rtl_fm no udp socket

[rfamp]

Hi, thanks for your amazing wrtite up! But when running doppler.py I get the error
ConnectionRefusedError: [Errno 111] Connection refused
Do I need rtl_udp to use it or do I have a wrong version of rtl-sdr? My current version is 0.6.1

Regards

Hi Joshua

So rtl_fm must be running before you start doppler.py.
When you run rtl_fm you should see an output line like this;

Main socket started! :-) Tuning enabled on UDP/6020 

If that number is different for you, it should be a matter of changing it within the code for doppler.py and then it will work okay.

Hi, thank you for your help. As it turned out, the rtl-sdr package in the raspbian repo seems to be different to the one which is available on plain debian. I'll investigate which version is newer, I presume the raspbian one.
And thank you again for this repo!
