encode_21 not in source about ais HOT 7 CLOSED

Im having a hard time finding any reference to an encode_21 method. Could you point me to the file and line number you are seeing this on?

Edit: I found it in AIVDM_Encoder.py Which I have never used. Shouldn't be to hard to add encode_21. Perhaps I will look into it.

OK. Seemed strange that the option for AtoN was there but the encoding wasn't! :-)

Try this and let me know if it works for you: https://github.com/zhudsonSM/aistx/tree/msg21fix

Yes, seems to work and encode OK as verified by a few online decoders (eg http://www.aggsoft.com/ais-decoder.htm).
Thanks!

I created a pull request: #5
I do not think that trendmicro is maintaining this any more so it will probably stay unmerged

Hi all,

I was not maintaining this code until now, when I recently received few feature additions -- that I just committed. I will now take a look at the pull requests and most likely merge!

Thanks for this.

PS. As it normally happen in research labs, we often move forward when a research is done. That's why I don't allocate time to enhance or maintain code of completed projects. But I am more than happy to support contributors at any time: don't hesitate to contact me, better via email!
