All notable changes to this project will be documented in this file.
## [1.3.3] - 2022-02-15
### Changed
- If attribute retrieval fails with a "not found" try again with the 16 bit version if a 128 bit base uuid is used.
### Fixed
- Memory leak when deleting client instance.
- IDf version check for data length extension.
- Memory leak when server services changed.
- Compiler warnings for non-esp32 devices.
## [1.3.2] - 2022-01-15
### 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`.
- `NimBLEClient::setDataLen` and `NimBLEServer::setDataLen`: Data length extension support (IDF version >= 4.3.2 only)
- Config option to set logging level for esp-nimble-cpp
### 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

# Bluetooth 5.x features
## About extended advertising
Extended advertising allows for much more capability and flexibility.
* Allows for 251 bytes of advertisement data and up to 1650 bytes when chained (configuration dependant) vs 31.
* New PHY's (physical layers) that allow for faster data rate (2M PHY) or long range/slower data rates (CODED PHY) as well as the original 1M PHY.
* New periodic advertising, allowing the scanning device to sync with the advertisements of a beacon. This allows for the scanning device to sleep or perform other tasks before the next expected advertisement is sent, preserving cpu cycles and power (To be implemented).
<br>
## Enabling extended advertising
Extended advertising is supported when enabled with the config option `CONFIG_BT_NIMBLE_EXT_ADV` set to a value of 1. This is done in menuconfig under `Component config > Bluetooth > NimBLE options >
Enable extended advertising`.
When enabled the following will occur:
* `NimBLEScan::start` method will scan on both the 1M PHY and the coded PHY standards automatically.
* `NimBLEClient::connect` will use the primary PHY the device is listening on, unless specified (see below).
* `NimBLEClient::setConnectPhy` becomes available to specify the PHY's to connect with (default is all).
* `NimBLEAdvertising` is no longer available for use and is replaced by `NimBLEExtAdvertising`. `NimBLEDevice::getAdvertising` will now return an instance of `NimBLEExtAdvertising`.
* `NimBLEAdvertisementData` is no longer available for use and is replaced by `NimBLEExtAdvertisement`. This new class is where everything about the advertisement is configured, including the advertisement intervals and advertisement ended callback.
