+# Simple TTS to A2DP
+
+This is just an adaptation of the [streams-simple_tts-i2s example](https://github.com/pschatzmann/arduino-audio-tools/tree/main/examples/examples-tts/streams-simple_tts-i2s) where the output stream has been replaced with a A2DPStream.
+
+So the output goes to a Bluetooth Speaker! 
+
+More examples can be found at https://github.com/pschatzmann/arduino-simple-tts/tree/main/examples
+
+Because we need a lot of progmem, do not forget to set the partition scheme to Huge APP!
+
+### Dependencies

+
+
+A word of warning: The A2DP output has it's challenges, so I do not recommend this as your first sketch.
