Enabling this option will greertos the Task Watchdog Timer to be initialized automatically at startup. So the recommendation is to disable this option. Once secure boot is enabled, bootloader will only boot if partition table maual app image are signed. The recommended value is: This pool will be used to allocate memory for thrown exceptions when there is not enough memory on the heap. The same macro should be entered if certain pin will not be used.

PHY calibration will be skipped on deep sleep wakeup. If enable flow ctrl, the num must be above 9.

UDP receive mail box is a per socket mail box, when the application receives packets xonfiguration UDP socket, LWIP core firstly posts the packets to UDP receive mail box and the application then fetches the packets from mail box. Select this option to enable Bluetooth and freertis the submenu with Bluetooth configuration choices. Freertos reference manual – api functions and configuration options to accept value of UART baud rate.

Note that run time stats are only valid until the clock source overflows. Generally bigger value means higher throughput but more memory.

The valid value is from 1 to The maximum number of DHCP clients that are connected to the server. Recommended for freertos reference manual – api functions and configuration options traffic scenarios.

Maximum MQTT receive buffer size. On the other hand, if the receiv mail box is too small, the mail box may be recerence. This file is never touched by the build anx, and must be created manually. Size of the buffer for events in bytes. Maximum MQTT transmit buffer size. Bit mask of the interrupt status to be cleared. In these cases, we may run out of TX buffers. The build system offers a way to avoid this, in the form of sdkconfig.

If PHY init data is stored in a partition, it has to be flashed there, otherwise runtime error will occur.

Other attenuations do not exhibit non-linear behavior hence will not be affected by this option. The interrupt handlers have their own stack. If more than one SHA digest is calculated at the same time, one will be calculated fully in hardware and the rest will be calculated at least partially calculated in software.

As result several resources required by the UART will be allocated. Freertos reference manual – api functions and configuration options buffer takes approximately 1. Timeout period configuration for the Task Watchdog Timer in seconds.

It is possible to suppress these debug outputs by enabling this option. SHA hardware acceleration is faster than software in some situations but slower in others.

If this option is not enabled, PHY init data will be embedded into the application binary. The stack size may need to be increased above the default if the app installs idle or thread local storage cleanup hooks that use a lot of stack memory. The CPU Clock can run at a higher frequency hence provide a finer resolution but will overflow much quicker. If you need bit integer formatting support or C99 features, keep this option disabled.


Setting a smaller default receive window size can save some RAM, but will significantly decrease performance.

freertos reference manual – api functions and configuration options Enable this to have an identifiable spiffs filesystem. Disable this for slightly faster startop. Longer messages are dropped. When using a custom universal MAC address range, the correct setting will depend on the allocation of MAC addresses in this range either 2 or 4 per device. The layer3 buffer is allocated from the heap, so the total layer3 receiving buffer depends on the available heap size, when heap runs optiions of memory, no copy will be sent to layer3 and packet will be dropped in layer2.

The format is the same as that of the sdkconfig file. For some applications especially UDP applications, the upper layer can deliver fteertos faster than WiFi layer can transmit.

See mbedTLS documentation for more details.

This helps prevent flash chip from browning out during flash programming operations. Three options are possible: If this setting is disabled, the app can only be booted by bootloaders from IDF v2.

If failed, try to allocate internal memory then. Found in Compiler options. By convention, all option names are upper case with underscores.
