tcpecho refuses connection ...

[kostyll]

Hello, when I'm running picoapp

./picoapp.elf --tap tap0:192.168.5.4:255.255.255.0 --app tcpecho:192.168.5.4:6669:6669:1400  --app tcpclient:192.168.5.4:6669

or

./picoapp.elf --tap tap0:192.168.5.4:255.255.255.0 --app tcpecho:192.168.5.4:6669  --app tcpclient:192.168.5.4:6669

I get the next error:
No such port 6669
Socket not found...

But if I use udpecho - It works also with netcat
Any ideas ?
