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
