Grove – BLE HM-11 低功耗串口藍芽模組

描述

Grove – BLE HM-11 低功耗串口藍芽模組

Grove – BLE 使用 HM-11 模組為您的 Arduino / Seeeduino 提供串行BLE功能，如果與 Base Shield 一起使用，它可以非常方便地與 Arduino / Seeeduino一起使用。通過支持 BLE ComAssistant APK，該 Grove – BLE可以在不進行配對的情況下更輕鬆地與您的手機進行通話，當然也可以直接通過AT命令進行設置。您可以在許多條件下使用它，例如機器人控製或遙控設備等。

我們為這個產品準備了一個簡單而方便的命令集，以便您可以使用簡潔明了的代碼來運行該功能。

引腳

Grove連接器有四根導線：GND，VCC，RX，TX。

設計的特點

我們使用TD6810晶片作為穩壓器，所以供電範圍可以是3.3v到5v。此外，還有一個電平轉換電路，確保數據傳輸的準確性。

AT命令

1）查詢模組地址

發送：AT + ADDR？

接收：OK + LADD：地址

2）查詢波特率

發送：AT +波特？

接收：OK +送：[PARA1]

範圍：0〜8; 0-9600,1-19200,2-38400,3-57600,4-115200,5-4800,6-2400,7-1200,8-230400

默認值：0-9600。

設置波特率

發送：AT +波特率[PARA1]

接收：OK +套裝：[PARA1]

例如：發送：AT + BAUD1，接收：OK +設置：1。波特率設置為19200
