Documentation for IDF v5.1.7 is available at https://docs.espressif.com/projects/esp-idf/en/v5.1.7/

ESP-IDF v5.1.7 is a bugfix update for ESP-IDF v5.1 and also the last bug fix release of ESP-IDF v5.1. According to ESP-IDF Support Period Policy, ESP-IDF v5.1 release branch reached end-of-life in December 2025. With EOL, new features, bug fixes, and security fixes will no longer be supported on this branch. Customers who are currently using ESP-IDF v5.1 release branch are encouraged to upgrade their projects to more recent ESP-IDF releases, such as ESP-IDF v5.5.x.

Obtaining v5.1.7

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 v5.1.7 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.1.7
cd esp-idf-v5.1.7/

This is the recommended way of obtaining v5.1.7 of ESP-IDF.

Download an archive with submodules included

Attached to this release is an esp-idf-v5.1.7.zip archive. It includes .git directory and all the submodules, so can be used out of the box. This archive is provided for users who have connectivity issues preventing them from cloning from GitHub. To reduce the size of the archive, the .git directory doesn't include the history of commits older than one year. Users who need to use git checkout to access an older release of IDF will have to use git fetch first to download the remaining part of the history.

Major changes

Breaking Changes

• 15.4/MAC: Added a duration argument for ieee802154_receive_at() (c70a55c)
  Application Utilities/Provisioning Security2 scheme has been updated for AES-GCM IV usage. Please refer to security2 scheme documentation for changes required on the provisioning entity side. (84467ec)
• BLE/Controller: Fixed occasional assertion in adv/scan/connection coexistence scenario on ESP32-H2. (22ced0a)
• BLE/Controller: Fixed occasional assertion in scan/connection coexistence scenario on ESP32-C6. (22ced0a)
• Bluetooth Common: Starting from this version, Espressif's Bluetooth vendor-specific HCI commands and events for all ESP Bluetooth chips are disabled by default in HCI UART mode and non-ESP host mode. Please refer to esp_bt_vs.h (E.g., components/bt/include/esp32/include/esp_bt_vs.h) for detailed information . (1f4106f)
• Security: The ECDSA peripheral of the ESP32-H2 supports both ECDSA-P192 and ECDSA-P256 operations. However, starting with ESP32-H2 revision 1.2, only ECDSA-P256 operations are enabled by default. CONFIG_ESP_ECDSA_ENABLE_P192_CURVE need to be enable to turn on the ECDSA-P192 operations. (6383285)
• Security/MbedTLS: If using MbedTLS for server certificate verification, it is mandatory to call mbedtls_ssl_set_hostname before the connection begins. No change is required if the application uses esp-tls layer. (b8f6564)
• WI-FI: esp_wifi_set_config would returned ESP_ERR_WIFI_STATE when wifi was in connecting state. (238266d)
