Attribute Protocol (ATT) 属性协议

•An attribute is a discrete value that has associated with it the following three properties: 属性是一个离散值,与之关联的以下三个部分
1.A handle (address) 地址The address of the attribute in the table
2.A type 类型 Tells what the data represents
3.A set of permissions 一系列的权限

•ATT defines the over-the-air protocol for reading, writing, and discovering attributes
译文:ATT为读写、搜索属性而定义无线协议。

•Allows for different permissions to be assigned to attributes, including whether they are readable or writeable, and whether additional security is required for access
译文:为属性,允许分配不同权限,包括是否可读、可写,或者是否需要附加的安全接入

Servers have data, Clients want to use this data

总结:ATT定义了无线协议,包含读、写、搜索等属性(Attribute)。也就是说,ATT的作用,以属性表示。属性包含三个部分:Handle、Type、Permissions。
