Hi, I built windows version of pjturn-client.exe, but cannot verify data sending working as expected. Neither 's' nor 'ss' nor '0' nor '1' command may trigger data receiving callback on peer side. I believe first two commands will send data from TURN relay port to peer STUN port, but I don't see any STUN rx callback. And last two commands will send data from STUN port to TURN relay port, but I don't see any TURN data callback. I traced into PjNath lib, and every call seems return correctly. Did I miss anything, or there is any known issue about the code base? Thanks -Gary -------------- next part -------------- An HTML attachment was scrubbed...
