1.3.0

Added

• NimBLECharacteristic::removeDescriptor: Dynamically remove a descriptor from a characterisic. Takes effect after all connections are closed and sends a service changed indication.

• NimBLEService::removeCharacteristic: Dynamically remove a characteristic from a service. Takes effect after all connections are closed and sends a service changed indication

• NimBLEServerCallbacks::onMTUChange: This is callback is called when the MTU is updated after connection with a client.

• ESP32C3 support

• Whitelist API:

  • NimBLEDevice::whiteListAdd: Add a device to the whitelist.
  • NimBLEDevice::whiteListRemove: Remove a device from the whitelist.
  • NimBLEDevice::onWhiteList: Check if the device is on the whitelist.
  • NimBLEDevice::getWhiteListCount: Gets the size of the whitelist
  • NimBLEDevice::getWhiteListAddress: Get the address of a device on the whitelist by index value.

• Bond management API:

  • NimBLEDevice::getNumBonds: Gets the number of bonds stored.
  • NimBLEDevice::isBonded: Checks if the device is bonded.
  • NimBLEDevice::deleteAllBonds: Deletes all bonds.
  • NimBLEDevice::getBondedAddress: Gets the address of a bonded device by the index value.

• NimBLECharacteristic::getCallbacks to retrieve the current callback handler.

• Connection Information class: NimBLEConnInfo.

• NimBLEScan::clearDuplicateCache: This can be used to reset the cache of advertised devices so they will be immediately discovered again.

Changed

• FreeRTOS files have been removed as they are not used by the library.
• Services, characteristics and descriptors can now be created statically and added after.
• Excess logging and some asserts removed.
• Use ESP_LOGx macros to enable using local log level filtering.

Fixed

• NimBLECharacteristicCallbacks::onSubscribe Is now called after the connection is added to the vector.
• Corrected bonding failure when reinitializing the BLE stack.
• Writing to a characterisic with a std::string value now correctly writes values with null characters.
• Retrieving remote descriptors now uses the characterisic end handle correctly.
• Missing data in long writes to remote descriptors.
• Hanging on task notification when sending an indication from the characteristic callback.
• BLE controller memory could be released when using Arduino as a component.
• Complile errors with NimBLE release 1.3.0.
