Scan/Copy

Scan and copy RF signals in ASK/OOK modulation. It will start with the default frequency (433Mhz, common for M5 RF433R and FS1000A modules).

Mode

Decode: tries to decode the signal with RCSwitch decoder RAW: Will display RAW signals obtained from RCSwitch library.

Filter

Code: On Decode mode, it will only display decoded signals. more reliable in noisy environments All: will capture Decoded and RAW signals

Replay

Send the last signal captured by Bruce.

Save

Stores the signal into ./BruceRF of your SD Card or LittleFS**

CC1101 only menu

Range

Choose the frequency to scan or a range to detect the frequency

Threshold

Choose the sensibility of the scanner. -60 to a more strict error frequency (more precise) -80 to a more broad frequency (greater error, less precise)

Record Raw

Records RAW signal using ESP32 RMT driver, displaying the raw signal obtained in a few seconds of capture. The recording will start once it detects a minimum signal on the input. If using CC1101, you can choose the frequency you want to record. In this function you can Save, and replay signals.

Custom SubGhz (limited compatibility)

Transmits signals stored in .sub files, they can be the ones saved by Bruce in the BruceRF folder or others downloaded from internet.

Spectrum Analysis

Displays waveform signals if RF frequencies are detected.

Squarewave Spectrum

When signals are detected, it displays a squarewave based on the timings of the signal.

Jammer Full

Starts a full square signal on the output, jamming the RF spectrum in the 433Mhz area, or in the RF Frequecy set in the Config Menu (if using CC1101)

Jammer Intermittent

Starts a PWM signal on the output, jamming the signal, not harming the transmitter, if listening to the frequency with a radio, yo´'ll be able to hear a "weeeoooooiiiiiioooooeeee" sound

Config

RF TX Pin and RF RX Pin

If using M5Stack, FS1000A or other single pin module to transmit the signal, here is where you can choose the pin

RF Module

M5 RF433T/R

M5 RF433T/R modules or unofficial modules.

CC1101

If you are using a StickCPlus (1.1 or 2), you will be presented to two options of CC1101

CC1101 (legacy)

This setup is designed to use only the CC1101 in the bus, using THIS setup

CC1101 (Shared SPI)

This setup is designed to share the SPI bus with the SD Card, but in this case you ned to add a transistor into the circuit, using THIS Setup

Supported Modules

Official Modules

  • M5Stack RF433R and RF433T

    • Frequency: Fixed at 433MHz
    • Modulation: Only ASK/OOK
    • Connection: Easier to connect

  • CC1101 SPI Module

    • Frequency Range: Supports multiple frequencies and modulations
    • Connection: More complicated, can be tested with exti/o2 from M5Stack

Unofficial Modules

RF-Pins

Note: Some modules may have poor range; modifying the antenna can improve performance.

Default Pins:

  • Tx = GROVE_SDA
  • Rx = GROVE_SCL

Unsupported/Not Working

  • HC-11
  • HC-12
  • LoRa modules

Replay Payloads Like Flipper!

Bruce can now send raw formats similar to those supported in this repository.

Methods to Transmit .sub Files:

  1. Via the Custom SubGhz app in the RF menu.
  2. Via the SDCard/LittleFS file manager in the Files menu.
  3. Via the WebUI by clicking the antenna-like button next to the file.
  4. Via a serial command, such as:
