B. HAN-FUN Protocol (Downloadable from www.ulealliance.org)
1.2 Target Audience
The Starter Kit and this User’s Manual are targeting those customers familiar with running IoT
applications on a particular microcontroller (with a spare UART Interface!) and now are interested in
adding ULE wireless connectivity capability via the DHAN module. That said, the DHAN module
can be used for standalone (single-processor) applications and also can interface with an external
microcontroller via I2C or SPI interfaces. If any of these use cases interest you, please don’t hesitate to
contact DSP Group at the link shown below. “Ditto”for those interested in developing new ULE
Controller or Gateway devices. We can get you started with these applications as well!

1.3 Starter Kit Basics: A bit about DECT-ULE
DECT-ULE uses a star topology. Each DECT-ULE system contains only one device at the hub
of the star. This hub is typically the gateway to the WAN. In DECT cordless this hub is called the
Base Station. In the IoT context, the hub is called a ULE Controller. The points of the star are
traditional DECT cordless handsets and ULE Nodes or Devices –they can be integrated into a single
system. Thousands of ULE Devices can be associated with a single ULE Controller.
This Starter Kit incorporates a ULE Controller (BS Device) and a ULE Node (Device). The ULE
Controller includes a graphical interface for control and status reporting. It does not provide a means
to connect to the WAN. The Starter Kit promotes development of ULE Node applications per the
ULE Standard. Once completed and certified, your ULE Node can operate in any setting within range
of a certified ULE Controller. The ULE Controller is a common element in many gateways and over-
the-top boxes that populate our homes and offices.

1.4 Starter Kit Hardware
1.4.1 DHX91 EVB (= ULE Node)
The DHX91 EVB includes a DHAN Module (a custom version with printed antenna), several push
buttons, LEDs and access to vital IO pins that facilitate simple application emulation. The EVB can
be powered using the AC transformer outputting 5V (supplied with the Kit) or using a CR123A
battery. The EVB is delivered configured for this latter case. See the jumper configuration below for
both cases. It is suggested to initially power up the EVB with a 3V power supply clipped to the
battery holder to get feedback regarding the current drain.
The EVB can function as a standalone demo device (Step 1 below) or as a development tool to be
interfaced via RS232 to a PC (Step 2 below) or via UART to an external controller (Step 3 below).

1.4.2 DCX81 CMBS UART (= ULE Controller)
This platform includes the DCX81 CMBS Module mounted on a ULE Controller motherboard. It is
powered by the AC transformer supplied with the Kit. The Kit includes 2 antennas which are threaded
on to the SMA connectors, and positioned as shown in the photo below. The connection between the
Controller RS232 (UART I/F) connector and the PC USB port is also shown below.
The driver for the ST Lab adaptor (included in the Kit) usually loads on its own when it is plugged
into the PC. If not, it can be copied from the CD included in the Kit. Once the driver is loaded you
should be able to see a COM port opened in your PC Device Manager. You should note the COM port
value as you will need it to run the DSPG Test Application SW which you have downloaded.

2. Get your application up and running with ULE
Working through the steps below will enable the User to get an ULE Node application with basic
ULE connectivity up and running. This section provides an overview of the 3 steps, with following
sections elaborating Steps 1 and 2.

Here the ULE Node application is running on the PC using the VAR simulator you have downloaded.
(Note: Both sides of the link can run on the same computer). In this setup the User will learn how to:
Install and run VAR simulator on the Node side and the Controller GUI simulator on the
Controller side
Register the ULE Node, modify the operating frequency to comply with local regulations
Use the VAR simulator to trigger events and send maintenance messages (=Keep Alive) that
can be monitored at the Controller GUI
Copy the basic transactions at the CMND I/F so that they can easily be transplanted from the
simulator to the code running on the User’s application MCU.

The User designs an application board which integrates a favorite MCU, sensors/switches, the DHAN
module and a 2GHz antenna. Prior to designing this application board, the User should discuss
application needs and constraints with DSP Group to insure that the application schematic is optimal
as well as receiving the SW training and detailed documentation needed to create an full-fledged
application.

3. Getting the ULE Controller Up and Running
After connecting the ULE Controller (= DCX81 CMBS UART) as depicted in a previous section (and
confirming via your Device Manager that a new COM port is up and running!), you should run the
DSPG Test Application executable you have downloaded. The window below will pop up and you
should enter the appropriate value:
A Graphical User Interface will pop up as below and the log window should indicate that the
initialization was successfully completed (“CMBS Init Done!).
The log window shown above is an abbreviated version of the incoming/outgoing flow of information
at the CMBS UART Interface. A more detailed (message) log is recorded in a file that can be opened
from the button indicated above. This file is located in the same directory as the DSPG Test
Application.exe file.
Click on the “Open HAN Window” button in the lower right and note that a “Smoke” device is
registered to your Controller, as shown below. This is because the EVB ULE Node in your Starter Kit
has already been registered to the ULE Controller and has been programmed as a Smoke device. A bit
later you will delete this registration and can run through the pairing (=registration) exercise yourself!

4. Running the ULE Node using the VAR application
Time to get the ULE node up and running with the VAR simulator. This simulator converses with the
UART Driver loaded in the DHAN module at an interface called the CMND API. The VAR simulates
your MCU’s communication with the CMND - so this is means to learn about this communication
pipe as well as grasp the overall connectivity scheme of ULE.

4.4 Messages from ULE Node to Controller
The Alert On, Alert Off, Tamper, Keep Alive, On/Off/Toggle, Raw Fun messages are all items that
are sent over the link from the Node to the Controller. To send any of these messages you:
1) Select Message
2) Click Generate Button and note command generated
3) Press the Send button. This should generate an MCU < -- > CMND exchange in the VAR log
window and an incoming message in the Controller GUI log window
Alert On example is shown below:
1) The command generated by the VAR
2) The MCU < --- > CMND exchange on the Node Side. The CMND informs the MCU that it
received an ACK from the ULE Controller
3) The incoming message as seen on the graphical Log on the ULE Controller side:
4) The incoming message as seen parsed in the Log File on the ULE Controller side (This *.txt
file is located in the same directory as the DSPG Test Application.exe file):

4.5 Messages from the ULE Controller to the ULE Node
To send a message from the Controller to the Node:
1) Press the Tx Request button on upper left in HAN Window of Controller GUI. You should
observe Link Status as “Requesting”.
2) Now you need to wake up the ULE Node and have it respond to this Link Request by
triggering an event from the VAR simulator (eg Keep Alive, Tamper, Alert). You will see the
Link Status on the ULE Controller change to “In Link”. The ULE Node is now available for
an incoming message from the Controller
3) Let’s pretend that the ULE Node is an AC Outlet and send it an ON command from the
Controller GUI, HAN Window (Lower Left as shown below)
4) Now check the VAR Log window and you will notice the report of an incoming ON message:
4.6 Place the ULE Node in Hibernate and Wake it Up
The ULE Node has several options (configurable via EEPROM) for entering and exiting hibernation.
The Node in your Starter Kit has been configured to enter hibernation upon command from the MCU
(the SLEEP message in the VAR window) and exit via the Wakeup button (AMP_OUT2 from the
DHAN) on the DHX91 EVB (see the photo in the earlier section). Let’s try it!
a) Prior to entering Sleep/Hibernate you see ~28mA on your Node Power Supply
b) Generate and Send the Sleep Command
c) You should drop down to ~4µA
d) Now hit the Wakeup Button and note the return to 28mA!

this section instructions are given to reconfigure your system to operate in the DECT band allocated
by your local regulator:
Step 1: Steps 2-6 are for modifying the ULE Node Band setting. This setting will take effect upon
powering down then up the Node.
Step 2: Go the ULE Controller GUI Main Window and Open HAN Test Window
Step 3: Click the Tx Request Button in the HAN Test Window –Link Status should show “requested”
Step 4: Go the VAR Window and Send Tamper –Link Status in HAN Test Window should now
indicate “In Link” – as shown below
Step 5: Enter Value Length and Start address, Value for your Region (see table below, example given
is for transitioning to US) and hit “Set” button. Confirm change with the Get button. Now power
Down the Node
Step 6: Now for the ULE Controller Side. Close the HAN Test Window and return to the Main
Window and Click on the EEPROM Read/Write button at upper right
Step 7: You will get the EU value of 0x00. Now go to Write section and enter 0x20 for Start Adress
and Value of region –0x01 in case of the US. Hit the Write EEPROM and Confirm change with the
Read EEPROM. Power Down and Up the Controller
Step 8: Power Up the Node and send a Tamper message to the Controller. Confirm that it succeeds!!
