ESP-IDF v3.2 is a minor update for ESP-IDF v3.1.x. Release v3.2 is compatible with apps written for ESP-IDF v3.1.x, but features in v3.2 may not be available in earlier versions.

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

Known Issues

  • Watchdog timeout when using an RSA 4096-bit key to connect to WPA2-Enterprise (EAP-TLS) AP.
  • ESP32 SoftAP mode may fail to deliver multicast packets to stations which have power save modes enabled.

Major New Features

Breaking Changes

  • RMT peripheral: Removed incorrect rmt_item16_t register access type. Use existing rmt_item32_t instead.

Changes not compatible with earlier versions

These changes do not require any action when updating to V3.2, but will require consideration if moving from V3.2 to an earlier version.

  • NVS: Support has been added for NVS blobs larger than 1984 bytes. NVS partitions created from earlier ESP-IDF versions will be automatically updated when written from ESP-IDF V3.2. NVS partitions written from ESP-IDF V3.2 are not compatible with the NVS format used by earlier versions of ESP-IDF. It is possible to support the updated NVS partition format in ESP-IDF v3.1.x via the "Enable multi-page blob support" config option.

v3.2-beta3 is a prerelease of ESP-IDF v3.2. See below for a list of known issues in this beta release.

ESP-IDF v3.2 is a minor update for ESP-IDF v3.1.x. Release v3.2 is compatible with apps written for ESP-IDF v3.1.x, but features in v3.2 may not be available in earlier versions.

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

Known Issues

  • Bluetooth modem sleep may infrequently cause BLE scans to fail until next reset
  • Rare ASSERT or crash caused by BLE connect/scan/adv when Wi-Fi triggers lots of interrupts (for example, Wi-Fi is running a throughput test) or high priority task swtich (equal to or greater than Bluetooth controller task priority).
  • Rare ASSERT or crash caused by BLE scan/adv stop or disconnect because memory corrupted in BLE controller memory pool.
  • BLE controller will ASSERT during scan if host is not able to handle adv reports in time (for example, application is printing a lot of logs so CPU can't process adv reports).
  • If LWIP Auto IP is enabled, switching Wi-Fi mode will cause a memory leak.
  • Watchdog timeout when using an RSA 4096-bit key to connect to WPA2-Enterprise (EAP-TLS) AP.
  • SoftAP mode doesn't support Wi-Fi power save. Stations with Wi-Fi power save enabled could lose some packets sent from SoftAP.
  • Rare memory leak in Wi-Fi Mesh
  • FreeRTOS xPortGetCoreID() function may return wrong core on un-pinned tasks
  • Rare crash in mDNS
  • When system is printing to an unbuffered stream, mesh task stack overflow may occur

Major New Features

Breaking Changes

  • RMT peripheral: Removed incorrect rmt_item16_t register access type. Use existing rmt_item32_t instead.
  • ESP-MESH: When Mesh IE encryption is enabled, Mesh V3.1 devices cannot connect to Mesh V3.2 devices. Devices with unencrypted Mesh IE can connect between versions, although features added in V3.2 will not work well in a mixed-version mesh.

Changes not compatible with earlier versions

These changes do not require any action when updating to V3.2, but will require consideration if moving from V3.2 to an earlier version.

  • NVS: Support has been added for NVS blobs larger than 1984 bytes. NVS partitions created from earlier ESP-IDF versions will be automatically updated when written from ESP-IDF V3.2. NVS partitions written from ESP-IDF V3.2 are not compatible with the NVS format used by earlier versions of ESP-IDF. It is possible to support the updated NVS partition format in ESP-IDF v3.1.x via the "Enable multi-page blob support" config option.
  • Wear Levelling: Wear Levelling flash partition format has been updated to Version 2, to support flash encryption. Version 1 Wear Levelling partitions will be automatically updated to Version 2. Version 2 partitions are not compatible with ESP-IDF V3.1.x or earlier.

Wi-Fi Related

  • Added internal API to enable or disable transmitting WiFi MAC frame with fixed rate.
  • Fixed bug that ESP32 crashes because of WiFi static TX buffer alloc/free.
  • Enabled Soft-AP receiving BAR to fix the issue that iphone fails to connect to Soft-AP.
  • Fixed the issue that STA fails to connect to some APs after reset.
  • wpa_supplicant: Implemented BIGNUM and ECC crypto wrapper apis for ESP using mbedtls.
  • Fixed the index of the invalid channel state information(CSI) data.
  • Corrected a mistake of CSI sub-carrier index in Wi-Fi documentation.

Smartconfig Related

  • Added support for broadcast packets sent by newer versions of ESP-TOUCH (useful for 5GHz router compatibility). Multicast packets sent by earlier versions of ESP-TOUCH are also still supported.
  • Fixed the declaration of remote_ip in sc_ack_send_task()

ESP-MESH Related

  • Note: When Mesh IE encryption is enabled, Mesh V3.1 devices cannot connect to Mesh V3.2 devices. Devices with unencrypted Mesh IE can connect between versions, although features added in V3.2 will not work well in a mixed-version mesh.

New Functionality

  • Removed dependencies which cause mesh code to be linked even if mesh is not used
  • Dynamically malloc the routing table
  • Support for not configuring the network channel
  • Support not configuring the router BSSID even if the router is hidden

  • Automatically detect and resolve root conflicts when router BSSID is not set
  • Modify the max routes limitation from 300 to 1000
  • Add an event MESH_EVENT_NETWORK_STATE that contains information about whether there is a root in the current network
  • Add APIs esp_mesh_disconnect() and esp_mesh_connect()
  • RAM usage reduced 3KB RAM by removing an unnecessary task

Fixes

  • Fixed STAs can not detect disconnection from AP when encrypt transmission is used
  • Fixed memory leak when esp_mesh_stop() is called, the memory occupied by the transmitting remove announcement is not released
  • esp_mesh_connect() will be ignored if mesh automatic reconnection is enabled
  • Fixed vote reason is cleared before vote is done
  • Fixed issues in the example of manual_networking when mesh network is encrypted
  • When root can not connect to the router due to NO_MORE_STAS (reason code:5), root will stop re-connection and perform MESH_NWK_LOOK_FOR_NETWORK
  • Fixed disconnection caused by receiving a deauth frame from non-parent node during scanning
  • Fixed routing table redundant issue due to remove announcing is not 100% reliable
  • Fixed when a STA has not yet completed the 4-way handshake but the max replay count is reached, AP does not deauth the STA
  • New logic: During parent selection, the AP which is found without extended associated IE will be considered it has the same router BSSID as device itself
  • When STA leaves from AP, AP will now always post SYSTEM_EVENT_AP_STADISCONNECTED to mesh layer regardless of whether the STA has passed the encrypted authentication or not
  • Fixed ap_loss that occurs when the parent turns off the mesh function and becomes a normal Wi-Fi with a different SSID
  • Fixed in the process of re-voting to select the root, the device votes for itself even though it does not meet the conditions of being a root
  • Fixed issues in esp_mesh_recv_toDS() when stopping the mesh
  • When the user specifies a parent for the device, the device will now set the authmode and password of its Soft-AP mode to the same value as the specified parent
  • 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
