MIT App Inventor Help

I have made an app using MIT App Inventor and esp8266 where the ESP collects data and then sends to the application

Can you get a response using a browser on your device ?

Where did you get that 137 in the third part of the IP address?

Is that consistent with the setup on your Local Area Network?

the adress IP is given by the esp8266

Do you have access to the settings on your local (home?) router?

There is a mask setting that decides between supporting 3 vs 4 levels of IP address ranges on the local network.

For example, on my home router, I can access a router login dialog at address
192.168.1.1
(proceed with caution and some networking knowledge if you venture there)

Can you go into your ESP code and have it use a different IP address for itself, like instead of 192.168.137.27 use 192.168.1.27 ?

yes I can
Setting Static IP.

    IPAddress local_IP(192, 168, 1, 115);
    IPAddress gateway(192, 168, 1, 1);
    IPAddress subnet(255, 255, 255, 0); 
    IPAddress primaryDNS(8, 8, 8, 8); //opcional 
    IPAddress secondaryDNS(8, 8, 4, 4); //opcional

This tells you that the only IP addresses you can use locally are in the form 192.168.1.x where you pick the x for each device or let DHCP pick for you. For printers and other devices that you want to have stable IP addresses, there is another router setting that sets aside some upper range of IP addresses outisde the reach of DHCP dynamic assignments. (I forget the name of the setting.)

Correction - I got the 192.168.1 IP prefix from the other settings. Some networks use 192.168.0 instead, or go further afield if part of a larger network like a school or business.
