Software defined receiver for wireless M-Bus with RTL-SDR
rtl-wmbus is a software defined receiver for Wireless-M-Bus.
It is written in plain C and uses RTL-SDR to interface with RTL2832-based
hardware.
Wireless-M-Bus is the wireless version of M-Bus
("Meter-Bus", http://www.m-bus.com), which is an European standard for
remote reading of smart meters.
The primary purpose of rtl-wmbus is experimenting with digital signal
processing and software radio.
rtl-wmbus can be used on resource constrained devices such as Raspberry Pi Zero
or Raspberry PI B+ overclocked to 1GHz. Any Android based tablet will do
the same too.
rtl-wmbus provides:
- filtering
- FSK demodulating
- clock recovering
- mode T1 and mode C1 packet decoding
Paths come from the repository package-file index for the observed builds. They describe archive/package associations, not every file that will exist on a running system after maintainer scripts, alternatives, generated state, diversions, or installation choices.
Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
