Are you running a web server on that module?
Here is a similar thread

How do you get simple data from Local web server created by esp8266?

I've looked high and low and worded my searches every way possible and cannot figure out how to get / read data from a local web server that was created by an Arduino ESP8266. The web server is super simple and only displays two lines of text. I just want to be able to read one of those lines and display it in the app. If you could just point me towards a tutorial on getting the information from my local web server that would be awesome. Everything I keep finding is for HTTP related or msq etc…

If yes, you can try the webviewer or the web component in App Inventor together with the url http://yourIpAddress

// Print where to go in a browser (if applicable)
  Serial.print("You can now access your device at: http://");
  Serial.println(ip);
