MDEK1001 stands for Module Development & Evaluation Kit for the Decawave DWM1001. 1.2 The DWM1000 module and RTLS The DWM1001 is a module product that comes complete with firmware to allow system developers to quickly implement an RTLS to suit their particular end application, or add RTLS capability to an existing system. The module may be configured to behave as an “anchor” one of the fixed nodes in the system or a “tag” one of the mobile located nodes in the system. The module configuration may be achieved either via Bluetooth using the companion application (Decawave DRTLS Manager) or via an SPI or UART connection from an external host. The module incorporates Decawave’s DW1000 UWB transceiver which the module’s onboard firmware drives to implement the network of anchor nodes and perform the two-way ranging exchanges with the tag nodes enabling each tag to compute its own location. The module also incorporates the Nordic Semiconductor NRF52832 IC providing the Bluetooth connectivity used for configuration and the microprocessor that runs the firmware which drives the DW1000 and provides the RTLS enabling functionality. A more complete description of this may be found in DWM1001 System Overview. The module is typically mounted on a PCB, such as the DWM1001-DEV product. The MDEK1001 kit provides 12 DWM1001 modules already mounted on “development” boards enabling system developers evaluate the product and/or begin their system development before embarking on their own designs. 1.3 Main Features of the MDEK1001 1.4 Out-of-the-box wireless Real-Time Location System (RTLS), including anchors and tags (and gateway support) without designing any hardware or writing a single line of code Quick and easy installation and setup 12 RTLS units (DWM1001-DEV) configurable as 4 to 11 anchors and 1 to 8 tags Configure and control the module via APIs via UART/SPI/Bluetooth Modify the module firmware to customise your application Configuration & location application for tablets/smartphones (Android 6.0 or 7.0) Configuration & location web client (Q1 2018) Analytics Note: the Android application (Decawave DRTLS Manager) reports application crash diagnostics back to Decawave (and design partner) in order to improve future versions. 1.5 More Information More information about the MDEK1001, the DWM1001-DEV Development Board, the DWM1001 module and the DW1000 IC can be found on the Decawave website. © Decawave 2017 OP-MDEK1001-System-User-Manual-1.0 Page 8 MDEK1001 Kit User Manual 2 KIT CONTENTS 2.1 Supplied in the MDEK1001 Box The following items are included in the box.

Note that this feature may result in a small error in anchor location, making reported tag locations less accurate. For best results it is recommended that anchor positions are measured to cm accuracy and manually entered (see below) Note 2: Ensure Line-of-Sight between the anchors during these steps Figure 18: Auto-Positioning Screen START On the ‘Network Details’ screen, tap the “Auto-Position” button in the upper right pull-down menu (anchors within Bluetooth range appear) RE-ORDER Re-order the anchors in the list to match their locations in the room: o Order the anchors anti-clockwise in the room (as shown above) o The 1st anchor in the list is the (0,0) co-ordinate MEASURE Tap “Measure” to start the auto-positioning PREVIEW Tap ‘PREVIEW’ to check locations before saving SET HEIGHTS Enter heights of the anchors by tapping ‘Z-AXIS’ SAVE Save the anchors setup by tapping ‘SAVE’ The location of the other anchors are calculated from the initial 3 anchor locations Errors will propagate through the anchors so the usage is confined to small-scale systems e.g. up to 4 anchors Auto-positioning can only be used on the anchors that are within Bluetooth range of the android device. © Decawave 2017 OP-MDEK1001-System-User-Manual-1.0 Page 27 MDEK1001 Kit User Manual Figure 19: Auto-Positioning: Anchor Positioning Rules 7.4.5.2 By Manual Positioning 7.5 In turn, open each anchor’s device configuration screen Enter the x, y, z co-ordinates of the anchors Show Location Ranging starts automatically once devices have been added to the network and the display option has been tapped (it defaults to off) From the Network Details screen, tap the “Grid” option at the top of the screen to see the grid Pinch to zoom in or out Tags automatically select the optimum 4 anchors for ranging A floorplan can be uploaded into the application from the device’s gallery © Decawave 2017 OP-MDEK1001-System-User-Manual-1.0 Page 28 MDEK1001 Kit User Manual Figure 20: Grid Screen – Anchor Placement & Tag Tracking In networks where there are more than 4 anchors, the anchor selection can be viewed on the grid by moving the tag from one position to another.

Note also that the PC terminal can be used to configure the anchors and tags – the Android application is not necessarily needed. 8.1 Instructions 1. Setup the anchors and tags network via the Android application (see section 7) 2. Download and install the J-Link software pack from Segger https://www.segger.com/downloads/jlink/#JLinkSoftwareAndDocumentationPack 3. Download and install a common PC terminal program e.g. Tera Term http://download.cnet.com/Tera-Term/3000-2094_4-75766675.html 4. Connect the tag to the PC via USB cable 5. Open the device manager to identify what com port is assigned to the Tag, in this case COM20 6. Once the com port has been identified open up Tera Term. Select the appropriate COM port as shown, and set the terminal baud rate to 115200. The tag should now be connected. © Decawave 2017 OP-MDEK1001-System-User-Manual-1.0 Page 34 MDEK1001 Kit User Manual 7. Next press the PC Enter key two times and the prompt below appears: 8. Enter the command ‘nmt’ and press the return key twice which sets the tag into Active mode 9. Enter ‘les’ to display the location estimates of the tag 8.2 Example Output In the example above, ‘08AF’ is an Anchor ID: ‘[0.5,0.5,1.97]’ is the Anchor coordinate for Anchor ‘08AF’ in the form of [x,y,z]. ‘1.14’ is the estimated range between the Tag and Anchor ‘08AF’ ‘est[1.05,1.04,1.15,92] ‘ is the estimated location of the Tag. In the form of [x,y,z,quality factor]. (The quality factor is a measure of confidence of the accuracy of the location estimate based on the ranges received) 8.3 Other Commands Once tag is connected to tera term press ‘ ?’ and then the return key to obtain a list of the executable commands.
