Open iwikus opened 1 year ago

Hi, according to page https://revspace.nl/Msi2500SDR rtl_433 should be supported, but I can not get decoded any data:

Not sure if it is caused by warning in line [SoapySDR] SoapyMiri: CS16 format is untested! Is it possible to select different format for rtl_433? How?

Hm, I think rtl_433 used to work fine with SoapyMiri. I'm not sure. You're actually using SoapyMiri, which should be responsible for any conversions. While the CS16 format is supported, I'm not sure if I've implemented it correctly.

Anyway, as a workaround, I'd recommend using the rtl_tcp server built into my fork of SDRPlusPlus. Simply add the module and it will present a slice of the spectrum over TCP. Then you can use any rtl_tcp-compatible program: rtl_433 -d rtl_tcp:127.0.0.1:12500 -s 500k
