Bluetooth Serial Terminal for Windows 10

You can use this App to communicate with Serial Bluetooth devices like the RN-42, ESP32, that are used for arduino projects and other custom projects. Make sure to pair the device first in PC Settings.

Use the rfcomm protocol to communicate with serial bluetooth devices.
You can send and recieve data in either hex or string format.
UI more responsive while updating terminal.
Bytes that do not have proper ascii mapping are converted to space characters.
Transmit data is displayed on terminal if it is successfully sent.
Communicate with Serial Bluetooth devices.
