一、設(shè)備功能

機(jī)智云gokit開發(fā)板實時上傳DHT11溫濕度數(shù)據(jù)，接受控制并進(jìn)行反饋，保持?jǐn)嗑€重連，可以通過開發(fā)板的usb口，用串口工具調(diào)試工具，直接控制esp8266。

機(jī)智云gokit開發(fā)板連接貝殼物聯(lián)

二、硬件

gokit開發(fā)板2.0v，esp8266網(wǎng)絡(luò)模塊。

三、實現(xiàn)方法

1、gokit擴(kuò)展板上的esp8266刷AT固件，參見：機(jī)智云Gokit2代功能板ESP-12F直接刷AT固件透傳方法

2、下載基于ebox系統(tǒng)的stm32，工程文件，點擊下載；

3、復(fù)制下方代碼，粘貼替換下載工程文件中的mian.cpp文件內(nèi)容；

4、修改文件中的DEVICEID、APIKEY、temp_input_id、hum_input_id，分別為設(shè)備id，設(shè)備密碼，屬于該設(shè)備下的溫度接口和濕度接口id；

5、編譯燒錄；

6、進(jìn)行透傳設(shè)置，直接通過gokit的usb口，使用串口調(diào)試工具，向esp8266發(fā)送命令進(jìn)行透傳設(shè)置，可參見：ESP8266透傳設(shè)置腳本，設(shè)置成功后自動連接貝殼物聯(lián)平臺，請透傳8282端口。
