install: cannot stat 'rtl_ais': No such file or directory #103

[galacticfr]

could you tell me where I can get that file? I tried running rtl_ais.c and rtl_ais.h but none of them worked

Hi

rtl_ais.c and rtl_ais.h are source files, you need the executable file in order to work. Please tell us which OS you are using so we can give you some guides.

Regards, David

I was trying to run it on window. I couldn't find rtl_ais.exe When I ran it on linux, I could not access port 10110

[dgiardini]

On windows seems to be ok, use the "-n" switch so you can see any incoming sentences.

On Linux, may be the port is in use, you can try using another one (" -P 10120 " for example). Use "-n" too.

Don't forget to set the ppm correctly to match the dongle error, you won't see any incoming data otherwise

I still have the same issue on linux. I tried different ports but none of them worked. I also tried different browsers

[dgiardini]

Your problem is not the ports, is the ppm, you are not specifying anyone, and that mostly doesn't work.

Look at the README file on github, at known issues: https://github.com/dgiardini/rtl-ais?tab=readme-ov-file#known-issues There are some guidelines there.

You can also google "rtr-sdr calibration"; you'll find a lot Of results, look for something easy for you.

As a result of the calibration, you'll get a number, that is the error of your RTL-SDR device in parts per million (aka ppm). You must pass this number as a parameter to the program using "-p ". The ppm is specific to the dongle, so you can use it on Linux, Windows, even other computers, always with the same dongle.

Good luck ! David
