Welcome to AAC.

When you say “static IP” are you expecting this to be reachable from the Internet?

Thanks for your response.

No. It is ok, if it is accessible within a range.

This is the tutorial i followed. https://srituhobby.com/nodemcu-esp8266-web-server-relay-control-tutorial-step-by-step-instructions/
It works fine. But, each time a new IP is generated. I want a static ip. So that I can access with the same IP whenever i want to show the demo.

 

Is your demo always running on the same network? Or are you moving around and demoing it at different places using the local network?

You will need to pick an address within your tethering network. Unless they’ve secured it in such a way that it will not allow access unless your MAC received a DHCP assignment ( a common security feature) this code should work.

// Outside setup()

// IP address
IPAddress local_IP(192, 168, 1, 100);
// gateway address
IPAddress gateway(192, 168, 1, 1);
// netmask
IPAddress subnet(255, 255, 0, 0);
IPAddress primaryDNS(8, 8, 8, 8);   // optional
IPAddress secondaryDNS(8, 8, 4, 4); // optional

setup(
bool config(IPAddress local_ip, IPAddress gateway, IPAddress subnet, IPAddress dns1 = INADDR_ANY, IPAddress dns2 = INADDR_ANY);
    ...
)

Since he is tethering to his cell phone, effectively he is. It will be whatever the tethering DHCP server hands out, and it will not change.

Thank you for your reply.
I am planning to use my mobile for all the demos.

Thanks once again.

From where do i get the local_Ip, gateway, subnet, primaryDNS and secondaryDNS numbers? Are they are in my mobile phone or some random addresses?

You should allow the device to get a DHCP address and then record those parameters. Use those.
