ESP32配置MQTT 明确流程 1. 需要在arduino上使用mqtt需要使用库 " PubSubClient "。 2. 使ESP32连接到WiFi网络 3. 连接mqtt代理 4. 订阅主题 5. 发布信息 安装库: 打开arduino选择“工具”里的管理库,在管理库里搜索:Pub SubClient,安装完成后即可使用该库。 在这里先贴上代码,需要可直接copy #include<WiFi...
I covered in aprior postwhy I am going down this path of publishing telemetry to Azure IoT Hub, along with the several ways I have illustrated how one can go about achieving this goal. From direct connection to Azure IoT Hub (via MQTT and SAS tokens) throug...
接下來,我們將ESP-WROOM-32作為Bluetooth裝置試用一下。從“File”-“Examples”-“ESP32 BLE Arduino”打開“BLE_client”程式,並將程式寫入研發板。 程式寫入完成後,將作為BLE的用戶端啟動(BLE是基於伺服器-用戶端的方式來傳輸資料的,相關概念將在後續文章中進行說明)。
可选择平台有:esp-idf、Arduino,CicruitPython,因为前段时间刚用Arduino平台玩过ESP8266模块,所以这里选择Arduino平台进行开发(我才不会告诉你们,我是因为esp-idf编译工具链没配置好)。 简单环境配置 第一步:首选项中开发板管理网址: 第二步:开发板管理器,找ESP32,下载 ...
