Things people build with this

USE CASE 1

Flash pre-built firmware onto an ESP32 board to get a portable wireless security testing tool without writing any code.

USE CASE 2

Monitor nearby WiFi and Bluetooth activity to detect unusual or suspicious wireless signals in your environment.

USE CASE 3

Modify the C++ source code to add custom wireless probing or monitoring features to your own ESP32 device.

USE CASE 4

Purchase the ready-made hardware unit for a no-assembly security research tool you can carry in a pocket.

Requires compatible ESP32 hardware, flashing the pre-built firmware is straightforward but building from source requires the Arduino IDE or PlatformIO toolchain.

Open-source license, the explanation does not specify which one.

In plain English

ESP32 Marauder is firmware for the ESP32 microcontroller that provides a set of WiFi and Bluetooth testing tools in one package. The ESP32 is a small, inexpensive chip commonly used in hobby electronics and Internet of Things devices, and this project turns one into a portable tool for probing wireless networks and Bluetooth signals. The README describes the project as a suite of offensive and defensive tools for WiFi and Bluetooth, aimed at security testing. Offensive in this context refers to tools used to test how networks respond to certain kinds of wireless probes, while defensive tools help detect or monitor wireless activity around you. Because this README is brief, the full feature list and setup instructions live in a separate project wiki linked from the repository page. To get started, you download a pre-built firmware release from the releases page and flash it to compatible ESP32 hardware. For those who want to build the firmware themselves or modify it, the source code is written in C++ and is available in this repository. The project also sells a dedicated hardware unit through the author's website, so you can purchase a ready-made device rather than sourcing and assembling components yourself. The README is short and intentionally points outward to the wiki for any deeper details. If you are evaluating this tool, the wiki is the right place to understand what individual features do and how to use them responsibly. The project is licensed under an open-source license and has attracted a large number of users given its focus on accessible wireless security tooling for hobbyist hardware.

Copy-paste prompts

Prompt 1

I have an ESP32 development board and want to flash the latest ESP32 Marauder firmware. Walk me through downloading the release binary and flashing it using esptool.py from the command line.

Prompt 2

I want to add a new WiFi scanning menu option to ESP32 Marauder. I know C++. Show me where in the project structure to add the new menu entry and the basic code skeleton for a scanning function.

Prompt 3

Explain what the defensive monitoring tools in ESP32 Marauder do and how I would use them to check whether there are rogue access points or unexpected Bluetooth devices near me.

Prompt 4

I'm building a custom security device based on ESP32 Marauder firmware. Help me identify which source files I can safely remove to strip the project down to WiFi-only features and reduce the binary size.
