How to get remote client's IP and port number for UDP broadcasting?

Gor UDP broadcasting, how should we know where is the message received from? To implement recvfrom function, we need to know the client's IP address and port number. Can you suggest which API in the SDK can be used? Thanks.

Re: espconn_igmp_join

I called the function "espconn_igmp_join" only once. But from wireshark, it shows two igmp_join packets, the second one comes around 200ms later.

Please check.

espconn_igmp_join

May I ask is the information of "espconn_igmp_join" saved in flash?

We found that igmp-join is successfully return. Sometimes, the ESP8266 module will send igmp_join commands again.

The SDK used is ESP8266_NONOS_SDK_V2.0.0_16_07_19.

Re: Can UDP socket support multicast using AT commands?

Hi akouz, Thanks for your information. It basically works. A minor feedback of this "AT+CIPSTART=4,"UDP","192.168.1.255",1300,1300,2 - command to module: open connection 4, UDP, broadcast address, port 1300, time-out 2 sec", 2 is not time-out for UDP, but it is for TCP....
