Renesas RF Master

Configure and run RF PHY transmitter and receiver test operations on supported Renesas devices through a guided VS Code extension UI.

Overview

The Renesas RF Master extension helps validation and connectivity teams:

• Connect to target devices over serial from inside VS Code
• Configure test parameters such as channel, payload, data rate, mode, and TX power
• Start and stop RF test procedures using predefined HCI commands
• Monitor command/reply activity in the UI log window
• Query device firmware version and export captured session data

The extension is designed for repeatable lab workflows where command traceability and predictable start/stop behavior matter.

Features

Device Connectivity

• Automatic serial port discovery
• Connect and disconnect controls from the extension UI
• Connection-state updates and board status indicators

RF Test Configuration

• Predefined command profiles for TX and RX testing
• Configurable fields depending on selected command:
  • Frequency/channel
  • Payload pattern
  • Packet length
  • Data rate
  • TX power
  • Enhanced test fields (mode, packet count, interval, hopping range)

Command Execution and Validation

• Start sequence always includes a reset command before selected test command(s)
• Stop flow determined by the active command profile
• Response-prefix validation for supported HCI events
• Timeout handling with user-visible error notifications

Logging and Export

• Command and response hex trace in the UI log window
• Session export to JSON from backend
• Integrated user manual available in extension UI

Getting Started

Installation

1. Install the extension from your internal distribution channel or VSIX package
2. Connect a supported Renesas board over USB/serial
3. Open the RF Master command from the Command Palette

Quick Start (5 Minutes)

1. Open the extension

   • Press Ctrl+Shift+P
   • Run RF Master

2. Connect the device

   • Open the Device panel
   • Select the COM port
   • Click Connect

3. Configure a test

   • Open the Configuration panel
   • Select a command profile (TX or RX)
   • Adjust required fields (frequency, payload, data rate, and so on)

4. Run and monitor

   • Click Start
   • Watch Send and Receive hex traces in the status/log area

5. Check results

   • Check receive results for receive tests
   • Click the Εrrors button to check for any received errors

6. Stop and export

   • Click Stop
   • Export session data when needed

Commands

• Start Server: Starts backend HTTP and WebSocket services
• Stop Server: Stops backend services and releases the port
• Show UI: Opens the RF Master webview
• RF Master: Starts server and opens UI in one step

Troubleshooting

• No COM ports listed

  • Check USB cable, board power, and serial driver installation

• Connection fails or drops

  • Ensure no other tool is using the same COM port
  • Reconnect the device and retry

• Start command times out

  • Verify board firmware and test mode compatibility
  • Unplug/replug as prompted, then reconnect from the extension

• UI opens but no backend communication

  • Confirm server started successfully in allowed port range
  • Restart the Extension Development Host or reload VS Code window

Known Limitations

• Serial-only RF command execution path in desktop mode
• Command response validation is prefix-based and assumes expected firmware behavior
• Some command/stop combinations depend on mapping tables and may require firmware-aligned profiles
• Port range conflicts (3050-3150) can prevent backend startup
