BlueBM

The following Android apps are unpublished, but can be made available:

BlueNavtex1

If you are technical enough to be able to hang a serial (conventional) bluetooth adaptor on to a NasaMarine serial ouput Navtex receiver, even an old one, then this android app will accept a download wirelessly and display Navtex messages on tablet or phone in the same format as BlueNavtex2 and BlueNavtex3..

The app has all its functions working (December 2020), but needs a bit of optimisation. Email me if you are interested in checking this out. I am happy to advise on bluetooth adaptor connection. There are settings and download  transmisson speeds you would need to know.

BlueNavtex3

This is now (as at November 2020) a complete and publishable android app.  It is a development of BlueNavtex2, but with the added feature of being able to download all the messages from the Nasa Marine BT3 to a stored table, so you can review them later. The downside is the download time (3 to 5 minutes). If you want this, email me. If people like it and there is a demand, I may publish it, possibly at a small premium.

Navtex Companion

This a complete and functional android app. It lists all the Navtex stations I can find on the internet by NavArea, along with the Message Type codes, and the standard broadcast time allocation table.

I doubt the data will ever be fully up to date, but I can update it at intervals if users email me verifiable changes. I have now completed version 2 of the app which has the facility of downloading an updated table from my website. You can download the .apk file here with my compliments, but once you have checked it out, please let me know if you think it is useful to you.
