# Changelog
All notable changes to this project will be documented in this file.
## Unreleased changes.
### Fixed
- Initialize advertising complete callback in NimBLEAdvertising constructor.
- Clear client disconnect timer in constructor before initializing.
- Fix missing data when reading large values.
- Fix missing data in notifications when using a large MTU size and more than 270 bytes of data are sent.
- Workaround fix added for cases when the task notification value is not cleared, causing various functions that should block not to block.
### Added
- `NimBLEClient::getLastError` : Gets the error code of the last function call that produces a return code from the stack.
- `NimBLECharacteristic::notify` : Overload method to send notifications/indications with custom values.
- Added conditional checks for ESP32 specific functions/values to support use of the library on non-esp32 devices.
- Added an alias to use the callback name from the original library `onMtuChanged`.
### Changed
- Critical section calls now use the NimBLE API instead of FreeRTOS directly. This removes the need for a `portMUX_TYPE` variable in the class definitions.
- Removed unnecessary variables in `NimBLEService` and changed the constructor no no longer accept `numHandles` and `inst_id` parameters.
## [1.3.1] - 2021-08-04
### Fixed
- Corrected a compiler/linker error when an application or a library uses bluetooth classic due to the redefinition of `btInUse`.
## [1.3.0] - 2021-08-02
### 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

### 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.

### Changed
- `nimconfig.h` (Arduino) is now easier to use.
- `NimBLEServer::getServiceByUUID` Now takes an extra parameter of instanceID to support multiple services with the same UUID.
- `NimBLEService::getCharacteristic` Now takes an extra parameter of instanceID to support multiple characteristics with the same UUID.
- `NimBLEAdvertising` Transmission power is no longer advertised by default and can be added to the advertisement by calling `NimBLEAdvertising::addTxPower`
- `NimBLEAdvertising` Custom scan response data can now be used without custom advertisment.
- `NimBLEScan` Now uses the controller duplicate filter.
- `NimBLEAdvertisedDevice` Has been refactored to store the complete advertisement payload and no longer parses the data from each advertisement.
Instead the data will be parsed on-demand when the user application asks for specific data.
### Fixed
- `NimBLEHIDDevice` Characteristics now use encryption, this resolves an issue with communicating with devices requiring encryption for HID devices.
## [1.1.0] - 2021-01-20
### Added
- `NimBLEDevice::setOwnAddrType` added to enable the use of random and random-resolvable addresses, by asukiaaa
- New examples for securing and authenticating client/server connections, by mblasee.
- `NimBLEAdvertising::SetMinPreferred` and `NimBLEAdvertising::SetMinPreferred` re-added.
- Conditional checks added for command line config options in `nimconfig.h` to support custom configuration in platformio.
- `NimBLEClient::setValue` Now takes an extra bool parameter `response` to enable the use of write with response (default = false).
- `NimBLEClient::getCharacteristic(uint16_t handle)` Enabling the use of the characteristic handle to be used to find
the NimBLERemoteCharacteristic object.
- `NimBLEHIDDevice` class added by wakwak-koba.
- `NimBLEServerCallbacks::onDisconnect` overloaded callback added to provide a ble_gap_conn_desc parameter for the application
to obtain information about the disconnected client.
- Conditional checks in `nimconfig.h` for command line defined macros to support platformio config settings.
### Changed
- `NimBLEAdvertising::start` now returns a bool value to indicate success/failure.
- Some asserts were removed in `NimBLEAdvertising::start` and replaced with better return code handling and logging.
- If a host reset event occurs, scanning and advertising will now only be restarted if their previous duration was indefinite.
- `NimBLERemoteCharacteristic::subscribe` and `NimBLERemoteCharacteristic::registerForNotify` will now set the callback
regardless of the existance of the CCCD and return true unless the descriptor write operation failed.
- Advertising tx power level is now sent in the advertisement packet instead of scan response.
- `NimBLEScan` When the scan ends the scan stopped flag is now set before calling the scan complete callback (if used)
this allows the starting of a new scan from the callback function.
### Fixed
- Sometimes `NimBLEClient::connect` would hang on the task block if no event arrived to unblock.
A time limit has been added to timeout appropriately.
- When getting descriptors for a characterisic the end handle of the service was used as a proxy for the characteristic end
handle. This would be rejected by some devices and has been changed to use the next characteristic handle as the end when possible.
- An exception could occur when deleting a client instance if a notification arrived while the attribute vectors were being
deleted. A flag has been added to prevent this.
- An exception could occur after a host reset event when the host re-synced if the tasks that were stopped during the event did
not finish processing. A yield has been added after re-syncing to allow tasks to finish before proceeding.
- Occasionally the controller would fail to send a disconnected event causing the client to indicate it is connected
and would be unable to reconnect. A timer has been added to reset the host/controller if it expires.
- Occasionally the call to start scanning would get stuck in a loop on BLE_HS_EBUSY, this loop has been removed.
- 16bit and 32bit UUID's in some cases were not discovered or compared correctly if the device
advertised them as 16/32bit but resolved them to 128bits. Both are now checked.
- `FreeRTOS` compile errors resolved in latest Ardruino core and IDF v3.3.
- Multiple instances of `time()` called inside critical sections caused sporadic crashes, these have been moved out of critical regions.
- Advertisement type now correctly set when using non-connectable (advertiser only) mode.
- Advertising payload length correction, now accounts for appearance.
- (Arduino) Ensure controller mode is set to BLE Only.
## [1.0.2] - 2020-09-13
### Changed
- `NimBLEAdvertising::start` Now takes 2 optional parameters, the first is the duration to advertise for (in seconds), the second is a
callback that is invoked when advertsing ends and takes a pointer to a `NimBLEAdvertising` object (similar to the `NimBLEScan::start` API).
- (Arduino) Maximum BLE connections can now be altered by only changing the value of `CONFIG_BT_NIMBLE_MAX_CONNECTIONS` in `nimconfig.h`.
Any changes to the controller max connection settings in `sdkconfig.h` will now have no effect when using this library.
- (Arduino) Revert the previous change to fix the advertising start delay. Instead a replacement fix that routes all BLE controller commands from
a task running on core 0 (same as the controller) has been implemented. This improves response times and reliability for all BLE functions.
## [1.0.1] - 2020-09-02
### Added
- Empty `NimBLEAddress` constructor: `NimBLEAddress()` produces an address of 00:00:00:00:00:00 type 0.
- Documentation of the difference of NimBLEAddress::getNative vs the original bluedroid library.
### Changed
- notify_callback typedef is now defined as std::function to enable the use of std::bind to call a class member function.
### Fixed
- Fix advertising start delay when first called.
## [1.0.0] - 2020-08-22
First stable release.
All the original library functionality is complete and many extras added with full documentation.
