This is a measurement of time between transmissions. It is a random value between 0 and the NN value of open delay slots that will be chosen before a retransmission of a packet that is to be sent over multiple hops. It is used to prevent data collisions from occurring.
So delay slots are timed based? I believe that is incorrect.
That is if I set delay slot of 0x05 I have 5 delay slots but what is the time between delays how do I set that?
