The C-based Firmware Patching Framework for Broadcom/Cypress WiFi Chip
...Nexmon is our C-based firmware patching framework for Broadcom/Cypress WiFi chips that enables you to write your own firmware patches, for example, to enable monitor mode with radiotap headers and frame injection. This repository mainly focuses on enabling monitor mode and frame injection on many chips. A real Wi-Fi jammer that allows to overlay ongoing frame transmissions with an arbitrary jamming signal. It uses the Wi-Fi chip as a Software-defined Radio to generate jamming signals. It allows using non-standard channels such as 80 MHz bandwidth in the 2.4 GHz bands. It allows to set of arbitrary transmission powers. It allows patching the D11 core's real-time MAC implementation. ...
