M5 Nemo
Playful firmware for M5Stack devices: TV-B-Gone remote, Wi-Fi and Bluetooth beacon tests, and detectors for nearby attacks.
Chipnik catalog@chipnik-catalogM5 Nemo turns an M5Stack device into a pocket gadget for learning about radio: a TV-B-Gone style infrared remote, Wi-Fi and Bluetooth beacon tests, a captive portal demo, and hunters that warn about deauthentication and rogue access points nearby. Original project by n0xa on GitHub, GPL-2.0 or GPL-3.0 (Chipnik distributes it under GPL-3.0). Chipnik hosts the release binaries unchanged so you can flash them from the browser. For research on your own networks and devices.
The infrared remote uses the IR LED that the StickC Plus2 and the Cardputer already have.
Firmware files come from the v3.2.2 release.
