功能说明

from IoTcloud import blynk
blynk1 = blynk.Blynk(token='')

• 初始化客户端连接信息

from IoTcloud import blynk
blynk1 = blynk.Blynk(server='', port=0, token='', heartbeat=0)

• 初始化客户端信息, 并配置Blynk服务器地址

blynk1.disconnect()

• 断开客户端连接

blynk1.run()

• 客户端状态更新, 需要放置到主循环中。

def blynk_read_v3(v_pin):
  temp_pin = v_pin
  temp = 100
  blynk1.virtual_write(temp_pin, temp)

blynk1.handle_event('read v3', blynk_read_v3)

• 虚拟引脚读取事件回调函数

def blynk_write_all(v_pin, value):
  print(v_pin)
  print(value)
  pass

blynk1.handle_event('write v*', blynk_write_all)

• 虚拟引脚写入事件回调函数

blynk1.set_property(0, '', '')

• 设置组件属性

blynk1.virtual_sync(pin)

• 同步虚拟引脚状态

blynk1.email('', '', '')

• 发送邮件

blynk1.tweet('')

• 发送twitter通知

blynk1.notify('')

• 发送APP通知
