Asynchronous Connection Less
メモ
- It is common for the suffix to be removed from the logical link without introducing ambiguity, thus a reference to the default ACL logical transport can be resolved to mean the ACL-C logical link in cases where the LMP protocol is being discussed, or the ACL-U logical links when the L2CAP layer is being discussed.
デフォルトACLリンク
- LMPの話題のときはACL-Cの意味
- The default ACL is created between the Central and the Peripheral when a device joins a piconet (connects to the basic piconet physical channel).
- This default ACL is assigned a logical transport address (LT_ADDR) by the piconet Central.
- The LT_ADDR for the default ACL is reused for synchronous connectionoriented logical transports between the same Central and Peripheral.
メモ
- The asynchronous connection-oriented (ACL) logical transport is used to carry LMP and L2CAP control signaling and best effort asynchronous user data.
