+## ESP32 (NINA)
+
+Go Bluetooth has bare metal support for boards that include a separate ESP32 Bluetooth Low Energy radio co-processor. The ESP32 must be running the Arduino or Adafruit `nina_fw` firmware.

+See https://github.com/arduino/nina-fw for more information.

 ## API stability
 
 **The API is not stable!** Because many features are not yet implemented and some platforms (e.g. Windows and macOS) are not yet fully supported, it's hard to say what a good API will be. Therefore, if you want stability you should pick a particular git commit and use that. Go modules can be useful for this purpose.
