esp32-80211-tx | Send arbitrary IEEE 802.11 frames

esp32-80211-tx is a C library typically used in Internet of Things (IoT), Arduino applications. esp32-80211-tx has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Sending arbitrary IEEE 802.11 frames can be useful in various ways, e.g. for mesh networking, unidirectional long-distance communication or low-overhead data transmission. It can, however, be abused for spamming large numbers of invalid SSIDs, jamming WiFi networks or sending deauthentication frames in order to sniff SSIDs of hidden wireless networks. Please be advised that such usage is morally doubtful at best and illegal at worst. Use this at your own risk. Espressif have now created the esp_wifi_80211_tx API, making esp32free80211 obsolete. The new function is thoroughly documented in the API guide. Since at the time of writing not a lot of sample code using esp_wifi_80211_tx exists and many developers wanting to send arbitrary data with their ESP32s end up using esp32free80211 with an outdated esp-idf version, I want to hereby provide some more up-to-date sample code for esp_wifi_80211_tx.
