ESP-Hosted is an open-source solution that lets Espressif SoCs like the ESP32 act as wireless communication co-processors, adding Wi-Fi and Bluetooth/BLE to external host systems over SPI, SDIO, or UART. It ships in variants targeting Linux hosts (native cfg80211 or RPC-based control) and resource-constrained MCUs.

Use cases

• add wifi to a linux single-board computer via esp32
• use esp32 as a bluetooth ble co-processor over spi
• give an stm32 microcontroller wifi connectivity
• share one ip address between host mcu and esp32
• keep wifi connection alive while host sleeps
• integrate esp32 wireless into embedded linux with networkmanager

When to choose

• your host device (Linux or MCU) lacks Wi-Fi/BT and you want to add it with an ESP32 module
• you need standard Linux wireless integration via cfg80211/wpa_supplicant
• you need low-power operation where the ESP maintains connectivity while the host sleeps

When to avoid

• your host already has native Wi-Fi/BT hardware
• you need Wi-Fi 6/6E or features beyond 802.11 b/g/n/ax
• you want a self-contained wireless solution without an external co-processor
