描述

在本教程中，您將創(chuàng)建一個帶有按鈕的簡單項目，每次按下它都會向您的手機發(fā)送推送通知。

請注意如何將電池模塊放在底部。它是唯一可以以錯誤方式插入的模塊。

?

2.刷機固件

• 下載HARDWARIO 游樂場，
• 將固件閃存到核心模塊
• 固件名稱：bcf-radio-push-button
• 文檔中顯示了如何刷寫固件。

?

3. 配對核心模塊

您需要將 Core 模塊與您正在使用的 Radio dongle 配對，按照下面的說明查看它是如何完成的。

• 將您的 USB Radio Dongle連接到您的計算機。
• 打開 HARDWARIO 游樂場

?

• 單擊開始配對加密狗上的 LED 應開始閃爍
• 將要配對的設備連接到計算機或插入電池。
• 等待設備出現(xiàn)在表格中
• 它應該使用別名添加設備：push-button:0

?

4. 進口流程

• 切換到功能選項卡

?

如果您沒有看到流程，您可以復制下面的文本并將其粘貼到 Node-RED 的菜單 > 導入 > 剪貼板

5. Blynk 集成

該項目應該與 Blynk 一起使用。HARDWARIO 教程中解釋了如何設置blynk 。

如果您完成了整個教程，您的手機中應該有一個下載的 Blynk 應用程序。

點擊右上角的二維碼圖標，掃描以下二維碼。

?

您將需要一個 Auth Token 來設置 Blynk 和 Node-RED 連接，您可以通過應用程序將其通過電子郵件發(fā)送給您。

• 單擊剛剛導入的項目中的設置

?

• 點擊電子郵件全部

?

• 現(xiàn)在點擊項目中的 Play 啟動它

?

• 您需要將電子郵件中的 Auth Token 放入您在上面教程中所做的 Blynk 服務器設置中。

6. 測試你的設備

現(xiàn)在您只需按下按鈕

推送后，您應該會在手機上收到通知

?

概括
