Hi Roosmalen,
If you are using Boilerplate firmware you can't set different sampling rate in one Shimmer. You should use the higher frequence you need in your system. This is because is simpler manage just one sampling rate firmware side.

You can write your own firmware, based on boilerplate, with different sampling rate. :)

Best,
Edoardo

I'm trying to use 1 Shimmer sensor in Android for both the Acceleration and ECG 
data.
But I want a sampling rate of 100 for the ECG and 10 for the acceleration.
How can i specify that?
This is what I have now:

case SensorTypes.SENSOR_ACCEL|SensorTypes.SENSOR_ECG:     
sensorDevice.writeEnabledSensors(SensorTypes.SENSOR_ACCEL|SensorTypes.SENSOR_ECG);
        sensorDevice.writeSamplingRate(10);

        dataUri = AccelContentProvider.CONTENT_URI;
intentData = new Intent(Constants.INTENT_ACTION_PROVIDE_SENSOR_DATA_START);
intentData.addCategory(Constants.INTENT_CATEGORY_SENSOR_DATA_SUBSCRIBER);
intentData.putExtra("uri", "AccelContentProvider.CONTENT_URI");
intentData.putExtra("datatype", SensorTypes.SENSOR_ACCEL);
intentData.putExtra("uri", "EcgContentProvider.CONTENT_URI");
intentData.putExtra("datatype", SensorTypes.SENSOR_ECG);
sendBroadcast(intentData);

break;
