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.
