what is bluetooth acl
Bluetooth ACL. The ACL or Asynchronous Connectionless Communications Link is possible the most widely used form of Bluetooth link. The ACL Bluetooth link is used for carrying framed data - i.e. data submitted from an application to logical link control and adaptation protocol channel. The channel may support either unidirectional or bidirectional Bluetooth data transfer.
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 access code(72bit) + packet header(54bit) + payload + CRC(16bit). Asynchronous Connection-Less Link (ACL) is used when data is more important than avoiding latency.
