Smartphone becomes transceiver · Voice communication is possible with Bluetooth
You need two smartphones to use this app.
Turn on the Bluetooth setting, then acquire a new device from the menu.
Next, a list of devices that can be connected is displayed, so pairing is performed by pressing the terminal you want to connect.

When you press the start of the call on the call screen after the pairing is finished, the voice is sent to the other party's terminal.
* Your voice will not be sent until you press the start of the call

If you press end of call, audio will not be sent.

I use the connection to the internet for advertisement.
