The RFduino LED On/Off shows how to send data from the app to RFduino. The app uses device.writeDataArray and the RFduino uses RFduinoBLE_onReceive(char *data, int len).

Now I want to send data to the app. I guess the RFduino can use RFduinoBLE.send(). But I do not know how the app can receive this.

This guy can recieve some data. So in short, device.enableNotification('00002221-0000-1000-8000-00805f9b34fb', ...) should work.

I found the solution here: https://evothings.com/forum/viewtopic.php?t=1383
