commit
603fec95a8
@ -13,7 +13,8 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
|
||||
- AVRCP Controller: Added send generic PASS THROUGH command
|
||||
- HID Host: storage for HID Descriptors is now optional
|
||||
- HCI: support newer AIROC Controller that require Download Mode with ENABLE_AIROC_DOWNLOAD_MODE
|
||||
|
||||
- Zephyr: provide hal_flash_bank implementation for native flash driver
|
||||
|
||||
### Fixed
|
||||
- GAP: store link key for standard/non-SSP pairing
|
||||
- BENP: emit channel opened with ERROR_CODE_REMOTE_USER_TERMINATED_CONNECTION if connection cannot be set up
