The latest Navionics has this "SonarCharts Live" feature for creating bathymetric charts from your sounder when connected to one of their approved partner products. I mailed Navionics to ask how to send data to the app generically so that those with other serial to wifi solutions could enjoy the benefits of this wonderful new feature. Actually I have no interest whatsoever in creating bathymetric charts (although I'm quite keen on the word "bathymetric") but was curious to know how it worked. Sorry they said but it's super-secret-squirrel-very-compilcated-stuff and we won't let on.
So I had to waste a large chunk of thursday with a raspberry pi and my recently updated android Navionics app experimenting. Here's how to get SonarCharts Live working with your home-brew serial-to-wifi kit:

I suspect that the iOS version *may* offer another option (based on bonjour) but need to lay my hands on an iThing with Navionics to test that out.
The interesting thing is that Navionics *seems* to be accepting GPS info as well as depth info when provided this way which may be of interest to those who bought the duff iPad without GPS.
On a different note, in snooping network traffic to see what this app was doing I noted that on startup before you hit "OK" it eats up a load of bandwidth on contacting brand/marketing/analytics companies (markmonitor, flurry) as well as what I presume are its own (AWS-hosted) servers. So presumably it's making full use of the outrageous permissions to read your personal contacts and info that the app demands....
