AT+NSUDP command

Hi,

I am just reading the reference manual of WizFi210/220. The command AT+NSUDP is confusing me. What is the purpose of this command ? Is it to listen at the specified port for an incomming UDP telegram or may I use it for sending a broadcast?
If it’s for ‘listen’: is there a command for sending an UDP broadcast / multicast?

Thank you!

Kind regards,

As you know, UDP doesn’t have listen-feature.

WizFi210 (as UDP Server) would send the data to the client which send the data to WizFi210.
This is for the case WizFi210 have no idea about client-ip-address.

And, to send broadcast-packet, you have only to use broadcast(multicast)-ip-address.
(ex:192.168.0.255)
