Hi @lann , I have been using your test project but i am facing an issue. I cant figure out how to read float values being sent by the RFduino to the android application. I have tried Floatbuffer, float.parse string, even the HEX helper but all in vain . From what i understand your code gives us a way to get the recieved data (initially in the form of bytes) in the form of a string or convert it into HEX values. but it would be extremely helpfull if you can let me know how to solve this problem

Turn on GPS and it will work again.

The app should be updated for Android 6 (M) to request permission ACCESS_COARSE_LOCATION if the app is running on Android 6.

When I start the application I find my device by scan button, when I try to connect nothing happens. Only state of TextView Disconncted changes to Connecting...

I also downloaded the apk. from: http://www.rfduino.com/product/rfduino-android-application/ and funny thing is that if I connect to RFduino there I also get data in my application. So it looks that is listening to data, but it won't start connection on it's own.

I am using Nesxus 5.

I had put Log.v inside RFduinoService initialize(), but nothing happens.

Hi @lann i am gonna update my problem statement it seemed a bit vague last time.
Code in RFDUINO so that everytime i send a value it sends me back the float value 2.34

include <RFduinoBLE.h>

void setup() {
RFduinoBLE.advertisementData = "ledbtn";
RFduinoBLE.begin();
}
void loop() {
}
void RFduinoBLE_onReceive(char *data, int len)
{
RFduinoBLE.send(2.34);
}

. when i try to do
byte[] ff = intent.getByteArrayExtra(RFduinoService.EXTRA_DATA);
Float.parseFloat(HexAsciiHelper.bytesToAsciiMaybe(ff))
i get the following errors

can you help me please?????

Hey this isn't an issue, just a general question.

In the RFduinoService file, how do you add the Descriptor to the UUID_CLIENT_CONFIGURATION characteristic so that the following line doesn't return Null?

BluetoothGattDescriptor receiveConfigDescriptor = receiveCharacteristic.getDescriptor(UUID_CLIENT_CONFIGURATION);

I see line 72 with:
public final static UUID UUID_CLIENT_CONFIGURATION = BluetoothHelper.sixteenBitUuid(0x2902);

I'm working with another Bluetooth module: http://www.microchip.com/wwwproducts/Devices.aspx?product=RN4020

And I can't seem to find a way to set a Descriptor on a Private Characteristic.

Thanks for any help.

I am a new Android Programmer. I want to display the received data in an application through BLE. @lann I've just downloaded your app and have synced it with Gradle in my Android Studio. But the values displayed after received data are only the first 9 values among the ones I sent from RFDuino. However, I can see the all of values in Serial Monitor of RFDuino. Is your app supposed to display the first 9 values only? Could you please look into this?
Many thanks.

Hi @lann ,

Great work on the Android app, i build your example app and tried to send the value like 2, 180 in pure text, my servo seems does not move, have you encountered something similar? Thanks
