No data on my radar

[betko]

Hi.

I have Pi 4 with already sharing data to FR24 and i tried to the same for RB.
But it shows me that status is: "No data". Any idea how to check what is wrong and how to fix it?

Kind regards

While waiting on someone with knowledge of Pi's have a read here https://forum.radarbox24.com/index.php?topic=10201.msg187831#msg187831

Thanks, I followed these steps, but it looks like something is working just fine.

Looks like you are using PI24 image.
If this is the case, go to following page:

IP-of-Pi:8754/settings.html

In the field Process Arguments, add --net
Save settings, Restart fr24feed software.

Please see attached Screenshot below.

It worked, thank you.

EXPLANATION:

The RB24 feeder requires beast data on port 30005.

In Pi24 image, the pre-installed dump1090-mutability does not use default settings. FR24 feeder configures it to custom settings, which included blocking all default data input/output ports. As a result the output data at port 30005 is not available, and rbfeeder starts complaining "no data".

The blocked ports get opened when in FR24 feeder settings, in the field "Process arguments" a parameter --net is added.

You will note that there are two more parameters there
--gain -10, which sets gain of dongle (-10 is a special value, sets gain to 55 dB). Instead of -10, values between 0 and 50 are accepted. Any negetive value sets the gain to Zero (except -10 which is special case as explained above).

--lat xx.xxxx --lon yy.yyyy

This is latitude and longitude of receiver (use actual values in place of xx.xxxx and yy.yyyy). When latitude & longitude are added, the dump1090 map (ip-of-pi/dump1090/gmap.html) starts showning station marker and 3 concentric circles, centered at the station marker with radius 100nm, 150nm and 200nm. These circles are called range circles.

Thanks for the info abcd567 I am sure your explanation will come in very useful over time
