Multi-message support

Collaboration diagram for Multi-message support:

Detailed Description

Block object that enables sending multiple sensor data in one message, including battery information.

MyMultiMessage usage example

USE_BLOB is a local define, only for emphasizing the changes needed for using the blob feature.

#define USE_BLOB
 
// Initialize general message
#ifdef USE_BLOB
MyMessage msgBlob(0, V_MULTI_MESSAGE);
#else
MyMessage msgTEMPERATURE(CHILD_ID_TEMPERATURE, V_TEMP);
MyMessage msgHUMIDITY(CHILD_ID_HUMIDITY, V_HUM);
#endif

The code below shows a simple humidity/temperature/battery sensor sending everything in one message:

#ifdef USE_BLOB
  MyMultiMessage blob(&msgBlob);
  blob.set(V_TEMP, CHILD_ID_TEMPERATURE , temperature, 1);
  blob.set(V_HUM, CHILD_ID_HUMIDITY, humidity, 1);
  blob.setBattery(batt_level);
  send(msgBlob);
#else
  send(msgTEMPERATURE.set(temperature, 1));
  wait(10); // the wait() is needed at least for rfm69, otherwise it takes a long time.
  send(msgHUMIDITY.set(humidity, 1));
  wait(10);
#endif

Fitting more messages may become more complex, though:

Todo:

Add logic in MyMultiMessage to handle sending itself.

MyMultiMessage blob(&msgBlob);
if (!blob.set(V_TEMP, 0 , temperature, 1)) {
    send(msgBlob);
    wait(10);
    msgBlob.reset();
    blob.set(V_TEMP, 0 , temperature, 1)
}
if (!blob.setBattery(batt_level)) {
    send(msgBlob);
    wait(10);
    msgBlob.reset();
    blob.setBattery(batt_level)
}
