I'm trying to set 2 XBee Cellular LTE CAT 1 modules with static IP address to talk to each other.
I set following parameters
DL(Destination Address) to each other's IP address.
DE(Destination Port) matches to the other XBee cellular's C0
C0(Listening Source Port) matches to the other XBee cellular's DE
I choose AP(API Enable) as Transparant Mode
IP(IP Protocol) as TCP
When I try to send messages in the console mode, there is no message received.
I check the CI(Protocol/Connection Indication) is 0x24
base on the documentation, 0x24 is No server - timed out on connection. What is that mean? Both of my modules are working properly before I sending any message. The RED LED indicator on dev kit board is blinking every second.
I keep both modules' TM and TS at the default setting, 5 minutes.
Here is the copy from documentation about the CI code.
The following table provides the parameter's meaning when IP = 1 or 4 for TCP connections.
0x00 The socket is open.
0x01 Tried to send but could not.
0x02 Invalid parameters (bad IP/host).
0x03 TCP not supported on this cellular component.
0x10 Not registered to the cell network.
0x11 Cellular component not identified yet.
0x12 DNS query lookup failure.
0x20 Bad handle.
0x21 User closed.
0x22 No network registration.
0x23 No internet connection.
0x24 No server - timed out on connection.
0x25 Unknown server - DNS lookup failed.
0x26 Connection refused.
0x27 Connection lost.
0xFF No known status.
