NMEA multiplexer
for Android

Connect any combination of GPS, AIS, depth, and wind instruments via Bluetooth, USB, TCP, or UDP — then route the data wherever it needs to go.

What it does

Multi-Source Input

Internal GPS, Bluetooth Classic, BLE, USB serial, TCP client, or UDP listener. Mix and match any combination simultaneously.

Smart Routing

All incoming NMEA sentences are merged and broadcast to every enabled output in real time. Per-output sentence filters control exactly what goes where.

TCP & UDP Output

Serve data over your local network. Chart plotters, navigation apps, and PCs connect via TCP or receive UDP broadcasts and multicast.

Bluetooth SPP Server

Classic Bluetooth serial port for wireless devices like handheld plotters, tablets, and autopilots — no Wi-Fi required.

File Logger

Record every sentence to file for voyage logging, post-trip analysis, or replay. Auto-rotates at 50 MB with configurable retention.

Live Monitor

Real-time terminal with colour-coded sentence types, connection status dashboard, and per-source statistics at a glance.
