Hi
I need to get info from 4 ESP8266 devices:
Please have a look at this picture.
My ideas so far:
1) Mesh network, which seems like a lot of overhead, since devices do not need to communicate with each other.
2) Wifi direct, because as I read the manual, ESPs should support it and so do Android. But I still don't know how it should work in real life... There is not much info available as well. THIS
3) Android phone act as a client, and making requests to 4 ESP8266 that are in range and that user can choose, and those 4 sensors should return their current sensor value.
4) I can make each of these sensors act as an AP, but that means I have to connect one of them, get info, then disconnect from it, and then connect another sensor, get info etc... Which is why I offered NodeMCU which can establish multiple connections. Although it
5) Your suggestions
Sorry if stupid question, I work as an Android developer so this all seems too vague for me. But I am a beginner in Arduino/ESP field

- 1) User should be free to choose 4 of them that are in range. So no hardcoded names
2) Sensors should only response their values if they are asked to do so
3) There is no Interner available
4) Sensors should give their info as fast as they can. If Android phone sends them request to do so
5) If it is not possible, I can use NodeMCU as a server, which is connected to Android phone
