Re: How to deal with full-duplex communication?

When A receives a packet, it sends a return receipt to B. B does the same.
When A and B send a packet at the same time, they receive the receipt of

communication breaks. How to solve this problem.

Thank you for any answer. A sample is welcome more.

Your protocol logic must be prepared to process whatever it receives. It cannot assume that the next message must be a return receipt. If your return receipts contain a serial number of the message being acknowledged then you can maintain a list of pending receipts. (It is possible you will receive several messages before receiving a receipt.)
