2.3.2

Fixed

• Max connections not being applied correctly above 4.
• Build errors with arduino cores using IDF v4.x
• onConnect callback not being called when the status is BLE_ERR_UNSUPP_REM_FEATURE, workaround for upstream issue.

Changed

• FreeRTOS port uses the old porting layer for all but the latest esp32 mcus.
• By default BLE secure connections is disabled now to reduce issues when it's enabled but not used by the application.
• BLE mesh files are now only compiled if mesh is enabled in the project configuration.

Full Changelog: 2.3.0...2.3.1

2.3.0

Fixed

• Incorrect NimBLECharacteristic::onSubscribe value when indications are set.
• NimBLECharacteristic::onRead callback not called in some cases.
• Clear attribute value when zero length value is written.
• Notify/Indicate incorrectly returning success with custom value.
• Corrected NimBLEClient array initialization.
• Prevent potential exception when scan is restarted.
• Attribute getValue failing with some data types
• Incorrectly passing a pointer to a function taking const reference.

Added

• Support for esp32c2, esp32c5, esp32c6, esp32h2
• L2CAP infrastructure.
• Scan duplicate cache reset time.

Changed

• Cleaned up examples.
• Update nimble core to esp-nimble @70439dd.
• Disable flow control for all targets except original esp32.
• Allow PHY updates without enabling extended advertising.
• Reduced iram usage

2.2.3

Fixed

• Added back NimBLEClient::connect overload with NimBLEAdvertisedDevice parameter to resolve connection error due to NULL address.
• Crash caused by returning invalid vector entry when retrieving remote descriptors.

2.2.2

Fixed

• Crash when calling NimBLEClient::DiscoverAttributes.

Added

• NimBLEDeviceCallbacks class with a callback for handling bond storage.

2.2.1

Fixed

• remote descriptor discovery error when no descriptors exist.
• scan filter settings not enabled for esp32s3/c3.
• remote descriptor discovery returning more than the desired descriptor.

2.2.0

Fixed

• Crash when retrieving descriptors if more than one exists.
• Incorrect TX power value being advertised.
• New user guide code for 2.x
• Potential race condition if `NimBLEScan::clearResults1 is called from multiple tasks.

Changed

• If privacy is not enabled identity keys will not be shared.
• NimBLEDevice::setPower and NimBLEDevice::getPower now take an additional parameter NimBLETxPowerType to set/get the power level for different operations.
• ESP32 devices now use esp_timer instead of freeRTOS timers for BLE operations by default.

Added

• Config option to use mbedtls instead of tinycrypt for crypto operations, this will save approximately 8k of flash if already using mbedtls for other applications (https, mqtts, etc..).
• Config option CONFIG_NIMBLE_CPP_ADDR_FMT_EXCLUDE_DELIMITER, if defined will remove the ":" delimiter from the BLE address string.
• Config option CONFIG_NIMBLE_CPP_ADDR_FMT_UPPERCASE if defined will make the BLE address strings uppercase.
