BlueSPP is a Bluetooth SPP communication tool developed by ShenYao China. This Android application allows users to connect to any device that supports the Serial Port Profile Bluetooth, such as cellphones, MCUs, Arduino, or Raspberry Pi.

With BlueSPP, users can search for Bluetooth devices and choose between Bluetooth client and Bluetooth server mode. The application also provides the option to select an appropriate character set for communication. Additionally, users can customize buttons in the keyboard view.

BlueSPP enables communication with other Android phones and offers the choice between ASCII or HEX display mode. It also allows users to switch between terminal and chat view. The application can connect to a Bluetooth MCU and is compatible with most cellphone Bluetooth modems.

BlueSPP is free to use and is available for Android devices. For Windows Phone users, a separate version of the application can be found on the Windows Phone store.
