> @Laczen: @tmedicci @cederom the first problem is caused by udp_input, it also appears when both network interfaces are up before starting the client but the server is not running. The problem is that udp_input tries to send a ICMP response that there is nothing listening on the udp port (ICMP is enabled for wlan0). The device cannot send a ICMP response (it is a ipv6 device). The logic in `udp_input.c` does not take into account this possibility. Hmm, so there is no initial handshake with the server to check if the communication can follow? Or the check is performed on one interface and error information is sent over another interface? Do I get this right? Two interfaces cannot be used at the same time? Is this a limitation of the ESP hardware/implementation or the espstack design limitation? What would be the best / working solution? Using different channels for different interfaces? Maybe @fdcavalcanti could help here? :-) -- This is an automated message from the Apache Git Service.
