Major changes

This is the list of changes since release v5.3:

Major New Features

  • Wi-Fi: Added FTM calibration values for ESP32-C6 (e990d1e)
  • Wi-Fi: Supported lower coexistence power consumption when Wi-Fi disconnects from AP (5a5c004)
  • ESP Bluedroid Host: Added support of Cover Art feature in AVRCP Controller (cda2846)
  • ESP Bluedroid Host: Added support of Device Identification Profile (ca05aa5)
  • Bootloader: Added mocks for bootloader_support component (90cc261)
  • Power Management: Added support for PSRAM retention in light sleep on ESP32-P4(82e76ab)
  • Peripheral Drivers: Added support for sleep retention of several peripherals in light sleep on ESP32-C6 and H2
  • ULP: Added LP core debugging support (a07eed6)
  • I2C: Support lp i2c instance on ESP32-P4 (ec3029e)
  • ISP: Support a series of ISP features on ESP32-P4
  • LCD: Added i80 LCD driver support on ESP32-P4 (fdd90d4)
  • Touch Sensor: Touch Driver-NG on ESP32-P4 (c23165b)
  • MbedTLS: Support ESP32-C2 rev2.0 ROM mbedtls-v3.6.0 (9a47de5)
  • System Hardware: Supported ESP32-C2 chip rev2.0 (e43ded7)
  • PSRAM: Supported APS3204L (cb9f474)
  • Thread: Supported Thread Radio Encapsulation Link (TREL) feature (d1ef423)

Breaking Changes

  • Core System: Renamed __VA_NARG__ and its macros to be prefixed with ESP_, i.e. __VA_NARG__ to ESP_VA_NARG to avoid naming collisions. If using these then update to use the new name. (bb8fa93)
  • Security / ESP Cert Bundle: Due to changes in the certificate bundle format to reduce RAM usage, the use of pre-generated certificate bundles using the older format would now be incompatible with the newer application binaries. You now need to either use the default ESP-IDF build system method for attaching the certificate bundle while building applications or update your pre-generated certificate bundle binaries by generating them using the latest gen_crt_bundle.py script. (fa4c387)
  • SDMMC: Function sdmmc_host_init no longer returns ESP_ERR_INVALID_STATE when the SDMMC host is already initialized, now it returns ESP_OK. (d1571c1)
  • SPI Flash: Removed XMC-C suspend support because there is risk that erase operation might never finish (121a272)
  • Wi-Fi: Removed the definition of the "WIFI_BAND_2G_5G" field in "wifi_band_t". (7b5014a)
  • ESP Bluedroid Host: Added new Kconfig option to enable SDP APIs and remove the dependency of SDP on L2CAP Kconfig option
  • LWIP / PPP: PPPoS internal callback function has incompatible prototype. Please use esp_netif API or update your function callbacks. (d4f60fe)

Known Issues

  • BLE: An BLE assert may occur in the function r_ble_lll_rxbuffer_free_all under low-memory conditions on ESP32-H2.
  • For ESP32-C2 ECO4 chips, wifi_scan_threshold_t in wifi_sta_config_t structure is invalid.
  • For ESP32-C2 ECO4 chips, when the country policy is set to WIFI_COUNTRY_POLICY_AUTO, the station will not scan for channels outside current country rules.
  • Power Management: In light sleep mode, rejecting sleep due to a short duration can introduce an RTC clock error, causing esp_timer inaccuracies and potential Bluetooth disconnections.
  • For ESP32, Bluedroid Host memory leaks when HFP client or AG is enabled using HCI audio datapath.

Known issues are planned to be fixed before the final v5.4 release.

Known Issues

  • For ESP32-P4, under the dual-core PD_TOP sleep scenario, if the sleep request is rejected, it may lead to a system deadlock triggering the watchdog.
  • For ESP32-P4, RTC peripheral power domain cannot be powered down, resulting in ~20uA more power consumption.
  • For ESP32-P4, there is a probability that the watchdog will be triggered due to the mpll being disabled and the L2 Cache not being able to write back when the PSRAM is enabled to sleep.
  • For ESP32-P4, GPIO wake-up function and EXT1 wake-up function of GPIO8~15 are not available during deepsleep.
