'''Asynchronous Connection-Less''' (ACL) is a [[communications protocol]]. It is used as a transmission link used for data communication in the [[Bluetooth]] system or as a definitioondefinition with access code(72bit) + packet header(54bit) + payload + CRC(16bit).

<br>'''Asynchronous Connection-Less Link'''<ref>Data Communications and Networking, 4th Edition - Chapter 14 Wireless LANs, Section 14.2 Bluetooth, Page 439</ref> (ACL) is used when data is more important than avoiding latency.

In this type of link, if a payload encapsulated in the frame is corrupted, it is retransmitted. </br>

A secondary returns an ACL frame in the available odd-numbered slot if and only if the previous slot has been addressed to it.</br>

ACL can use one, three or more slots and can achieve a maximum data rate of 721 kbps.
