ESP-IDF Release v5.1

Documentation for IDF v5.1 is available at https://docs.espressif.com/projects/esp-idf/en/v5.1/

ESP-IDF v5.1 is a minor update for ESP-IDF v5.0. Release v5.1 is mostly compatible with apps written for ESP-IDF v5.0.

Obtaining v5.1

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 v5.1 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.1
cd esp-idf-v5.1/

This is the recommended way of obtaining v5.1 of ESP-IDF.

  • I2S STD: Enabled left_align in the default slot configuration. For the default and most used case, data_bit_width equals to slot_bit_width, which means left_align does not matter in this case
    For the case that data_bit_width is shorter than slot_bit_width, enabling left_align is a quite typical usage for almost all the codecs. (190e9e7)
  • NimBLE: Updated return type for nimble_port_init / nimble_port_deinit functions. (9916eb6)
  • IDF: All dynamic memory allocated by FreeRTOS now defaults to internal memory. To allocate FreeRTOS objects in special memory (e.g., external memory), please use one of the CreateWithCaps() functions in #include "freertos/idf_additions.h" (daf4150)

Known Issues

  • In ESP32-C6, there is a small chance of core dump when it sends advertisement and scanning
  • In ESP32-C6, DUT might crash or disconnect with AP when light sleep is enabled
  • On ESP32-C6, sometimes chip can't wakeup under low temperature, RTC memory lost under high temperature, unexpected power on reset when GPIO wakeup enabled in Deep-sleep. Can't wakeup properly under high temperature from Light-sleep
  • When using the FPU from multiple tasks on the same core there is a change that the FPU state will be corrupted, causing invalid results. Issue affects ESP32 and ESP32-S3 (#11690)

  • SDMMC/SDSPI: SD cards accept custom frequencies, not only fixed values 20 MHz or 40 MHz. See Storage migration guide for details (7d28aba)
  • ESSL: The esp_serial_slave_link is removed from the esp-idf components. Now user should use the component manager to pull it in. See example examples/peripherals/sdio/host/main/idf_component.yml for more details (03d8059)
  • Sleep: esp_light_sleep_start now returns two error num when sleep fails: ESP_ERR_SLEEP_REJECT and ESP_ERR_SLEEP_TOO_SHORT_SLEEP_DURATION (f191b2f)
  • Storage: All the partition handling APIs and data-type definitions have been moved from the 'spi_flash' to the new component 'esp_partition'. See Storage 5.x migration guide for more details (b14116f)
  • esp_chip_info() returns the chip version in the format = 100 * major eFuse version + minor eFuse version. (c546de8)
  • Wi-Fi: Modified maximum SoftAP connection number and ESPNOW encrypted connection number. (d89a512)

  • I2S STD: Enabled left_align in the default slot configuration. For the default and most used case, data_bit_width equals to slot_bit_width, which means left_align does not matter in this case.
    For the case that data_bit_width is shorter than slot_bit_width, enabling left_align is a quite typical usage for almost all the codecs. (190e9e7)
  • NimBLE: Updated return type for nimble_port_init / nimble_port_deinit functions. (9916eb6)
  • IDF: All dynamic memory allocated by FreeRTOS now defaults to internal memory. To allocate FreeRTOS objects in special memory (e.g., external memory), please use one of the CreateWithCaps() functions in #include "freertos/idf_additions.h. (daf4150)

Known Issues

  • In ESP32-H2, the low performance of Thread and BlueTooth are observed on some chips, and the fix is included in a later commit(b0e2f33).
  • In ESP32-C6, frequent start-stop wifi will make wifi unable to use.
  • In ESP32-C6, there is a small chance of core dump when it acts as SoftAP and transmits packets.
  • In ESP32-C6, there is a small chance of core dump when it sends advertisement and scanning.
  • In ESP32-C6, DUT might crash or disconnect with AP when light sleep enabled.
  • On all chips that support Bluetooth, there is a tiny chance of core dump when the BLE client accidentally disconnected from its server as the server is sending notifications.

Changelog

802.15.4

Added

  • Added support for ESP32-H2 MP chip (63d0494)
  • esp_phy: Added API esp_btbb_disable to be used by 802.15.4 and Bluetooth (e797a06)

ESP-IDF Pre-release v5.1-beta1 Pre-release
Pre-release

Documentation for IDF v5.1-beta1 is available at https://docs.espressif.com/projects/esp-idf/en/v5.1-beta1/

ESP-IDF v5.1-beta1 pre-release version is a minor update for ESP-IDF v5.0. Release v5.1 is expected to be mostly compatible with apps written for ESP-IDF v5.0.

Obtaining v5.1-beta1

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 v5.1-beta1 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.1-beta1
cd esp-idf-v5.1-beta1/

This is the recommended way of obtaining v5.1-beta1 of ESP-IDF.

ESP-IDF Release v4.3.5

Documentation for IDF v4.3.5 is available at https://docs.espressif.com/projects/esp-idf/en/v4.3.5/

ESP-IDF v4.3.5 is a bugfix update for ESP-IDF v4.3. ESP-IDF v5.0.1 is the latest stable release at the time of writing.

Obtaining v4.3.5

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:
