The novice consult!!!!!
Assumption that projects have A, B, C three kinds of equipment in the same local area network (LAN), there are 99 C, I want to send this data through the UDP broadcast group 99 devices, every 40 milliseconds hair, in order to avoid using radio affect other A, B equipment, or A broadcast storm...
At the present of what I read, I understand is to write a multicast, then write a client to join this group, but the question now is whether the 99 devices (client) I am unable to programming, that is how I in my program implementation only give 192.168.1.100-192.168.1.198 multicast? Temporary not consider using circular statement,

CodePudding user response:

Or I have a problem understanding of multicast, strives for the answer,

CodePudding user response:

Multicast is to join the group, or how to implement multicast?

CodePudding user response:

refer to the second floor lianshaohua response:

multicast is to join the group, or how to implement multicast?

Which means the necessary programming implementation? Such as want a projector (the target device) to join the group, or the projector is support, or I write program to "put" into the projector running to join the group?
