Common switches
OpenThread allows you to configure the stack for different functionality and behavior. This configuration is based on changing compile-time constants during the build process using common switches listed in /examples/common-switches.mk.
This page lists the available common switches with description. Unless stated otherwise, the switches are set to 0 by default. For build command examples, see build examples.
| Makefile switch | CMake switch | Description |
|---|---|---|
| ANYCAST_LOCATOR | OT_ANYCAST_LOCATOR | Enables anycast locator functionality. |
| BACKBONE_ROUTER | OT_BACKBONE_ROUTER | Enables Backbone Router functionality for Thread 1.2. |
| BIG_ENDIAN | OT_BIG_ENDIAN | Allows the host platform to use big-endian byte order. |
| BORDER_AGENT | OT_BORDER_AGENT | Enables support for border agent. In most cases, enable this switch if you are building On-mesh Commissioner or Border Router with External Commissioning support. |
| BORDER_ROUTER | OT_BORDER_ROUTER | Enables support for Border Router. This switch is usually combined with the BORDER_AGENT and UDP_FORWARD (or PLATFORM_UDP in case of RCP design) switches to build Border Router device. |
| BORDER_ROUTING | OT_BORDER_ROUTING | Enables bi-directional border routing between Thread and Infrastructure networks for Border Router. |
| BORDER_ROUTING_NAT64 | OT_BORDER_ROUTING_NAT64 | Enables NAT64 border routing support for Border Router. |
| BUILTIN_MBEDTLS_MANAGEMENT | OT_BUILTIN_MBEDTLS_MANAGEMENT | Enables the built-in mbedTLS management. Enable this switch if the external mbedTLS is used, but mbedTLS memory allocation and debug config should be managed internally by OpenThread. |
| CHANNEL_MANAGER | OT_CHANNEL_MANAGER | Enables support for channel manager. Enable this switch on devices that are supposed to request a Thread network channel change. This switch should be used only with an FTD build. |
| CHANNEL_MONITOR | OT_CHANNEL_MONITOR | Enables support for channel monitor. Enable this switch on devices that are supposed to determine the cleaner channels. |
| CHILD_SUPERVISION | OT_CHILD_SUPERVISION | Enables support for child supervision. Enable this switch on a parent or child node with custom OpenThread application that manages the supervision, checks timeout intervals, and verifies connectivity between parent and child. |
| COAP | OT_COAP | Enables support for the CoAP API. Enable this switch if you want to control Constrained Application Protocol communication. |
| COAP_OBSERVE | OT_COAP_OBSERVE | Enables support for CoAP Observe (RFC7641) API. |
| COAPS | OT_COAPS | Enables support for the secure CoAP API. Enable this switch if you want to control Constrained Application Protocol Secure (CoAP over DTLS) communication. |
| COMMISSIONER | OT_COMMISSIONER | Enables support for Commissioner. Enable this switch on device that is able to perform Commissioner role. |
| COVERAGE | OT_COVERAGE | Enables the generation of code-coverage instances. |
| CSL_RECEIVER | OT_CSL_RECEIVER | Enables CSL receiver feature for Thread 1.2. |
| DEBUG | not implemented | Allows building debug instance. Code optimization is disabled. |
| DHCP6_CLIENT | OT_DHCP6_CLIENT | Enables support for the DHCP6 client. The device is able to act as typical DHCP client. Enable this switch on a device that is supposed to request networking parameters from the DHCP server. |
| DHCP6_SERVER | OT_DHCP6_SERVER | Enables support for the DHCP6 server. The device is able to act as typical DHCP server. Enable this switch on a device that is supposed to provide networking parameters to devices with DHCP_CLIENT switch enabled. |
| DIAGNOSTIC | OT_DIAGNOSTIC | Enables diagnostic support. Enable this switch on a device that is tested in the factory production stage. |
| DISABLE_BUILTIN_MBEDTLS | not implemented | Disables OpenThread's mbedTLS build. Enable this switch if you do not want to use the built-in mbedTLS and you do not want to manage mbedTLS internally. Enabling this switch will disable support for such features as memory allocation and debug. |
| DISABLE_DOC | not implemented | Disables building of the documentation. |
| DISABLE_EXECUTABLE | not implemented | Disables building of executables. |
| DISABLE_TOOLS | not implemented | Disables building of tools. |
| DEBUG_UART | not implemented | Enables the Debug UART platform feature. |
| DEBUG_UART_LOG | not implemented | Enables the log output for the debug UART. Requires OPENTHREAD_CONFIG_ENABLE_DEBUG_UART to be enabled. |
| DNS_CLIENT | OT_DNS_CLIENT | Enables support for DNS client. Enable this switch on a device that sends a DNS query for AAAA (IPv6) record. |
| DNS_DSO | OT_DNS_DSO | Enables support for DNS Stateful Operations (DSO). |
| DNSSD_SERVER | OT_DNSSD_SERVER | Enables support for DNS-SD server. DNS-SD server use service information from local SRP server to resolve DNS-SD query questions. |
| DUA | OT_DUA | Enables the Domain Unicast Address feature for Thread 1.2. |
| DYNAMIC_LOG_LEVEL | not implemented | Enables the dynamic log level feature. Enable this switch if OpenThread log level is required to be set at runtime. See Logging guide to learn more. |
| ECDSA | OT_ECDSA | Enables support for Elliptic Curve Digital Signature Algorithm. Enable this switch if ECDSA digital signature is used by application. |
| EXCLUDE_TCPLP_LIB | OT_EXCLUDE_TCPLP_LIB | Exclude TCPlp library from the build. |
| EXTERNAL_HEAP | OT_EXTERNAL_HEAP | Enables support for external heap. Enable this switch if the platform uses its own heap. Make sure to specify the external heap Calloc and Free functions to be used by the OpenThread stack. |
| FULL_LOGS | OT_FULL_LOGS | Enables all log levels and regions. This switch sets the log level to OT_LOG_LEVEL_DEBG and turns on all region flags. See Logging guide to learn more. |
| HISTORY_TRACKER | OT_HISTORY_TRACKER | Enables support for History Tracker. |
| IP6_FRAGM | OT_IP6_FRAGM | Enables support for IPv6 fragmentation. |
| JAM_DETECTION | OT_JAM_DETECTION | Enables support for Jam Detection. Enable this switch if a device requires the ability to detect signal jamming on a specific channel. |
