Hi,
I am using SDR-AIS now for some time and it works perfect.
I am trying to use an extra RTL-SDR dongle for recording HAMradio automatically. Because it also uses RTL_fm, like SDR_ais does, it shares the same RTL dongle.
What I am trying to accomplish is that RTL_test sees both dongles, however one is always in use by SDR-AIS.
I realize drivers can be blacklisted in the /etc/modprobe.d directory, however I am not sure what effect this will have on my currently working SDR-AIS.
Also, I know when unchecking the SDR-AIS in Openplotter will unblock device #0 and all works well.
However I don't want to do this every time, because while sailing I want my AIS to keep working while I record things in HAM or Marine frequencies that uses another type of antenna. That's why I thought connecting an extra separate dongle would do the trick.
My question is as follows:
- Is there a way to assign device #2 to SDR-AIS only? Or does this need to be done in RTL_fm? If so, how?
Maybe another way of asking is, can rtl_fm run two dongles or two instances at a time for separate dongles.
