Hi,
I've understood masterSlaveDetermination procedure goes as follows:
- EP1 sends mSD message with a value specific to it and also the random
number. 2. EP2 sends back an mSDAck with slave/master info (after comparing its own and EP1's related info). 3. EP1 yet sends mSDAck to EP2 with slave/master info.
Question: Could someone try to explain the reasoning behind the "third message", that is, what is it needed for?
* The MSDSE SDL seems to indicate that the master/slave info in the Ack sent by EP1 contradicting with EP2's info is a possibility. (But EP1's Ack is just the opposite of EP2's Ack according to the same SDL, so now the question is (how) can * happen?)
