BT Serial Hub & Logger SPP

"Bluetooth Serial Hub & Logger: SPP Multi-Relay is a powerful utility app for developers and engineers that relays and splits serial communication between devices supporting Bluetooth SPP (Serial Port Profile) connections, while simultaneously monitoring and logging data.

Solve issues like wanting to receive single serial data on multiple devices simultaneously or wanting to keep a log while monitoring communication content in real time during IoT development, electronic crafting, and microcomputer communication debugging (Arduino, Raspberry Pi, ESP32, etc.) with this single app.

[Main Features]
■ Multi-device Relay (Hub/Bridge Function)
Connect via SPP with paired Bluetooth devices and instantly transfer/relay received data to multiple other Bluetooth devices.
Functions as a 1-to-N data distribution hub.

■ Real-time Serial Monitor
Monitor transmitted and received serial data in real time on the app screen.
Significantly streamlines debugging tasks like analyzing communication troubles and verifying sensor data operations.

■ Data Logger (Log Saving)
Records exchanged serial data as a log. Useful for reviewing communication content later and conducting detailed data analysis.

[Recommended For]
Developers of electronic crafts/IoT devices using microcomputer boards like Arduino, ESP32, Raspberry Pi.
Engineers performing hardware debugging using Bluetooth serial communication.
Those who want to distribute single sensor data to multiple receivers in a sensor network.
Those wanting to simultaneously monitor communication and acquire logs as a terminal app.

[Features]
Intuitive operation possible through simple UI design.
Supports stable SPP connections and data relaying in the background.

[Notes]
This app uses Bluetooth Classic SPP. It may not support communication with BLE (Bluetooth Low Energy) exclusive devices.
