## What it is
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
