Key Features#

None

API Changes#

None

Bug Fixes#

  • Fixed rsi_ble_connect_cancel() handling to ensure that the connection callback reports error status 0x4E02, indicating that the ongoing BLE connection attempt was canceled.

  • Fixed an issue where rsi_ble_connect_cancel() returned error 0x4E0C when canceling a connection attempt without receiving a connection callback during extended advertising and scanning.
