2. Led.h File Modification

  #define Led_red_off       gpio_setbits (gpiob,gpio_pin_9) 
   #define Led_green_off     gpio_setbits (gpiob,gpio_pin_8) 
   #define Led_yellow_off   Gpio_setbits (gpiob,gpio_pin_7) 
   #define Led_blue_off     Gpio_setbits (gpiob,gpio_pin_6)

   #define LED_GREEN_ON     gpio_resetbits (gpiob,gpio_pin_8) 
   #define LED_YELLOW_ON     gpio_resetbits (gpiob,gpio_pin_7) 
   #define LED_BLUE_ON       gpio_resetbits (gpiob,gpio_pin_6)     

3. ESP8266.h File Modification

#define DEVICEID "XXXXXX"
#define APIKEY "Xxxxxxxxxxxxxxxxxx"
#define CWJAP "at+cwjap=\" xxxxxxxx\ ", \" xxxxxxx\ "\ r \ n"

top two macros define Onenet platform-related, last WiFi SSID name and password, these three macros are modified according to their needs

onenet Platform Operation

1. Set GPIO status

The above command realizes the bright blue led.

2. Read GPIO status

Currently showing blue lit, other three LEDs off
