連接設(shè)備的第一步是將 SPP LE 服務(wù)和特性添加到 LightBlue 中。要手動執(zhí)行此操作，請在 LightBlue 中創(chuàng)建一個空白的虛擬外設(shè)，然后添加必要的服務(wù)和特性。另一個選項是在 SPPLEDemo 充當服務(wù)器的同時克隆 SPPLEDemo。要克隆 SPPLEDemo，首先如上所述連接 2 個設(shè)備。連接 2 個設(shè)備后，選擇顯示屏右上角的“Clone”選項。應(yīng)用返回到設(shè)備列表，您將觀察到 SPPLEDemo 列為虛擬外設(shè)，如下所示：

克隆后，SPP LE 服務(wù)現(xiàn)在可以與設(shè)備連接。接下來，重新啟動 SPPLEDemo，并在出現(xiàn)提示時啟動該應(yīng)用作為客戶端。下一步，使用 StartScanning 命令進行掃描以查找 iOS 設(shè)備。找到 iOS 設(shè)備后，使用 StopScanning 命令停止掃描?，F(xiàn)在使用 ConnectLE 5c75524c733a 1 命令連接到 iOS 設(shè)備。之后，在 10 秒時間范圍內(nèi)運行 DiscoverSPPLE 5c75524c733a 命令。SPP LE 服務(wù)發(fā)現(xiàn)完成后，在 25 秒時間范圍內(nèi)運行 ConfigureSPPLE 5c75524c733a。如果命令未在這些時間范圍內(nèi)運行，iOS 設(shè)備將斷開與 SPPLEDemo 的連接。配置 SPP LE 特性后，2 個應(yīng)用保持連接，但請注意，如果 iOS 設(shè)備進入睡眠狀態(tài)，則會關(guān)閉連接。運行剛剛介紹的命令后，在 SPPLEDemo 的終端中將觀察到類似以下內(nèi)容的輸出：
