MQTT_PublishSensor()

Description

Function publishes sensor data to server. No other options available for this function.
Note that this function is responsible to set a flag for pending sensor registration. Once every second sensors table is being checked for pending sensor capturing. When telemetry frame is being serialized values available at the moment of data capturing are being used.

MQTT_PublishSensor function is not synchronized with data serialization. Async use of this function may result in data being split across two consecutive telemetry frames. In case where data consistency within single payload is required, use publishing synchronization using MQTT_PublishPending callback.

Syntax

MQTT_PublishSensor(sensor_ID);

Parameters

Variable	Input

Variable	Input
`sensor_ID`	Any sensor from Script sensor list.

Returns

Return value	Return explanation
SCRIPT_OPERATION_SUCCESS	Success
SCRIPT_OPERATION_FAILED	Failed
SCRIPT_PARAM_INVALID	Incorrect sensor ID.

Function call example

Example of publishing sensor value to server

main()
{
    MQTT_PublishSensor(Sensor_GPS_coordinates);     // publish Sensor_GPS_coordinates to server
    MQTT_PublishSensor(Sensor_GPS_speed);			// publish Sensor_GPS_speed to server
    MQTT_PublishSensor(Sensor_SignalIN2);			// publish Sensor_SignalIN2 to server
    MQTT_PublishSensor(Sensor_SignalMotion);		// publish Sensor_SignalMotion to server
    MQTT_PublishSensor(Sensor_GSM_PWR);				// publish Sensor_GSM_PWR to server

  for(;;)
  {
      Delay(100);    
  }
