Nexmon is a suite of operational tools designed for firmware patching, ROM extraction, frame injection, and enabling monitor mode on wireless hardware. It provides utilities to modify wireless chip firmware to unlock low-level hardware capabilities not supported by official drivers.
The project enables the activation of monitor mode for capturing raw network packets with radiotap headers and allows for the transmission of custom-crafted wireless frames. It includes tools for dumping the read-only memory of wireless chips to facilitate reverse engineering and analysis of hardware behavior.
The software covers hardware target identification and revision matching to ensure firmware patches are compatible with specific chips. It also provides utilities for binary patch generation and the compilation of tools used to process hardware firmware modifications.
