Sorry for long message, my project is a network ESP8266-WiFi scales controlled by mobile application.
* All scales should be connected to same WIFI network and so are mobile phones.
* Mobile phone reads weight from one scale at a time by sending commands to scale static IP and display info on screen twice a second
* Mobile phone read/write items info from\to SQL server(jRDC2)

I do not have any problems with SQL part at all. my problem is the ESP8266 part
Which WIFI mode should I use with ESP8266(AP or ST..)? should I keep connection always on with ESP or establish new one with every command, what is the scenario to maintain the two connections at the same time.
