How to send text througn Bluetooth or Wifi communication…???

For Bluetooth use send Text block

But the mobile do not connect with others mobile…

You need to first display all the available bluetooth devices in a list picker or listview then after picking the address use the selection in the connect block in the address parameter and then if device is connected then set any label to connected so you can find out whether it is connected or not
