## What is NMEAconnect?

NMEAconnect can connect to almost any NMEA source using TCP/UDP, BLE, internal/external GPS, Simulation or Logfile and act as an NMEA server/bridge via TCP/UDP.

With NMEAconnect you have:
∙ support of NMEA 0183, NMEA 2000, SignalK or MQTT data of almost any device
∙ a simple setup with preconfigured sources plus versatile configuration options
∙ all values ordered into clear 'Modules'
∙ a NMEA multiplexer, hub or switch
∙ a server/repeater to forward NMEA messages to other devices (most NMEA-WiFi gateways are accepting only one client)
∙ a server of the internal GPS Position as NMEA data to an external device
∙ a MQTT broker, client or gateway
∙ ‚unlimited‘ NMEA log (even when NMEAconnect is in background)
∙ nmeaconnect:// protocol to provide NMEA data e.g. to a Filemaker database
∙ background updates
∙ a visual indicator for NMEA activity
∙ Environments to handle different setups
∙ Message-Rules: Block, Gate Time and TalkerID for each NMEA sentence

### 5/5 — Does the job very well

*2022-11-15*

If you need to monitor NMEA messages, this is the app you need. It works perfectly well, and furthermore, the developer has been very helpful solving issues with incorrect NMEA messages that other similar apps treated as valid. Basic use is to check whether your device receives the NMEA sentences, and log them to a file for further examination. This allowed me to solve problems with navigation applications when their developers couldn’t figure the problem. Definitely worth the price! 

Be aware that there are other similar applications, but some will accept invalid messages, others will allow only TCP connection (mostly useless in most cases). Also be aware that only one application can receive broadcasted messages on a given port at a given time. If the app doesn’t work, check that another app isn’t using the chosen port. Typically, you can’t log the messages received by a navigation app running at the same time on the same device. If you need to do that, you’ll have to run the two apps on two different iPhones or iPads. I use the navigation app on my iPad and NMEA connect on my iPhone. That works perfectly.

### 5/5 — Gutes Backup für Bord-GPS

*2022-06-10*

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.

### 5/5 — Great for diagnosing NMEA networks

*2021-06-21*

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.

### 4/5 — Internal gps lacks accuracy

*2021-03-03*

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.

### 1/5 — Does not work!

*2019-11-19*

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

### 5/5 — Super Werkzeug!

*2015-03-01*

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

### 5/5 — Sehr nützliches Tool

*2014-05-22*

Ich bin selbst iOS-Entwickler und verwende die App um NMEA-Quellen in mySeaMap einzubauen. Durch die Verwendung des internen GPS und der Simulation ist das ganz einfach, auch wenn man keine echte NMEA-Hardware hat. Wünschenswert wäre noch, dass die App auch im Hintergrund weiterläuft, nicht nur für 3 Minuten. Unter iOS7 sollte das möglich sein.

## Frequently asked questions about NMEAconnect

### 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.
