    Documentation for IDF v5.4 is available at https://docs.espressif.com/projects/esp-idf/en/v5.4/

    ESP-IDF v5.4 is a minor update for ESP-IDF v5.3. Release v5.4 is mostly compatible with apps written for ESP-IDF v5.3.

    Obtaining v5.4

    For full installation instructions, see the ESP-IDF Programming Guide.

    The source files attached to this release will not work due to our use of git submodules. Use one of the following methods instead:

    Using git

    To get this release, use the following commands:

    git clone -b v5.4 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.4
cd esp-idf-v5.4/

    This is the recommended way of obtaining v5.4 of ESP-IDF.

    Major changes

    This is the list of changes since release v5.3:

    Major New Features

    • Wi-Fi: Supported ESP32-C2 chip rev2.0 Wi-Fi (e43ded7e)
    • Wi-Fi: Added FTM calibration values for ESP32-C6 (e990d1e0)
    • Wi-Fi: Supported lower coexistence power consumption when Wi-Fi disconnects from AP (5a5c0046)
    • ESP Bluedroid Host: Added support of Cover Art feature in AVRCP Controller (cda28465)
    • ESP Bluedroid Host: Added support of Device Identification Profile (ca05aa5c)
    • Bootloader: Added mocks for bootloader_support component (90cc2619)
    • Power Management: Added support for PSRAM retention in light sleep on ESP32-P4(82e76aba)
    • Peripheral Drivers: Added support for sleep retention of several peripherals in light sleep on ESP32-C6 and ESP32-H2
    • ULP: Greatly expanded support for LP Core on C6 and P4 with among others: openocd debugging support, LP-ADC, LP-SPI, ETM wakeup, LP-IO wakeup.
    • I2C: Support lp i2c instance on ESP32-P4 (ec3029eb)
    • ISP: Support a series of ISP features on ESP32-P4
    • LCD: Added i80 and RGB LCD driver support on ESP32-P4 (fdd90d48) (6d716388)
    • Touch Sensor: New touch sensor on ESP32-P4 (c23165bb)
    • MbedTLS: Support ESP32-C2 rev2.0 ROM mbedtls-v3.6.0 (9a47de53)
    • Supported ESP32-C2 chip rev2.0 (b70331a9)
    • PSRAM: Supported APS3204L (cb9f4740)
    • Thread: Supported Thread Radio Encapsulation Link (TREL) feature (d1ef4230)

    Breaking Changes

    • Core System: Renamed __VA_NARG__ and its macros to be prefixed with ESP_, i.e. __VA_NARG__ to ESP_VA_NARG to avoid naming collisions. If using these then update to use the new name. (bb8fa930)
    • Security / ESP Cert Bundle: Due to changes in the certificate bundle format to reduce RAM usage, the use of pre-generated certificate bundles using the older format would now be incompatible with the newer application binaries. You now need to either use the default ESP-IDF build system method for attaching the certificate bundle while building applications or update your pre-generated certificate bundle binaries by generating them using the latest gen_crt_bundle.py script. (fa4c3873)
    • SDMMC: Function sdmmc_host_init no longer returns ESP_ERR_INVALID_STATE when the SDMMC host is already initialized, now it returns ESP_OK. (d1571c14)
    • SPI Flash: Removed XMC-C suspend support because there is risk that erase operation might never finish (121a272e)
    • Wi-Fi: Removed the definition of the "WIFI_BAND_2G_5G" field in "wifi_band_t". (7b5014a0)
    • ESP Bluedroid Host: Added new Kconfig option to enable SDP APIs and remove the dependency of SDP on L2CAP Kconfig option
    • LWIP / PPP: PPPoS internal callback function has incompatible prototype. Please use esp_netif API or update your function callbacks. (d4f60feb)
    • Modify the type of "bandwidth" and comment in wifi_ap_record_t. (3b0cf1a2)
    • ESP HTTP Server: HTTP version 1.0 was previously supported due to a software bug. With this update, only HTTP/1.1 is allowed. (57553ecf)
    • MbedTLS: MbedTLS option MBEDTLS_ECP_FIXED_POINT_OPTIM is disabled by default to save on significant (~27KB) flash footprint. This allows easier migration from IDF 4.x to 5.x release. If the performance is desired and ECC accelerator is not available then the config can be turned on. (27f11f87)
    • MbedTLS: Supported for SHA3 operations is now configurable and disabled by default to save flash size. The config can be enabled if an application needs to perform SHA3 operations. (27f11f87)
    • Bluetooth Common / Controller: Move esp_wifi_bt_power_domain_on and esp_wifi_bt_power_domain_off from esp_bt.h to esp_phy_init.h (a09d5747)
    • For ESP32-C6, to continue to use RC32K clock as the RTC slow clock source now requires to select RTC_CLK_SRC_USE_DANGEROUS_RC32K_ALLOWED Kconfig first; For ESP32-H2/ESP32-P4, this option is completely removed. (0f1bec18)

    Known Issues

    • For ESP32-P4 chips, when ESP_SLEEP_KEEP_DCDC_ALWAYS_ON is not enabled (enabled by default), accessing external storage (Flash/ PSRAM) after waking up from light sleep may get incorrect data.
