For keeping track of message arriving on the collector we use the result of the
Sensor_sendMsg function which is supposed to be true for a succesfull transmission (acked by the collector).
However I found out that I get false positives from this function.
To test it I shut down and removed power from the collector and after this it still give me true as a result which obviously cannot be the case.
How can I know for sure that a message is either acked or not acked by the collector?
