Equipped with a deeply optimized TCP/IP stack, built in hardware and software watchdog and a variety of keepalive mechanisms,USR-N520 keeps online all the time. It adopts Cortex-M7 solution,which has a main frequency up to 400MHz, powerful performance, fast transmission speed, and high reliability.
USR-N520 is 2-port serial to Ethernet converter.
Edge computing function, supports configuration of 32 nodes.
Just search in google 'how to forward a port on my router'. So before applying public IP you need to do port forwarding on your router, there are lot of ways to do that. And when in docklight you will execute AT+CIPSTART command then your server will start.
Now you need to first start server on your PC using socket test. Anyhow in my project video for this tutorial, I've explained about the working of these commands. Please follow the datasheet to understand the use of these commands. ( One thing you need to remember that every AT command will be terminated with a Carriage Return character)Īfter that here are the list of commands you need to execute for making TCP/IP connection. So first command is to test weather your GSM module is connected to your PC or not: And after connecting your GSM module to PC using USB to TTL converter you need to give these AT commands. AT commands are the basic initilization for any gsm module.
