Hi

Does live data via nmea allow bottom hardness to appear on reef master.

Just looking for an on water solution in new areas I will be mapping and fishing at the same time.

NMEA provides position and depth only - there is no sonar information as such. Therefore it is not possible to get bottom composition information in real time.

Thanks Matt - Lowrance distributes sonar data over wifi as below

This document details the GoFree web interface provided by Navico Multifunctional Displays ( MFD ). The GoFree web interface is designed to allow developers to create web pages and applications that use data from the Navico system. Additionally the web interface can be used to change settings on the Navico system and control some functions.

The GoFree web interface is provided by an HTTP server and a WebSocket server.

The WebSocket server is used to bi-directionally send data between the Client (Web Browser, IPad App, PC Application, etc) and a selected Navico device. The WebSocket data is encoded in simple JSON strings, which are very easy to work with on the client side.


Would be a lot of effort to program reefmaster to connect to and provide mapping functionality live?

I code in iOS swift as a hobby at the moment and can grab the data easily enough but don't have the time to,work out how to draw with the data.

Are the position and depth the only data that can be shown on live data ? We can't see a live sidescan transect ?
