Documentation for release v3.1.4 is available at https://docs.espressif.com/projects/esp-idf/en/v3.1.4/

ESP-IDF v3.1.4 is a bugfix-only update for ESP-IDF v3.1.3. Release v3.1.4 is compatible with apps written for ESP-IDF v3.1.x.

This is the list of changes since release v3.1.3:

Known Issues

  • Calling esp_wifi_stop() can lead to a memory leak under some rare circumstances

Major Bug Fixes

  • cmake build system: Apply PSRAM compiler workaround correctly
  • gpio driver: Fixed issue with holding GPIO levels in deep sleep
  • Added configuration option for Wi-Fi IRAM optimization, allows reducing IRAM usage
  • Decouple mesh from Wi-Fi libraries, reducing binary size if Wi-Fi is used without Mesh
  • Fixed Wi-Fi STA failing to connect to some APs (Xiaomi hotspots, some others) after reset
  • Updated some Wi-Fi configuration option ranges and defaults for better performance, especially when using PSRAM
  • Fixed iPhone failing to connect to ESP32 AP (enabling AP BAR receive)
  • Fixed BLE adv reports not returned when sleep is enabled
  • Added flow control support for BLE adv reports
  • Fixed two BLE connection params update issues:
  • Fixed iOS and Windows 10 compatibility error with BLE HID

Wi-Fi Related

  • Updated some Wi-Fi configuration option ranges and defaults for better performance, especially when using PSRAM
  • New configuration option for Wi-Fi IRAM optimization, allows reducing IRAM usage.
  • Decouple mesh from Wi-Fi libraries, reducing binary size if Wi-Fi is used without Mesh
  • Added option to configure number of Wi-Fi management short buffers
  • Fixed several Wi-Fi scan bugs
  • Fixed a crash caused by Wi-Fi static TX buffer alloc/free
  • Fixed iPhone failing to connect to ESP32 AP (enabling AP BAR receive)
  • Fixed ESP32 STA failing to connect to some APs (Xiaomi hotspots, some others) after reset
  • Fixed bug that STA incorrectly deletes BA when receiving DelBA request
  • Added additional out of memory checks in Wi-Fi library
  • Fixed the bug that STA incorrectly receives packets when scanning in connected status
  • Increased the block scan internal timeout value

Bluetooth Related

  • Fixed crash when inquiry stops
  • Added vendor HCI command functionality
  • Fixed assert(8192 0) in rwble.c 234
  • Fixed some warnings when Bluedroid logging was disabled

Coexistence

  • Fixed LC protection cause memory corrupted (Strange crash like IllegalInstruction, LoadProhibited and ...)
  • Fixed Bluetooth disconnecting due to too many reset BB
  • Fixed bug where no TBTT would be generated after receiving wrong Wi-Fi beacon (when coexistence is enabled)

BLE Related

  • Fixed iOS and Windows 10 compatibility error with BLE HID
  • Fixed uncommon crash when BE performs re-connect/re-scan/re-adv
  • Fixed two connection params update issues:
    • Connection parameters update cause link loss while data is being sent
    • BLE disconnect while connection parameters is reject by LL_REJECT_IND
  • Fixed not checking scan window and interval when setting scan parameters
  • Fixed BLE not sending or receiving packets under some conditions
  • Fixed esp_ble_gatts_get_attr_value() API error
  • Added flow control support for BLE adv reports
  • Fixed adv reports not returned when sleep is enabled

Blufi

  • Fixed a bug when preparing to write

LWIP related

  • Fixed LWIP autoip memory leak

Ethernet related

  • Increase Ethernet task stack size and make configurable

mDNS related

  • Fixed memory leak when query for services receives multiple PTR entries for one instance
  • Fixed possible crash when mdns_free called while action queue not empty
  • Fixed invalid query_txt
  • Fixed memory leak in pbuf if tcpip_adapter failed to get network interface
  • Fixed possible crash when packet queued for transmit referenced a deleted service
  • Fixed a race condition when updating packet data from a user task if allocation/queueing failed
  • Fixed a possible deadlock in mdns deinit when calling mdns_free()
  • Fixed concurrent access to mdns PCBs when starting the service thread
  • Fixed a possible crash when probing a particular interface whose network has naming conflicts
  • Fixed task synchronization to use a semaphore not a mutex

Bootloader related

  • Fixed issues when bootloader was compiled for a different CPU frequency than the app (#2731)

System Related

  • freertos: Made xPortGetCoreID() function volatile, fixing an issue where core ID may not be correctly updated when called twice in an un-pinned function. (#3093)
  • heap: Added checks for integer overflows
  • psram: Fixed issue where some files (*lock.c, *creat.c) were incorrectly linked to IRAM when PSRAM was enabled

Peripheral Driver Related

  • gpio: Added new APIs for holding GPIO levels in deep sleep
  • rmt: Added missing get function to RMT API: rmt_get_idle_level() (#2666)
  • rmt: Suppressed error message from rmt_wait_tx_done() if wait_time==0 (allows for polling) (#2666)
  • spi: Fixed bug connecting SPI peripheral to read-only pins (#2455)

Protocol Related

  • esp_tls config structure cacert_pem_bytes is now a mutable integer

Storage Related

  • nvs: Fixed out of memory issues due to lazy NVS HashListBlock cleanup (#1642)

Tooling Related

  • idf_size: Fixed sorting of libraries in idf_size.py output
  • kconfig: Fixed compatibility with very old versions of "flex"
  • build system: Fixed some situations where EXTRA_COMPONENT_DIRS finds components in the wrong directories.
  • cmake build system: Apply PSRAM compiler workaround correctly
  • cmake build system: Disable stack protector in startup code (#2990)
  • cmake: Fix some cases where python scripts were executed directly, not via PYTHON variable (
  • nvs_util: Fixed support for writing multiple single pages of big blob data (#3011)
  • nvs_util: Disable multipage blob support by default (requires configuration option to be supported in IDF v3.1 projects)

Obtaining v3.1.4

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 v3.1.4 --recursive https://github.com/espressif/esp-idf.git esp-idf-v3.1.4
cd esp-idf-v3.1.4/

This is the recommended way of obtaining v3.1.4 of ESP-IDF.
