Hello, we are currently developing a project where we need to send data from our FMB920 device to a server. Initially, I wanted to test by sending the IMEI number of our device. In the Hercules program, I entered the necessary IP and Port information into the TCP Client section to establish a connection with the server, and the connection was successfully made. Then, I sent the IMEI number in hexadecimal format, starting with ‘000F’, just like in your examples, as ‘000F333536333037303432343431303133’. I am expecting an ACK from the server, either ‘00’ or ‘01’, but no response is coming. Even when I send the IMEI number in the same format using my own C# application, I do not receive any response from the server.
As another method, I entered the IP and Port information, which I will test on my own internet, into the configurator. Then, I added the IP and Port information I entered into the configurator to the AppConfig file in Teltonika’s listener application.
I still couldn’t see the IMEI number in the listener. I am not sure what to do at this point. Could you please help me?
