Ok. I can successfully establish a TCP Connection and send data, however, any data returned is not displayed or returned in an API x0B Packet. Anyone else experiencing this? Here is long background story:
I’m Connecting to the XBEE via an FTDI cable connected to an Adafruit XBee Adapter Kit. I’m sending API packets from X-CTU. The same problems occur in Transparent Mode. The XBEE is connected to my wireless access point and I’ve set the router to OPEN security so I could debug the traffic. It DHCP’s the IP Address of 192.168.1.100. In Wireshark I see successful connection to the DEST IP with data coming back.
I’m establishing a connection to a remote web server <4AD03B1F>(188.8.131.52) to port <0050>(80) from port (48879).
Problem #1) I never receive any data back in either Transparent or API Mode. I’m expecting an API packet of B0 (Rx IPV4 Packet). In wireshark I have seen TCP data being returned to the XBEE. [Attached]
Problem #2) If I try the connection again even though the webserver should have already closed the TCP Connection it crashes the XBEE. I’ve even seen the FIN, ACK in wireshark. I receive
 01 04 – Physical error occurred on the interface with the WIFI Transeiver.
[8A] 03 72 – No longer joined to access point.
From that point if I try to transmit I get a:
 01 03 – Transmission was purged because it was attempted before stack was up.
