CC3220: Socket connect failure

Part Number: CC3220

Hello,

I'm running Network Terminal example and seeing failure in establishing a TCP connection.

My setup:

TCP server: nc -k -l 3443 on a MAC, IP address 192.168.0.100

TCP client: CC3220SF, IP address 192.168.0.101

#4 The client initiates socket connect with SYN segment, Seq = 0

#5 The server acknowledges the client SYN and sends its own Seq=0, Ack=1

#6 (this is when it goes wrong), it appears the client didn’t see the ack in #5, so it resends the SYN segment.

The commands I used:

wlanconnect -s <ssid> -t WPA/WPA2 -p <password>

recv -c 192.168.0.100 -p 3443 -nb

Can someone tell me what could have caused this 3-way handshake failure?

Thanks,

Lin
