About this app

[Turn your smartphone into a wireless bridge for serial communication!]
This USB Serial Monitor app transforms your Android device into a powerful, portable debugging environment. Perfect for field testing GNSS/GPS modules like u-blox, and DIY electronics or microcontroller development such as Arduino. It features a lightweight MVP (Minimum Viable Product) design, packing only the essential features you need.

[Powerful Features for the Field]

USB OTG Connection: Simply connect via cable to instantly display real-time UART output from microcontrollers and receivers.

Bluetooth SPP Relay: Wirelessly forward serial data received via USB to a PC or another device via Bluetooth in real-time. Powerfully supports wireless data analysis.

3 Formats for Raw Data Logging: Natively supports local saving of standard text (TXT) like NMEA, as well as UBX protocols and raw sensor data in BIN / HEX formats.

By eliminating unnecessary background processes, it reduces battery consumption and runs smoothly even in harsh outdoor environments. Whether you are a professional developer or a DIY electronics enthusiast, use this as your reliable dedicated tool!

*Note: This app is free to use, but contains ads to support ongoing development and maintenance. Thank you for your understanding.
