Documentation for release v3.3-beta3 is available at https://docs.espressif.com/projects/esp-idf/en/v3.3-beta3/

v3.3-beta3 is a prerelease of ESP-IDF v3.3. See below for a list of known issues in this beta release.

ESP-IDF v3.3-beta3 is a minor update for ESP-IDF v3.2.x. Release v3.3-beta3 is compatible with apps written for ESP-IDF v3.x, but features in v3.3-beta3 may not be available in earlier versions.

This is the list of changes since release v3.2:

Known Issues

  • WPS does not work properly
  • esp_smartconfig_stop not return under some rare circumstances
  • BT SPP may ASSERT when use with Wi-Fi
  • Watchdog timeout when using an RSA 4096-bit key to connect to WPA2-Enterprise (EAP-TLS) AP.

Major New Features

Wi-Fi Related

New Functionality

Bug Fixes

  • Reduced cases where Wi-Fi needs to listen for RX when waking from sleep state, depending on beacon contents
  • Fixed thread safety bug in WPS
  • Reduced IRAM usage of libnet80211.a
  • Fixed Wi-Fi baseband reset issue after baseband switched to 11b weak signal mode

  • Fixed STA HT20/40 coexist
  • Fixed compliance by disallowing WEP/TKIP with HT rates
  • Improved WPA2 support

ESP-MESH Related

New Functionality

Bug Fixes

  • Fixed failure of mesh stop caused by block-sending.
  • Fixed when FIXED_ROOT is set, 2nd layer devices can not receive mesh event ESP_ERR_MESH_NO_PARENT_FOUND.
  • Fixed when FIXED_ROOT is set and the root turns off mesh function, 2nd layer devices do not look for new parents.
  • Now disconnects from parent/router when the DSSS channel in received beacon is different from the home channel.

Wi-Fi/Bluetooth Coexistence Related

  • Reduced binary size when coexistence is not enabled, or if only BT is used
  • Fixed issue that spike transmit power of WiFi could be higher than configured when Bluetooth coexistence enabled

App Trace Related

System Related

New Functionality

Bug Fixes

  • Fixed a newlib crash if built with -O2 optimization level
  • When using section attributes (IRAM_ATTR, DRAM_ATTR, etc), now places each variable in a unique section - allows gc-sections to work, and prevents section type conflicts
