WiFi / Bluetooth

OpenNMC uses the Nagami onboard ESP32 for WiFi and Bluetooth.

Interfaces

Interface	Notes
WiFi	The factory-flash script checks for wlan0 after esp32_sdio is loaded
Bluetooth	The ESP32 stack is intended to expose a standard HCI device

Firmware

The ESP32 is provisioned as part of the OpenNMC software stack. The shipped image uses the esp-hosted package and flashes the SDIO-only firmware bundle from /var/firmware/espressif/esp32-sdio.

Usage

Wi-Fi is managed by NetworkManager, so you can use nmtui or nmcli after the initial console setup. Bluetooth uses the ESP32-provided HCI device and standard BlueZ tooling.

Hardware Note

The WiFi and Bluetooth antenna connector is RP-SMA and is connected to the Nagami ESP32. The front-panel label for this interface is WiFi/BT.
