocols to efficiently allocate air-time to support frequent peripheral-to-central transmissions that are relatively short in duration and less frequent central-to-peripheral transmissions. A broadcast isochronous group (BIG) protocol may be used to reduce peripheral-to-central latency by aggregating broadcast isochronous streams (BIS) from peripheral devices into a BIG. A one-to-many broadcast event that may carry other broadcast data from the central device to the peripheral devices may be used for time synchronization by the peripheral devices and to configure time parameters of broadcast from the peripheral devices. A reverse many-to-one broadcast from the peripheral devices to the central device may be based on the time parameters. The techniques yield low peripheral-to-central latency and natively support encryption in a BLE controller.
