Plugin

1. Rename the Simple-plugin_temp.js by your applicaton name
2. Chang the plugin path in config/agent_config.json : 'plugin'
3. InitPlugin: InitPlugin  => Refer < InitTest > in Simple-plugin_test.js
4. AutoReport: start auto report interval callback function; Implement to call send data in this=> Refer < AutoUpdateTest > in  Simple-plugin_test.js
5. setSenseData: DeviceOn server or others apps to set sensor value to the service. This callback function will be called and you need to implement a set function with your application at this.
6. sendEventTest: You can refer to "sendEventTest" to trigger a event alarm to local MQTT Broker and transfer to DeviceOn server.

Note

• If plugin need to send OPTS to DeviceOn, OPTS can not be assigned to 0 in plugin's capability. OPTS need to use current timestamp.
