For example, a device can contain a heart rate monitor and a battery charge detector.* Attribute Protocol (ATT, attribute Agreement): GATT is built on the basis of ATT and is therefore always a gatt/att. The ATT is optimized for the operation of the BLE device. To do this, it uses fewer bytes of data as much

has been widely circulated in Bell Labs and has been revised several times. Since Unics was originally written in an assembly language and the assembly language is specific, and the current computer machine architecture is not the same, every time you install it on a different machine, you have to re-compile the assembly language, it is inconvenient. Later, Thompson partnered with Ritchie to write Unics in higher-level programming languages. At that time, there was a ready-made high-level progr
