ESP32-C6 Wi-Fi 6 dashboard (OLED)

The RISC-V ESP32-C6 boots its real 802.11ax station stack, scans the virtual ether, joins BreadboardNet and leases an address over DHCP, then renders the live link (SSID, IP, channel, RSSI) to an OLED on the C6 pins (SDA G23, SCL G22). Open the 📡 Sniffer to watch every frame, and click the board to inspect all three of its radios: Wi-Fi, Bluetooth LE and the 802.15.4 MAC that Thread and Zigbee share.
