Bluetooth SPP Manager: A Powerful Bluetooth Communication App

Bluetooth SPP Manager is a powerful communication app that enables Bluetooth enabled devices to communicate with each other using the RFCOMM Protocol, also known as the Serial Port Protocol (SPP). With this app, users can transmit data between devices and view various properties of connected Bluetooth devices as well as devices around them. The app also comes with a built-in server that can accept incoming connections from any other device.

One of the most significant features of this app is its integrated Real Time Clock Manager, which allows users to send the current or some predefined time to a remote device. This feature enables users to set the RTC of a microcontroller and further display the current time on an LCD. Other notable features of Bluetooth SPP Manager include speech input for messages, a file explorer for creating, editing, sharing, or deleting files in your workspace, a filter for messages, timestamps for incoming/outgoing messages, several newline characters, and a tablet-optimized layout.

The full version of the app offers unlimited use of the RTC Manager, unlimited file transmission, file filtering, no advertisements, and support for the developer. The app is compatible with Android 9.0 and above and supports communication between Bluetooth devices via SPP (iOS needs Jailbreak). Overall, Bluetooth SPP Manager is an excellent app for anyone looking to communicate efficiently between Bluetooth enabled devices.
