UG350: Silicon Labs Coexistence Development Kit (SLWSTK-COEXBP) The Coexistence Development Kit (SLWSTK-COEXBP) is a de- KEY POINTS velopment kit designed by Silicon Labs to demonstrate coexis- tence between different radios transmitting in the 2.4 GHz ISM Describes coexistence hardware and band. This document version pertains to revision 3.0 of the related software requirements. Provides step-by-step instructions for the SLWSTK-COEXBP kit. SLWSTK-COEXBP also requires the installation and configuration of EFR32MG Wireless Starter Kit (SLWSTK6000B), which contains coexistence features in software. the following devices: Details hardware included in the kit and how to use it. 3 x Wireless starter kit (WSTK) mainboard (BRD4001A) Explains additional software plugins and 3 x EFR32MG12 2.4 GHz 19 dBm radio board (BRD4161A) packages used for advanced testing. 3 x EFR32MG12 2.4 GHz 10 dBm radio board (BRD4162A) A Logic Analyzer, to view the logic signals, is optional but recommended. A Silicon Labs protocol stack is required to enable and run coexistence features. Any of the following stack versions can be used:: Silicon Labs EmberZNet PRO (Zigbee) stack (v. 6.9.0 and up) Silicon Labs Bluetooth SDK (v. 3.1.0 and up) Silicon Labs OpenThread (OpenThread) SDK (v. 1.1.0.0 and up) Software required to run and view logic analyzer waveforms The software images required to create a Zigbee, Bluetooth, or OpenThread network with coexistence features enabled must be built through sample applications in the re- spective stack, with added modifications discussed in this document. The PTA Controller software required to emulate the Wi-Fi device behavior and exer- cise the coexistence features is available as a custom application. Instructions on how to download the application from GitHub are provided. The following additional documents from Silicon Labs are useful resources for under- standing protocol networks and coexistence, and will also be referred to in this user s guide: QSG106: Zigbee EmberZNet PRO Quick-Start Guide QSG169: Bluetooth SDK v3.x Quick-Start Guide QSG170: Silicon Labs OpenThread Quick-Start Guide AN1017: Zigbee and Thread Coexistence with Wi-Fi AN1128: Bluetooth Coexistence with Wi-Fi UG103.17 Wi-Fi Coexistence Fundamentals silabs.com Building a more connected world. Rev. 0.5 UG350: Silicon Labs Coexistence Development Kit (SLWSTK-COEXBP) Introduction 1. Introduction SLWSTK-COEXBP: Silicon Labs Coexistence Development Kit is designed to demonstrate multiple radio coexistence features availa- ble as part of the SDK. These features enable radios in a single product (that is, Gateway, Hub, and so on) running on different proto- cols to arbitrate network traffic to avoid interference. A Coexistence test configuration requires the following components: Three WSTK boards with either 19 or 10 dBm radio boards mounted, and loaded with the following software images: PTA (Packet Traffic Arbitration) Controller: Acts as a Wi-Fi emulator and responds to activity on the device running the coexis- tence features (coexistence device). Coexistence device application: Sample protocol application with coexistence features enabled. End-node device application: Sample protocol application to help create a network and generate wireless traffic. Coexistence Backplane Board A logic analyzer is optional but highly recommended to enable signal analysis and debugging. In our setup, we use a Saleae logic ana- lyzer. To set up the recommended coexistence test configuration, the PTA Controller and coexistence device both are plugged into headers on the Coexistence Backplane Board. The Coexistence Backplane Board has routes between those headers that enable connections between the two boards. The Coexistence Backplane Board also has routes from the headers to external test points. This allows prob- ing the signals for debugging and evaluation purposes. The end-node device is not plugged into the Coexistence Backplane Board. The recommended configuration for using the Silicon Labs Coexistence Development Kit is shown in the following figure. Figure 1.1. Typical Coexistence Test Configuration Using a Zigbee Example This configuration is shown in the following figures. silabs.com Building a more connected world. Rev. 0.5 2
