The nRF5 Software Development Kit for Thread helps you when developing Thread products with Nordic Semiconductor's advanced nRF52840 System on Chip (SoC).
This SDK and all of its examples are considered experimental.
The Thread examples in this pack are built on top of the OpenThread stack and the nRF5 SDK v14.1.0, which you can use to develop your applications. See nRF5 SDK v14.1.0 for full documentation of nRF5 SDK v14.1.0.
You will find the following information in this documentation:
libmbedcrypto-cc310.a) provided with this SDK. The library available in OpenThread repository does not support hardware acceleration. For more information, see ARM CryptoCell support.For more details about Thread, refer to Thread protocol specification and Thread Group.
Release Notes:
nRF5 SDK for Thread v0.11.0 --------------------------- Release Date: Week 47, 2017 This release is an experimental release and should only be used to explore and try out the Thread features available on the nRF52840 chip. The Thread examples in this pack are built on top of the OpenThread stack: https://github.com/openthread/openthread Software components and application examples for MDK, peripherals, BLE and NFC have been inherited from nRF5 SDK v14.1.0. New features: - Added Segger Embedded Studio (SES) IDE support. - Added Keil MDK-ARM IDE support. - Added new examples demonstrating: - MQTT-SN Publisher and Subscriber - Measurements of packet error rate (PER) - NFC pairing in BLE NUS (Nordic UART Service) with Thread MTD running CoAP Client - Added support for Multicast DFU. - Added USB transport for CLI and NCP examples. - Added support for Thread Sleepy End Device role in dynamic multiprotocol solution. - Added support for Thread sniffer using NCP software. Changes: - Updated SDK codebase to nRF5 SDK v14.1.0. - Updated pre-built OpenThread libraries for all supported toolchains. - Updated Thread Border Router. - Introduced Thread and CoAP utils common for all examples. - Power-optimized all Thread examples. - Modified the advertising interval of the BLE Eddystone Beacon Example to work with Timeslot API. Limitations: - Interrupts with priority 0-4 shall not be used for multiprotocol Thread/BLE examples. - Due to Thread Harness issue and non-compliant implementation of Golden Devices in the Thread Test Bed, several certification tests fail (https://threadgroup.atlassian.net/browse/TESTPLAN-380). - MQTT-SN client does not support SED role. - Multiprotocol example ble_thread_dyn_hrs_coap_srv_freertos does not work without optimization. For GCC, SES and Keil, the application running with no optimization has undefined behavior. nRF5 SDK modification: - Modified the nrf_drv_clock module to set HFCLK state correctly with the SoftDevice. - Introduced a new option FDS_VIRTUAL_PAGES_RESERVED to the FDS module to prevent overwriting of OpenThread's persistent data. - Added Block2 option support and minor fixes to the IoT CoAP library. - Modified the Secure DFU library to enable compilation without linking to BLE transport.

For certification, the following Thread Harness version has been used: - Thread V1.1 Test Harness Release 1.1.0 R45 The following OpenThread commit has been used to generate stack libraries: - https://github.com/openthread/openthread/commit/cfc84c02 - With revert of https://github.com/openthread/openthread/commit/9d66542e commit The above commit has been reverted because of a known issue in Thread Harness and Thread Test Bed: - https://threadgroup.atlassian.net/browse/TESTPLAN-380 While performing Thread Certification tests for Nordic Semiconductor's nRF52840 multiprotocol SoC, the chip was constantly connected as a Bluetooth low energy 5 peripheral device to a Bluetooth low energy central node, in addition to performing the Device Under Test (DUT) role for Thread Test Bed. The Bluetooth low energy bit rate was 1 Mbit/s, and the connection interval was 200 ms. Each node transmitted 18-19 ATT payload bytes to the peer in average 1 s interval.
