1. resetar o pool de mensagens enviando type=4, send=true e t_send=1;
2. enviar pinDef do sensor e measure;
3. resetar novamente;
4. reestabelecer a o pool de mensagens anterior do endDevice.

Exemplo:

1. {"nodeDestiny":4208803281,"send": true,"type":4,"pinDef": [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]};
2. {"nodeDestiny":4208803281,"send": true,"type":2,"t_send":1,"pinDef": [0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0],"bmp280PinDef":5,"bmp280Measure":1};
3. {"nodeDestiny":4208803281,"send": true,"type":4,"pinDef": [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]};
4. {"nodeDestiny":4208803281,"send": true,"type":2,"t_send":30,"pinDef": [1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0],"uvPinDef":0,"uvMeasure":4,"bmp280PinDef":5,"bmp280Measure":4}.
