Read and write serial string from/to Arduino/Android through Bluetooth function.

This app now is really can talk! With the voice output feature this app will speak out the string it receives. You can enable/disable the voice output function through the Settings menu.

This handy app functions just like the Arduino IDE's Serial Monitor (writing and reading serial string) but in mobile way.

Users need to connect this app to Bluetooth modules (not over USB-OTG) such as Bluetooth Bee or HC-06 on the hardware side to start the serial monitoring job or just to other Android devices if they have the appropriate Bluetooth serial string communication function.

There are two ways you can test this app right away. Firstly, download this app to two different Android devices, pair them through Android's Bluetooth menu, connect them together via the app's menu and you will see how they work.

Secondly, you can use my Arduino Robot Joystick app or Kayu Gembira app which needs to be installed and run on another Android device, do the Bluetooth connection using the Connect menu and voila, the monitoring job begins.

Or else, if you want to test this app using Arduino hardware, you may upload "Read Analog Voltage" sketch from the Arduino IDE's Examples menu to your Arduino board, connect the Bluetooth module to appropriate pins (VCC, GND, TX, RX) and connect to this app using "Connect" menu.

What you see on Arduino IDE serial monitor will be exactly displayed by this app.

You can try to chat between two Android devices using this Bluetooth Serial Terminal app (needs to be installed on each device) with Emoji function supported.

This FREE version does not contain any ad. You can set the incoming end character sent by the sender, set the auto hide keyboard function and append carriage return when sending string. It however prevents you to customize the GUI appearance.

If you like the function and practicality of this app, please support me by purchasing the Full version at low cost. With the Full version, you can change the GUI appearance such as text size, text color and background color at your choice.

Thank you for your support.
