GPRS TCP server

Legacy Open AT
1

Hello,

We are using FXT009 modem and configuring it as a GPRS TCP server.
I was able to configure it as a server for port 80 i.e., HTTP and read the IP address assigned to it.
The commands I used are:

AT+WIPBR=4,6,0              // start GPRS bearer
AT+WIPCREATE=3,1,80,5,8                // TCP server and server socket 1
AT+WIPBR = 3,6,15                           // Read IP address assigned
+WIPBR: 6,15,100.117.228.15          // IP address assigned

But it is not able to ping or connect to the above mentioned IP address(100.117.228.15).
Do I have to configure any other settings?
Can anyone help me?
TIA.

Hello,

Now the modem will behave as a server and it will be assigned with some dynamic IP address. In this case, 100.117.228.15. Since I am using http port, I tried by opening the received IP from internet. But it is not able to open and I did not received any response from the modem as it should respond by

And after few minutes I am getting response as

And I tried to ping the IP address using hercules socket as a client and even through command prompt. But there is no response from the modem.

Now I am in verification phase to implement in my application where the modem will be behaving as a tcp server and should response to the tcp clients which it connects.

Hello ,

Still we are not able to connect from tcp client. Do I have to set any other commands to make it to work as tcp server?
Can anyone help us to go further as we are running out of time?
