SDR++ Remote Control Module

Source: development/sdrpp/remote_control/README.md

remote_control is an OpenRoadCode SDR++ module for application/UI-level control that is not part of radio tuning itself.

Endpoint

127.0.0.1:4533

Responsibilities

The module controls SDR++ presentation/runtime features including:

  • Waterfall visibility
  • Band plan visibility
  • FFT peak hold
  • FFT/waterfall auto range
  • SDR++ theme selection

It deliberately does not own RF tuning, modes, bandwidth, RDS, or telemetry measurements.

ORC Service Split

:4532  Rigctl          radio/RF control and radio-specific data
:4533  remote_control SDR++ application/UI control
:4534  telemetry      read-only runtime measurements

Python Client

ORC accesses this protocol through:

protocols/sdrpp_remote_control/

Application-facing behavior lives under controllers/sdr, keeping socket/protocol details out of frontends.

Development Test Server

A Python test server is included for developing ORC without a live SDR++ module:

python development/sdrpp/remote_control/test_server.py

The test server should mirror only the :4533 control protocol. Telemetry commands belong exclusively to the telemetry service on :4534.
