5 Introduction
The DA14585/586 is a family of Bluetooth Smart SoC devices that operate at very low power levels
while providing world-class RF performance.
The devices are available in a small footprint while still offering a large flexibility in configuration of the
on-chip interfaces making them suitable for a wide range of applications. More information can be
found in the DA14585 Datasheet.
The development kit includes a set of hardware (for example, a development board with an on-board
debugger) and is supported by a Software Development Kit (SDK) (that is, a development toolchain,
source code examples, and so on), and documentation.
The purpose of this guide is to provide an overview of the DA14585/586 Basic Development Kit Board
and describe the setup of the hardware and installation of the software tools to fully use the board.
The following hardware and software elements are required to use the DA14585/586 Development Kit:
•The Basic Development kit
•SmartSnippets™ Studio which can be installed on Windows, see Section 8.
•Windows users should download and install terminal software such as RealTerm, Putty or Tera
Term. This document uses Tera Term for its examples.
The rest of guide is organized as follows:
•Section 6 describes the hardware components and their initial installation and setup.
•Sections 7 and 8describe the installation of the SmartSnippets™ DA14585/586 SDK software,
along with all necessary tools.
•Section 9 contains all steps for downloading and executing your first DA14585/586 Applications.
5.1 Kit Content
The Basic Development Kit parts can be ordered via various distributors. The Basic Development Kit
contains the following:

6 The DA14585/586 Hardware
The basic Development Kit consists of a single basic Board containing the DA14585/586 BLE SoC in
QFN40 package. For the schematics and layout of the board in full detail, please refer to the respective
documents on the portal.
6.1 The Basic Kit board
Figure 1 illustrates the physical layout of the Basic Kit board. The basic Kit board provides the
necessary hardware to enable:
•Full digital connectivity with external hardware using UART, SPI, GPIO, and I2C
•USB based debugging capabilities using the SEGGER J-Link on-board debugger
Figure 1: The DA14585/586 Basic Kit
6.2 Configuring the Basic Kit Board by Jumper Settings
The DA14585/586 supports booting from UART. The jumper settings are displayed below:

Figure 3 shows the layout of the header jumper, J4.
Figure 3: Jumper 4 Layout
Note: Please notice that the signals connected on the DA14585/586 SoC are located on the left
pins row of header J4 as shown in Figure 4.
Figure 4: Data direction of UART within J4
Note:
UART connectivity is enabled by shorting header as presented in Figure 2.
UART connection between DA14585/586 and the MCU that provides communication
over USB to a PC is realized through P0_4, P0_5 (for null mode), P0_6 and P0_7 (for full
UART).
For DA14585, data flash through SPI connectivity is enabled with the jumper configuration which is
presented in Figure 5.
Please notice that for DA14586, this configuration is meaningless and it must be avoided. DA14586
SoC incorporates the flash internally (2Mbits).

development kit or by coin cell battery applied on the bottom side of the development kit.
•J9: two pins header. It enables user LED. LED is driven from P1_0.
•J10: 10 pins header. It is used for monitoring DA14585/586 port 2 pins.
•J11: 10 pins header. Only P3_0 is provided on pin 1. Please notice that for DA14586, P3_0 is
not used.
Note: The schematic diagrams, BOM, and Gerber files are illustrated in detail in the
Development Kit Documentation.
6.4 Connecting the Basic Kit to the host PC
The Basic Kit includes an embedded J-Link debugger which allow easy communication with the
development host over USB.
The DA14585/586 SoC is configured only in Buck mode on this development kit. A choice can be made
between 3.3 V (via USB: J5 1-2) or VDD (a coin cell: J5 2-3). No battery is needed when running via
the mini-USB cable.
Note: The basic Kit is connected to the host PC over the connector marked as USB (J3), as
shown in Figure 6 using a standard mini-USB cable.

7 DA14585/586 Software Installation
This section describes the installation procedure for the drivers, the configuration of the serial port, and
all necessary steps to verify the connection with the PC. It also provides solutions to problems that
may occur.
7.1 Requirements of the Development PC
For proper evaluation and application development using the DA14585/586 SoC and the Basic
Development Kit, an external host is required. This external host must have a Windows already
installed and USB ports as described in Section 6.
7.2 Driver Installation
On first connection to a host PC running Microsoft Windows, the system will detect several devices
and will automatically install all necessary drivers. If the system is configured to use Windows Update,
this may take several minutes to complete.
When the driver installation is complete, the system displays a window similar to the one presented in
Figure 7.
Figure 7: Windows Driver Installation
There is one virtual COM port created by the Windows driver. This COM port (COM28 in this example)
provides a UART interface between the PC and the DA14585/586 device. For current measurement
please refer to the Figure 36 in Appendix C.
You can find also more information about the Power Profiler, see the SmartSnippets Toolbox User
Manual (UM-B-083).
Note: The COM port number assigned to the might be different to the one shown in Figure 7.
The COM port number can be found in the Windows Device Manager (Control Panel > Device Manager
> Ports (COM & LPT)) as shown in Figure 8.

7.3 Configuring the Serial Port for UART
Several development tools require UART to be routed to the FTDI serial port. Refer to Figure 32 in
Appendix B for the Basic Development Kit board connection verification and on how to properly
configure the specific port.
7.3.1 Using Serial Port
To make sure that the communication between the board and the Windows development host is
properly established, it is necessary to verify the UART connection between the two nodes.
On the Windows host, Tera Term can be used to validate the connection to the by Basic Development
Kit following these steps:
1. Connect the Basic Development Kit board to the PC via USB cable. The location of the board's
USB port is shown in Figure 6.
2. Use the Windows Device Manager to verify that the host discovered the COM28 serial port in this
case. See Figure 8.
3. Open Tera Term from the Windows Start menu as shown in Figure 9.
Figure 9: Start Tera Term
4. In the Tera Term: New connection dialog, select Serial, then select the COM Port to use, and
click OK.
5. Select Setup > Serial Port and configure your UART port using the parameters shown in Table 1
(you need to be an administrator on your local machine), see Figure 10.

7.4 Troubleshooting
If there are any problems with the connection to PC some possible solutions might be:
•Check for possible cabling issues by using a different USB cable.
•Connect the two elements using a different USB port on the host PC.
Note: If none of these actions resolve the issue, please contact Dialog Tools Forums.
8 Software Development Tools
Dialog SmartSnippets™ Studio is a royalty-free software development platform for Smartbond™
devices. It fully supports the DA14585/586 family of devices.
For the DA14585/586, KEIL must be used for compilation and debug instead of using the supplied
