问题 I want to ask if there is a possibility and if there is how do I send broadcast from my UDP server to client and after that send back response from client to server.

问题 I'm trying to measure the max size of variable I can broadcast using spark broadcast. I didn't find any explanation regarding this issue. did someone measure it? does spark has configuration for broadcast size? 回答1: Limit for broadcasting has now been increased to 8 GB. you can find the details here. 回答2: It's currently ~2GB.

Maybe I am missing some ndis driver options and wait for a broadcast to complete using this sample MS driver? All I want is the

问题 I have a requirement for an IOS app where a user will start the app, records an audio speech (via device microphone) which would be broadcast to other user on the same network, all this has to be live over wireless connection(WIFI).
