AWS IoT Button触发后仅返回三个参数？技术问询

Hey there fellow AWS IoT developer! 😊

I’ve confirmed that when you press an Amazon IoT Button, it will only send the three core parameters shown in the code snippet below by default:

// Amazon的IoT Button被按下时会发送三个参数...
var body = JSON.stringify({ 
  clickType: event.clickType, // (string) 按键类型；可选值为"SINGLE"、"DOUBLE"或"LONG"
  serialNumber: event.serialNumber, // (string) 设备序列号，位于按钮背面
  batteryVoltage: event.batteryVoltage // (string) 设备电池电压，单位为毫伏，例如"1567"
})

Let me break down each parameter for clarity:

• clickType: A string that indicates how the button was pressed. Valid values are "SINGLE", "DOUBLE", or "LONG" — this is super useful for triggering different actions based on the press type.
• serialNumber: A unique string identifier for your button, which you can find printed on the back of the device. This helps you distinguish between multiple buttons if you have a fleet deployed.
• batteryVoltage: A string representing the button's battery level in millivolts (e.g., "1567"). You can use this to monitor when the battery needs replacement.
