BlueBeacon
Bluetooth Low Energy proximity beacon
OTA firmware upgrade
Over the air (OTA) firmware upgrade can be performed on BlueBeacon beacons (all models
excluding USB) using most recent iOS devices.
The example in this tutorial has been done using an iPad Mini running iOS 7.1.2. The screenshots
may vary slightly if you are using another version of Apple's mobile operating system or another
device.
Note: It is strongly suggested to implement the procedure one beacon at a time.
1. Install nRF Toolbox
The first step to enable DFU (Device Firmware Update) support on your iOS device is to install an
application named nRF Toolbox from Nordic Semiconductor.

2. Adding Custom Firmware
Before you can transfer our custom firmware to the BlueBeacon beacon, you need to copy the .zip
(or the .hex) file over to iPad, which requires to connect the iPad to your computer and load up
iTunes.
With the iPad connected to your computer and iTunes open, click the iPad icon in the top-righthand corner:
Once the iPad has been selected, select the Apps tab at the top and scroll down a bit. You should
see a section called File Sharing, as below.
Select the nRF Toolbox icon on the left-hand side, and then click the "Add..." button which will
give you a file selection dialogue box, as shown below.

BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
Select the appropriate .zip (or .hex) file that contains your firmware (note: in the specific example
shown in the following figures the name of the file is blemodule_s110_xxaa.hex, but the procedure
is the same).
The name of the files are shown in the following table.
Firmware version
File name
iBeacon
bluebeacon-v4.0.zip
Eddystone
eddystone-v4.0.zip
Note: *.zip files do not need to be unzip.
Then, click the 'Add' button, and the file should be added to the nRF Toolbox Documents list, and
shown below.
Now sync the iPad with your computer using the Sync button in the bottom right-hand corner of
iTunes, and the .zip (or .hex) file should be transferred to the nRF Toolbox app on your iOS device.

3. Using DFU in nRF Toolbox
Once you've installed the nRF Toolbox application and have it open you should see the following
main menu.

BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
Tap the DFU icon to load the DFU app, which is what you will be using to transfer new firmware to
the BlueBeacon beacon over the air.

4. Transferring the Firmware via BLE
Having the custom firmware image(s) on your iOS device, you can transfer one of them over the
air.
Into the nRF Toolbox application, open the DFU home page and click the Select File label shown
in the image below.
6/16
BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
This will bring up the following file selection dialogue box by default, listing some pre-installed
firmware images from Nordic Semiconductors:

Tel. +39 344 2030929, Fax +39 0577 043101
Click the User Files icon in the image above, which should show us any custom firmware files
have transferred via iTunes, as decribed earlier in this page.
Note: The filename used here may be different than the production firmware images or
future updates provided by BlueUp.

BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
Select the appropriate firmware image by clicking on it, which will bring you back to the DFU
homepage with some basic information about the .zip (or .hex) file will be displayed.
9/16
BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
Take note of the field that says 'Type: Required'. This means that you haven't specified what type
of code is encoded in the .zip (or .hex) file (user code, an update to the SoftDevice or an update to
the DFU bootloader, all of which can be updated over the air).
Next click the Select File Type label, and indicate that this is application code, as shown below.
Note: be very careful to only select APPLICATION in this dialogue or you can corrupt the
BlueBeacon flash memory contents!
This will send you back to the DFU home page where the Type field will have been updated to
application, and you are almost ready to transfer our firmware image.

5. Put the BlueBeacon in DFU Mode
Next you need to put the BlueBeacon beacon in DFU mode.
Note: make sure the beacon battery is not running low (less than 15%), otherwise replace it
with a new battery.
To put the BlueBeacon beacon in DFU mode, you need to:
1. (only if password access is enable, otherwise go to step 2) Using BlueBeacon Tool app,
from BlueUp, connect to the BlueBeacon beacon, inserting the required password. In the
Device Security page, disable password and disconnect.
Note: consider that, if you will enable the password again, the password will restart from
default value, 00000000.
2. Connect to the BlueBeacon beacon with a standard BLE app (you can use LightBlue app)
3. Select the characteristic with UUID
83362019-4D55-445B-B374-D53DB987EAD8
contained in the service with UUID
83361900-4D55-445B-B374-D53DB987EAD8

4. Write the hex value 1 (0x01) in the characteristic.
5. Disconnect from the BlueBeacon beacon. The beacon remains in DFU mode for 1 minute,
after that it restarts with the loaded firmware).

6. Connecting to the DFU Service
With the BlueBeacon beacon in DFU mode, you can now connect to it.
Click the Select Device button at the bottom of the DFU application on the iPad, which should
bring up the following dialogue box.
The name may be different from the one in the screenshot, where the name is DfuTarg. The
BlueBeacon beacon in DFU mode will advertise itself as DfuTarg or BlueUp-YY-XXXXXX (where
YY is the model and XXXXXX the serial number). Select this target by clicking on the entry in the
list.
Note: because of the way iOS caches beacon data, the beacon may be advertised as UART
or whatever custom name you set up. If that is the case you need to clear the cache by
enabling and then disabling Bluetooth on your iOS device. This is unfortunately something
outside the application level, and you can't reset Bluetooth inside an app yorrselves.
13/16
BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
This should enable the Upload label, as shown below.
14/16
BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
Click the Upload label to start transferring the file over the air, and you will be updated on the file
progress via a simple progress bar.
Note: If you encounter any problems with DfuTarg disconnecting or the Upload label not
being enabled, trying enabling and then disabling Bluetooth on your device, which will reset
the Bluetooth stack.

BlueUp S.r.l.s.
Tel. +39 344 2030929, Fax +39 0577 043101
Once the upload process is complete, you should see the following dialogue box, saying that the
transfer is finished, and you can reset your beacon (power-cycling it by removing and inserting
again the battery) to start executing the new firmware.
Note: the file size shown in this dialogue is the actually size of the firmware, whereas the
.hex (or .zip) file size may be much larger due to the file encoding and extra information
contained.
Congrats: firmware is now updated!
Note: because of the way iOS caches beacon data, iOS app will show you inconsistent
information (wrong beacon name, parameters, services and/or chars). You need to clear the
cache by enabling and then disabling Bluetooth on your iOS device.
