Russell Bull said:
So, do you really need full duplex?

Jecksons Ben said:
--->Yes, I tried in fullduplex with at least nearly 32 clients(slave).

That might indicate that you have previously used full-duplex, but gives no reason why you actually need full-duplex!

As Russel explained, Master-Slave systems are often inherently half-duplex - hence the question, do you really need full duplex?
