Hi,
If I understand you correctly you are trying to bind IP:port several times on the same machine without closing the previous bind ? This is not an option. You can bind UDP and TCP separately with two different pcb's one for TCP and one for UDP. You cannot bind an IP:Port more then one time. This is the meaning of binding. Its like a marriage between IP and a Port. Until you do not divorce you cannot marry again [😊] BR, Noam. ________________________________ From: lwip-users <[email protected]> on behalf of Surya Chaitanya <[email protected]> Sent: Saturday, December 3, 2016 10:44 AM To: [email protected] Subject: [lwip-users] UDP bind error due to address and port reuse Hi, I've been trying to use lwip to transfer UDP packets. In my situation, in the client application, I would like to create 5 UDP PCBs having the same IP address and port number. Inspite of setting the SO_REUSE flag to 1, and setting the SOF_REUSEADDR flag to 1 for all the PCBs, the UDP bind error still persists. Could somebody pls. help me out? Thank You.
