'''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 definition with an access code (72bit) + packet header (54bit) + payload + [[Cyclic redundancy check|CRC]] (16bit).

'''Asynchronous Connection-Less Link'''<ref>Data Communications and Networking, 4th Edition&nbsp;—– Chapter 14 Wireless LANs, Section 14.2 Bluetooth, Page 439</ref> (ACL) is used when data integrity is more important than avoiding [[Latency (engineering)|latency]]. In this type of link, if a payload encapsulated in the frame is corrupted, it is retransmitted. A secondary returns an ACL frame in the available odd-numbered slot if and only if the previous slot has been addressed to it. ACL can use one, three or more slots and can achieve a maximum data rate of 721 kbit/s.
