Wi-Fi drivers
The nRF Connect SDK provides host Wi-Fi® drivers that implement the IEEE 802.11 protocol and integrate the Nordic Semiconductor Wi-Fi devices with the Zephyr networking stack. These devices are FullMAC devices, which means that the complete IEEE 802.11 MAC layer, including the MLME, runs on the device firmware rather than on the host. The host driver configures the device and transfers frames between the device and the networking stack.
The following sections describe the host drivers for each Nordic device series.
nRF70 Series
The nRF70 Series devices are Wi-Fi companion ICs that add Wi-Fi connectivity to Nordic Semiconductor System-on-Chips (SoCs), such as the nRF53, nRF54L, nRF54H, and nRF91 Series. The following pages describe the nRF70 Series Wi-Fi driver, its OS-agnostic portable implementation, and the low-level API.
nRF71 Series
The nRF71 Series is a standalone, highly integrated, low-power Wi-Fi 6 and Bluetooth® Low Energy combo System-on-Chip (SoC). Unlike the nRF70 Series companion IC, nRF71 Series devices integrate the Wi-Fi radio and the application processor in a single SoC. The host Wi-Fi driver runs on the nRF71 Series application processor. The following page describes the nRF71 Series driver and its firmware interface.
