Then try to calibrate normally using openplotter. If it works it will mean that your device was not in the list of supported devices: /etc/udev/rules.d/rtl-sdr.rules
SDR AIS available in OpenPlotter 2

Hi @Sailoog, can You tell me if I make my GPS USB Dongle work ( I make connection in Opencpn = TCP, localhost, 10110 and in Serial App = NMEA0183 > SignalK) and now I want to add my DVB-T SDR USB Dongle, do I have to add some other connection in Opencpn? Or that one I made will work for both devices?
Regards Przemek
It should work.
You should have just one connection in OpenCPN: localhost TCP 10110, because this is the connection to get NMEA 0183 data from Signal K. Then you should send all NMEA 0183 data to Signal K so using the serial app for the gps and the sdr app for the sdr device is the correct way.

Hello Saillog eventually you could add an Checkbox to the SDR-RTL App (daemon) to log the Stations on the Console? default: /usr/bin/rtl_ais -d 0 -p 0 -P 10110 logging: /usr/bin/rtl_ais -d 0 -p 0 -P 10110 -n and if you are working here, the App won´t remember the GSM & PPM Numbers, like your old 1.2 V. did. Great Work, stay well. Holger (2020-04-29, 11:21 AM)Sailoog Wrote: It should work. Hi, when I install openplotter in my ubuntu laptop I see only GPS (/dev/ttyACM1) in Serial app. I open SDR VHF app, make calibration and after all process openplotter add automatic connection to my signalK server. But I don't know it is working because in pleace where I live there's no water and ships. Can I check somehow it is working? Regards Przemek

Hello Przemek This is normal, only GPS is an serial Port. The SDR-RTL Communication goes per Network with some help on translating the internal Audiosignal to NMEA ASCII Strings. The normal RTL-SDR Sticks have no Serial Port. But there are other AIS-Receiver available, who do this, they have an Serial Port with the AIS Data. PS: I also use these Sticks from NOOELEC sudo systemctl status openplotter-rtl_ais.service * openplotter-rtl_ais.service - Decode AIS received by rtl-sdr and send as NMEA 0183 to UDP port Loaded: loaded (/etc/systemd/system/openplotter-rtl_ais.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2020-04-29 13:09:25 CEST; 1h 4min ago Main PID: 1686 (rtl_ais) Tasks: 4 (limit: 4915) Memory: 1.2M CGroup: /system.slice/openplotter-rtl_ais.service `-1686 /usr/bin/rtl_ais -d 0 -p 1 -P 10110 Apr 29 13:09:25 Wilhelmina rtl_ais[1686]: Output: 48000 Hz Apr 29 13:09:25 Wilhelmina rtl_ais[1686]: Detached kernel driver Apr 29 13:09:25 Wilhelmina rtl_ais[1686]: Found Rafael Micro R820T tuner Apr 29 13:09:26 Wilhelmina rtl_ais[1686]: Log NMEA sentences to console OFF Apr 29 13:09:26 Wilhelmina rtl_ais[1686]: AIS data will be sent to 127.0.0.1 port 10110 Apr 29 13:09:26 Wilhelmina rtl_ais[1686]: Tuner gain set to automatic.

Hello Przemek
for the GPS, you use also an ublox device like me. I had some issures with mine today, look here at the end for an solution: http://forum.openmarine.net/showthread.php?tid=1013 good look

I have to set everuyhing once again. Soon I will recive my LCD touch screen for Raspberry and I will check it on my balcony where I can catch gps signal. I will try Your solution then. Thanks.

YEAH, never change an running System! (Myself broke lots of Openplotters by updating to the latest BETA Versions & trying to keep them working again) But it improves the Stability. Good luck when the System is on Bord and happy Journeys with your Dad. Holger |
