+# esp-hosted driver
+
+This is a MicroPython driver for the Espressif
+[esp_hosted](https://github.com/espressif/esp-hosted/#readme) communications
+coprocessor, which allows creating a Wi-Fi and/or Bluetooth interface from
+MicroPython to a separate connected ESP32 compatible device running the
+`esp_hosted` firmware.
+
+## Building
+
+Enable this driver by setting `MICROPY_PY_NETWORK_ESP_HOSTED` to 1 in your
+Makefile. If `MICROPY_PY_BLUETOOTH` is set then the Bluetooth host driver will
+also be built.
+
+In addition to normal MicroPython build requirements, building this driver
+requires the [protocol buffer
+compiler](https://github.com/protocolbuffers/protobuf#protobuf-compiler-installation)
+(protoc) to be installed.
+
+On Debian/Ubuntu, it can be installed by running:
+
+```
+sudo apt-get install protobuf-compiler
+```
