Miscellaneous Constants

Define as 1 to enable support for an empty network name (zero-length: "")

Define as 1 to enable assert check of pointer-type API input parameters against null.

Enabling this feature can increase code-size significantly due to many assert checks added for all API pointer parameters. It is recommended to enable and use this feature during debugging only.

Define as 1 to enable assert function OT_ASSERT() within OpenThread code and its libraries.

Define to 1 to enable TCAT over BLE support.

The default IEEE 802.15.4 channel.

Specifies the value used in emitted Connectivity TLV "Rx-off Child Buffer Size" field which indicates the guaranteed buffer capacity for all IPv6 datagrams destined to a given rx-off-when-idle child.

Changing this config does not automatically adjust message buffers. Vendors should ensure their device can support the specified value based on the message buffer model used:

• OT internal message pool (refer to OPENTHREAD_CONFIG_NUM_MESSAGE_BUFFERS and MESSAGE_BUFFER_SIZE), or
• Heap allocated message buffers (refer to OPENTHREAD_CONFIG_MESSAGE_USE_HEAP_ENABLE),
• Platform-specific message management (refer toOPENTHREAD_CONFIG_PLATFORM_MESSAGE_MANAGEMENT`).

Specifies the value used in emitted Connectivity TLV "Rx-off Child Datagram Count" field which indicates the guaranteed queue capacity in number of IPv6 datagrams destined to a given rx-off-when-idle child.

Similar to OPENTHREAD_CONFIG_DEFAULT_SED_BUFFER_SIZE, vendors should ensure their device can support the specified value based on the message buffer model used.

The default IEEE 802.15.4 transmit power (dBm).

The default IEEE 802.15.4 wake-up channel.

Define to 1 to generate ECDSA signatures deterministically according to RFC 6979 instead of randomly.

Specifies the default device power supply config.

This config MUST use values from otPowerSupply enumeration.

Device manufacturer can use this config to set the power supply config used by the device. This is then used as part of default otDeviceProperties to determine the Leader Weight used by the device.

The size of dtls application data when the CoAP Secure API is enabled.

Define as 1 to support Thread 1.2 Domain Unicast Address feature.

Define to 1 to enable ECDSA support.

Define as 1 to enable builtin-mbedtls.

Note that the OPENTHREAD_CONFIG_ENABLE_BUILTIN_MBEDTLS determines whether to use builtin-mbedtls as well as whether to manage mbedTLS internally, such as memory allocation and debug.

Define as 1 to enable builtin mbedtls management.

OPENTHREAD_CONFIG_ENABLE_BUILTIN_MBEDTLS_MANAGEMENT determines whether to manage mbedTLS memory allocation and debug config internally. If not configured, the default is to enable builtin management if builtin mbedtls is enabled and disable it otherwise.

Enable the "Debug Uart" platform feature.

In the embedded world, the CLI application uses a UART as a console and the NCP application can be configured to use either a UART or a SPI type device to transfer data to the host.

The Debug UART is or requires a second uart on the platform.

The Debug Uart has two uses:

Use #1 - for random 'debug printf' type messages a developer may need Use #2 (selected via DEBUG_LOG_OUTPUT) is a log output.

See #include for more details

This setting configures the number of consecutive MCPS.DATA-Confirms having Status NO_ACK that cause a Child-to-Parent link to be considered broken.

Enable the external heap.

The size of heap buffer when DTLS is enabled.

The size of heap buffer when DTLS is disabled.

Define to 1 to enable the Jam Detection service.

The default Joiner UDP port.

The maximum number of state-changed callback handlers (set using otSetStateChangedCallback()).

The size of a message buffer in bytes.

Message buffers store pointers which have different sizes on different system. Setting message buffer size according to the CPU word length so that message buffer size will be doubled on 64bit system compared to that on 32bit system. As a result, the first message always have some bytes left for small packets.

Some configuration options can increase the buffer size requirements, including OPENTHREAD_CONFIG_MLE_MAX_CHILDREN and OPENTHREAD_CONFIG_COAP_BLOCKWISE_TRANSFER_ENABLE.

Whether use heap allocator for message buffers.

Define as 1 to support Thread 1.2 Multicast Listener Registration feature.

Define to 1 to enable multipan RCP support.

Define to 1 to enable multiple instance support.

Define number of OpenThread instance for static allocation buffer.

Define to 1 to enable multiple static instance support.

Define as 1 to enable support for Neighbor Discover Agent.

The number of message buffers in the buffer pool.

Define as 1 to enable support for locally initializing an Active Operational Dataset.

Define to 1 to enable OTNS interactions.

Define to 1 to enable otPlatFlash* APIs to support non-volatile storage.

When defined to 1, the platform MUST implement the otPlatFlash* APIs instead of the otPlatSettings* APIs.

Define to 1 to enable crash dump logging.

On platforms that support crash dump logging, this feature will log a crash dump using the OT Debug Log service.

Logging a crash dump requires the platform to implement the otPlatLogCrashDump() function.

Define to 1 to support proprietary radio configurations defined by platform.

The settings storage path on posix platform.

Define to 1 to support OQPSK modulation in 2.4GHz frequency band.

The physical layer parameters are defined in section 6 of IEEE802.15.4-2006.

Define to 1 to support OQPSK modulation in 915MHz frequency band.

The physical layer parameters are defined in section 6 of IEEE802.15.4-2006.

Define to 1 to enable Thread Test Harness reference device support.

The Organizationally Unique Identifier for the Thread stack.

The Stack Version Major for the Thread stack.

The Stack Version Minor for the Thread stack.

The Stack Version Revision for the Thread stack.

The value ahead of the current frame counter for persistent storage.

Define to 1 to enable UDP forward support.

Define to 1 to enable tracking the uptime of OpenThread instance.

Define to 1 to enable Verhoeff checksum utility module.
