Question about node.ino code

[darkcurrent]

Felix,

I don't understand the following lines that are part of your "node.ino" code:

Code Select Expand

int currPeriod = millis()/TRANSMITPERIOD;
  if (currPeriod != lastPeriod)
  {
    lastPeriod=currPeriod;

Could you explain this to me ?

That's a way to determine when to send a package - ie only once per TRANSMITPERIOD.
