nRF5 SDK for Thread contains the pre-built OpenThread stack in the form of binary libraries. If you want to build your own project, you must include all of the mandatory libraries and can add some of the optional libraries.
The binaries can be found in the following folder: <InstallFolder>\external\openthread\lib\gcc.
The following OpenThread commit has been used to generate pre-built Thread stack libraries and for testing and verification.
Refer to OpenThread API for detailed API reference for the libraries.
Mandatory libraries:
libopenthread-ftd.a or libopenthread-mtd.a - OpenThread’s Thread Stack implementation of the Full Thread Device (FTD) or Minimal Thread Device (MTD) librarylibmbedcrypto.a – MbedTLS SSL library with CryptoCell support for operations used by OpenThread: ECC, SHA-256 and AES ECBlibopenthread-nrf52840-sdk.a - nRF52840 OpenThread’s platform implementation librarylibopenthread-platform-utils.a - OpenThread’s platform util which contains the flash manager libraryOptional libraries:
libopenthread-cli-ftd.a or libopenthread-cli-mtd.a - Command Line Interface (CLI) librarylibopenthread-ncp-ftd.a or libopenthread-ncp-mtd.a - Network Co-Processor (NCP) librarylibopenthread-diag.a – OpenThread’s diagnostic module libraryLimitations:
The pre-built OpenThread libraries located in <InstallFolder>\external\openthread\lib\gcc do not support DHCPv6 Client/Server.
Certification:
This SDK also contains the pre-built OpenThread libraries with features used by the Thread certification framework provided by Thread Group (UART logging, DHCPv6 Client/Server).
The included stack passes 148 out of 150 tests that were run with Thread V1.1 Test Harness Release 1.1.0. One test is failing due to a bug in OpenThread. A fix is submitted:
