This document describes low-latency Bluetooth connectivity in a wireless network in which a central node and a peripheral node establish a connection. During a first connection interval, the peripheral node receives a packet from the central node to synchronize communication with the central node, and based on receiving the packet, the peripheral node transmits a first fixed-length packet. If the first fixed-length packet fails to reach the central node, the peripheral node does not receive an acknowledgement, ACK, from the central node during the first connection interval and retransmits the first fixed-length packet during the first connection interval.
