nRF5 SDK for Thread and Zigbee

Software Development Kit for Thread and Zigbee

A complete solution for building Thread 1.1 and Zigbee 3.0-certified products. The nRF52840 SoC and the nRF5 SDK for Thread and Zigbee together offer a powerful solution for battery powered IoT devices.

nRF5 SDK for Thread and Zigbee takes a full advantage of the multi-protocol capabilities of the nRF52840 SoC by supporting concurrent Thread/Zigbee 3.0 and Bluetooth® Low Energy operation.

Thread feature highlights:

  • Thread 1.1 certified
  • Pre-built OpenThread stack for nRF52840
  • Based on nRF5 SDK v15.2
  • Support for OpenThread Network Co-Processor (NCP)
  • Support for DFU over Thread
  • Concurrent multiprotocol between Bluetooth low energy and Thread examples
  • CoAP and MQTT-SN application layer examples
  • Border Router and cloud connectivity example
  • Thread native commissioning with NFC example
  • PC tools: Thread Topology Monitor

Zigbee feature highlights:

  • Certified as a Zigbee compliant platform
  • Pre-built Zigbee 3.0 stack provided as a library
  • Based on nRF5 SDK v15.2
  • Examples of a Zigbee device the three device types: Coordinator, Router, or End Device
  • Support for DFU over Zigbee
  • Concurrent multiprotocol of Zigbee and Bluetooth LE
