[SOLVED] With Openplotter 0.9.0 AIS does not work - kste - 2017-02-16
I Raspberry pi 3 with Adafruit 10-DOF IMU and rtl usb dongle for ais.
With openplotter 0.8 AIS successfully works, with Openplotter 0.9.0 AIS does not work
I tried 3 different rtl dongle but no one works
Thanks for your help

Hello Sailoog, if you want to check I can give you the account for remote connection.

Do you use the latest github v0.9.0?
You can test AIS in terminal with:
rtl_fm -f 161975000 -p 0 -s 48k | aisdecoder -h 127.0.0.1 -p 12345 -a file -c mono -d -f /dev/stdin
-p (ppm) has to be adjusted

Do you run the RTL2838 from a powered hub? Some kind of power problem?
What does lsusb say?

Does gqrx work?
pi@openplotter:~/.config/gqrx-2.6-rpi3-1 $ ./run_gqrx.sh
RE: With Openplotter 0.9.0 AIS does not work - kste - 2017-02-23
gqrx starts, but I do not know if it works ... (I do not know this program)
OK Gqrx works, I see FM radio spectrum and sound waves.

Today I went on board:
- I turned off power and back on everything.
- I unplugged the sensor imu
- I repeated the test with a new microSD with a clean install.
- Diagnostic continues to not show the AIS sentences (nothing on system, nothing of opencpn of kplesk).
- If I off "AIS Reception" AIS the from terminal I see the strings:
pi@openplotter:~ $ rtl_fm -f 161975000 -p 0 -s 48k | aisdecoder -h 127.0.0.1 -p 1 -a file -c mono -d -f /dev/stdin

I understand the problem and solved!
In .kplex.conf configuration file in the system section must be added the voice address=localhost
This is missing in the files installed by openplotter.
Like this is ok:
[udp]
name=system
direction=in
address=localhost
port=10110
