Android Studio - Bluetooth UUID（四十一）

Android Studio - Bluetooth UUID（四十一）：

UUID（Universally Unique Identifier / 通用唯一標識符）是一個全球唯一的 128位 / 128-bit（16字節 / 16 bytes）藍牙編號，它是根據『RFC 4122』規範產生的隨機碼。GATT（Generic Attribute Profile）層中定義的所有屬性都有一個 UUID 值，用於標識通用屬性 GATT 配置文件中的配置文件、服務和數據類型。UUID 用於藍牙以外的許多協議和應用程序中，UUID 的格式、用法在 IETF（Internet Engineering Task Force）公佈的標準 RFC 4122 中定義（技術上等同於 ITU-T Rec. X.667 | ISO / IEC 9834-8：2005 規範）。

藍牙（Bluetooth）GATT-Profile

UUID 有 4 種類型：

1. Time-based UUID (Version 1)
2. DCE Security UUID (Version 2)
3. Name-based UUID (Version 3 and 5)
4. Randomly Generated UUID (Version 4)

大部分是隨機生成的 UUID是會使用 UUID 版本 4。

UUID 版本 4 使用隨機數作為來源，它使用不可預測的值作為種子來生成隨機數以減少碰撞的機會 UUID 可用於以下情況。

• 作為數據庫表的主鍵
• 為 Web 應用程序創建會話 ID
• 表示為事務 ID
• 創建隨機文件名

藍牙（Bluetooth）UUID 的格式

藍牙（Bluetooth）UUID 的格式：0000xxxx-0000-1000-8000-00805F9B34FB，而 xxxx 部份就是所謂的 UUID16 定義。UUID 由十六進制數字和 4 個連字符（“-”）組成。 UUID 的長度為 36 個字符。在開發中我們需要獲取設備的 UUID 欄位，可以通過藍牙測試工具查看 service UUID 和 characteristic UUID，然後每個 Service 又包含了多個 Characteristic，主機和從機之間的通信，均是通過 Characteristic 來實現。
