My iOS application needs to connect a device by wifi and exchange data between them. The way of transmission is using the UDP protocol, most of all, it works well. But some part of iOS devices will loss the package always. Even if re-open the application or reboot wifi devices, or reboot iOS devices, it can not be solved. Only reset the network settings on iOS devices could fix it. But this can not make sure that be well always, if occurs in the future. User need to reset network setting again. Are there any brothers know or meet this phenomenon? Thanks for your time to research this.

I have finished the questionnaire that we developed the application will use the framework of the wifi function by this link. Now, I have waitted for three weeks, but there is no email even the rejection email. I don't know how to continue.
