Error connecting to spectrum server

[rstremke]

I just installed rtlamr on a brand new installation of Debian on a Raspberry Pi. Everything went well, but when trying to run any rtlamr command, I get the following:

main.go:90: Error connecting to spectrum server: dial tcp 127.0.0.1:1234: connect: connection refused rcvr.Connect
main.(*Receiver).NewReceiver
/root/go/pkg/mod/github/.com/bemasher/rtlamr@v0.9.3/main.go:90
main.main
/root/go/pkg/mod/github/.com/bemasher/rtlamr@v0.9.3/main.go:313
runtime.main
/usr/local/go/src/runtime/proc.go:272
runtime.goexit
/usr/local/go/src/runtime/asm_arm.s:884

I've found a few other references to this type of error, but they seem to involve a Docker installation method, or a problem with a USB device becoming unavailable after time. I have not been able to successfully run this, yet.

Thanks in advance for any assistance.

Not at my computer, but pretty sure you need to start rtltcp firstI think the manual suggests running it in two separate shell windows--Nils Gokemeijer (Sent from iPhone)On Nov 11, 2024, at 5:37 PM, rstremke ***@***.***> wrote: I just installed rtlamr on a brand new installation of Debian on a Raspberry Pi.

I confirmed I have rtl_tcp running via a script. A systemctl status rtlsdr returns all green enabled/active (running) statuses. The call to rtlamr still returns the same error. By separate shell do you mean I should run rtl_tcp in zsh and rtlamr in bash - or something similar? Apologies, most of my unix experience is from about 20 years ago.

**Edit: installed zsh and switched to it. Ran the rtlamr command and still get the same error. rtl_tcp is running in bash.

That error for me happened when my docker container running rtlamr couldn't find my rtl_tcp server because the IP address changed. Try specifying the IP address of the machine where rtl_tcp is running explicitly rather than relying on the loopback address (127.0.0.1).
