[Hilo] Why I fail to use HiloV2 as TCP server? I mean the client cannot reach the Hilov2 server, even the TCP server got IP address of “10.195.8.249”.
Answer: If you use HiloV2 module as TCP server, there are some requirements on the SIM card. The subscription must allow a public IP, a routable IP, or a static IP when you setup the PDP context with the APN.
For most operators, the default subscription does not grant you with such an IP, since this kind of IP is very rare.
If the IP is public and routable, it will be accessible from anywhere in the Internet. And it can succeed with a DOS command of “ping”.
