RTL-SDR device selected regardless of input parameters #47

Hi!

First of all i have to say thank you for this awesome piece of software! I have been running AIS-receivers for 12 years and this summer i replaced both my hardware AIS receivers (True Heading AIS Carbon RX and a SR-161) at two locations with AIS-catcher after comparing them in parallell for a few weeks.

Having an issue with a Raspberry Pi 3B running one RTL-SDR device (for other stuff) and one Airspy HF+ for AIS.

I have had this running on another Raspberry with version 0.38 and 0.39 for five months straight, and for reasons i had to move the Airspy HF+ to this Raspberry Pi instead. Doing a git clone today, compiled it and got into trouble....

AIS-catcher seems to select the RTL-SDR dongle regardless of input parameters. As long as the RTL-SDR stick is connected it will be the device it starts with.

I have a systemd service file where all things are defined so nothing i know of changed.

I removed start-parameters one at the time but still, with only device type selection left, still goes for SDR-stick.

If i unplug the SDR-stick, then it goes for the Airspy

Any idea if i am doing anything wrong or perhaps a bug somewhere?

Hi, thanks for using the software!

If you type the command AIS-catcher -l it will list the available devices. Then you can start AIS-catcher either as:

AIS-catcher -d:x (whereby the x is the number in front of the AirSpy HF+)

or

AIS-catcher -d xxxxxx (whereby xxxxx is the serial number of the AirSpy HF+).

The latter approach is the best as the RPi might change the ordering of the SDRs and then you end up starting the RTL-SDR. Using the serial number to identify and activate the device is robust.

The parameter -gh sets the hardware parameters of the AirSpy HF but does not instruct AIS-catcher to use this device. The only way to select a device is the d switch.

In fact -gh without any parameters to set is not doing anything. So to use the AirSpy HF+ you use a combination of -gh and -d where the first can be left out if you are happy with the default parameters (which for the AirSpy HF likely is the case).

Can you get the AirSpy HF+ to start using the d-switch? Otherwise we need to dive a bit deeper.

Thanks and kind regards, Jasper

That did it. It was an error behind the keyboard :)

Thank you!
