About

This utility app acts as a server or bridge for NMEA data, connecting to various sources like TCP/UDP, BLE, and GPS. It organizes data into modules and can forward messages to other devices, acting as a multiplexer or repeater.

NMEA 0183, NMEA 2000, SignalK, MQTT support
TCP/UDP, BLE, internal/external GPS, Logfile connection
NMEA multiplexer, hub, and switch
Server/repeater for NMEA messages
Background updates and logging
Message filtering and rules

Gutes Backup für Bord-GPS

Sehr umfangreiches NMEA-Tool. Ich benutze es an Bord via Wifi mit einem NMEA-Multiplexer, u.a. zu Diagnosezwecken. Darüber hinaus ist es ein super Feature, die Positionsdaten des iPhone-GPS als NMEA via UDP zu senden (als Backupsystem für das Bord-GPS). Im Gegensatz zu einigen anderen Apps, die GPS-Daten über NMEA senden, kann man hier die Daten auch wirklich als korrekte UDP-Broadcasts senden.

Great for diagnosing NMEA networks

I paired this with a Yacht Devices NMEA 2000 WiFi gateway (YDWG-02) and can now see all the traffic on the NMEA 2000 (or SeaTalk NG) network. Either a dump of all the traffic or seeing the data organized by source and signal. For example, I can see that my chart plotter is not talking on the network (problem with chart plotter) and that my wind direction and wind speed are reasonable even though the wind display is out to lunch (need to fix the display, not the sensor). I can even record the data in the raw format and email it to myself for analysis later on.

Internal gps lacks accuracy

This is a great app, very configurable. However, when using the internal gps on iPhone, it only produces two nmea message types, and never gets beyond 2d fixes, which some applications need to work well. While it does stay running in the background, it appears to stall and give inconsistent readings at times.

Does not work!

Trying to add a source, but is crashing everytimes.
Maybe too old to work on iOS 13+

Super Werkzeug!

Habe mir die App geholt, um Vermessungstools zu testen. Klappt super, alles relativ intuitiv. Vielen Dank!

FAQ

What NMEA data formats does NMEAconnect support?

NMEAconnect supports NMEA 0183, NMEA 2000, SignalK, and MQTT data formats. This allows it to interface with a wide range of marine electronic devices.

How does NMEAconnect connect to data sources?

It can connect via TCP/UDP, Bluetooth Low Energy (BLE), internal or external GPS, simulation, or log files. It also supports direct connections to many specific devices listed on the developer's website.

Can NMEAconnect act as a server for other devices?

Yes, NMEAconnect can function as an NMEA server or repeater, forwarding NMEA messages to other devices. This is particularly useful as many NMEA-WiFi gateways only accept a single client connection.

Does NMEAconnect log NMEA data?

Yes, NMEAconnect offers 'unlimited' NMEA logging capabilities, even when the app is running in the background. This allows for continuous data recording for later analysis.

What are the 'Message-Rules' in NMEAconnect?

Message-Rules allow users to control NMEA sentences by blocking specific messages, setting gate times, and filtering by TalkerID. This provides fine-grained control over the data flow.

Is NMEAconnect compatible with iOS devices?

NMEAconnect is compatible with iPhone, iPad, and iPod devices. It can utilize the device's internal GPS and barometer for data.

How often is NMEAconnect updated?

The latest version, 2.11, was last updated on January 28, 2025. Updates typically occur to improve compatibility and add support for new devices or features.

Does NMEAconnect have ads?

No, NMEAconnect does not contain advertisements. As a paid application, it provides an ad-free experience for users.
