After creating a UDP server socket using AT+CIPSTART (mode 2), we can receive packets via the +IPD message from different IPs. Is there any undocumented AT command that enables the remote IP address and port to be included together during +IPD ? We know that AT+CIPSTATUS can be used to get back the remote IP address and port but if multiple UDP packets from different IPs are received in a short period of time, it seems that we will have an issue getting back the remote IP using AT+CIPSTATUS since all the packets are being identified using the same link id.

It would be much better if the remote IP and port is send together with the +IPD message.(for UDP and TCP packets).

Regards,
Hew
