# qemu-esp32-wireless: ESP32 wireless hardware emulation

> qemu-esp32-wireless reconstructs ESP32 Wi-Fi and Bluetooth LE hardware behavior in QEMU to run stock ESP-IDF firmware and its wireless blobs. QEMU patches model radio events, 802.11 traffic and BLE connections; the repository also provides example firmware, capture tools and test scenarios. The author reports comparing wireless timing with ESP32 hardware over JTAG.

## Requirements & limits

- **Prerequisites:** Apply the patches to Espressif's QEMU fork and build qemu-system-xtensa; build example firmware with ESP-IDF.
- **Limits:** BLE connection establishment sometimes requires retries, and encrypted characteristic access after discovery times out.
- **License:** No licence stated on the project page.
