Can not receive tcp packets in hotspot #211

Hi, Thanks for your awesome library. My problem is that I can't receive TCP packets through the hotspot, but I can get them in a regular network by your sample code. Are there any restrictions in the hotspot network?

When you say "hotspot" is it something from your cellular phone company? Some of them do have filters that prevent you from running "servers". You can run a test using the command-line netcat ("nc") utility to confirm. Something like this to run a server:

nc -l 8080

You can vary the port number. I've found some service providers only block specific common ports (like http, smtp, etc).
