Full Changelog: 1.4.0...1.4.1

BT5 and nRF5 support

[1.4.0] - 2022-07-10

Fixed

• Fixed missing data from long notification values.
• Fixed NimbleCharacteristicCallbacks::onRead not being called when a non-long read command is received.

Changed

• Updated NimBLE core to use the v1.4.0 branch of esp-nimble.
• AD flags are no longer set in the advertisements of non-connectable beacons, freeing up 3 bytes of advertisement room.

Added

• Preliminary support for non-esp devices, NRF51 and NRF52 devices supported with n-able arduino core
• Alias added for NimBLEServerCallbacks::onMTUChange to onMtuChanged in order to support porting code from original library.
• NimBLEAttValue Class added to reduce and control RAM footprint of characteristic/descriptor values and support conversions from Arduino Strings and many other data types.
• Bluetooth 5 extended advertising support for capable devices. CODED Phy, 2M Phy, extended advertising data, and multi-advertising are supported, periodic advertising will be implemented in the future.

Release 1.3.8

Fixed

• Fix compile error with ESP32S3.
• Prevent a potential crash when retrieving characteristics from a service if the result was successful but no characteristics found.

Changed

• Save resources when retrieving descriptors if the characteristic handle is the same as the end handle (no descriptors).
• Subscribing to characteristic notifications/indications will now always use write with response, as per BLE specifications.
• NimBLEClient::discoverAttributes now returns a bool value to indicate success/failure

1.3.7

Fixed

• Crash when retrieving an attribute that does not exist on the peer.
• Memory leak when deleting client instances.
• Compilation errors for esp32s3

1.3.6

Changed

• When retrieving attributes from a server fails with a 128bit UUID containing the ble base UUID another attempt will be made with the 16bit version of the UUID.

Fixed

• Memory leak when services are changed on server devices.
• Rare crashing that occurs when BLE commands are sent from ISR context using IPC.
• Crashing caused by uninitialized disconnect timer in client.
• Potential crash due to unintialized advertising callback pointer.

1.3.5

[1.3.5] - 2022-01-14

Added

• CONFIG_NIMBLE_CPP_DEBUG_LEVEL macro in nimconfig.h to allow setting the log level separately from the Arduino core log level.

Fixed

• Memory leak when initializing/deinitializing the BLE stack caused by new FreeRTOS timers be created on each initialization.

1.3.4

• Workaround for latest Arduino-esp32 core that causes tasks not to block when required, which caused functions to return prematurely resulting in exceptions/crashing.
• The wrong length value was being used to set the values read from peer attributes. This has been corrected to use the proper value size.

Full Changelog: 1.3.3...1.3.4

1.3.3

Workaround added for FreeRTOS bug that affected timers, causing scan and advertising timer expiration's to not correctly trigger callbacks.

1.3.2

• Added missing macros for scan filter.
• Added NimBLEClient::getLastError : Gets the error code of the last function call that produces a return code from the stack.
