Specifications

GOODOCOM Technologies Confidential GOC-BA440 Specification
GOODOCOM Technologies Confidential 6
 High-speed HCI UART transport support with low-power out-of-band BT_DEV_WAKE and
BT_HOST_WAKE signaling (see Host Controller Power Management)
 Channel quality driven data rate and packet type selection
 Standard Bluetooth test modes
 Extended radio and production test mode features
 Full support for power savings modes
 Bluetooth clock request
 Bluetooth standard sniff
 Deep-sleep modes and software regulator shutdown
 Supports a low-power crystal, which can be used during power save mode for better timing
accuracy.
3.2.1 Bluetooth 4.0 Features
The BBC supports all Bluetooth 4.0 features, with the following benefits:
 Dual-mode Bluetooth Low Energy (BT and BLE operation)
 Extended Inquiry Response (EIR): Shortens the time to retrieve the device name, specific profile, and
operating mode.
 Encryption Pause Resume (EPR): Enables the use of Bluetooth technology in a much more secure
environment.
 Sniff Subrating (SSR): Optimizes power consumption for low duty cycle asymmetric data flow,
which subsequently extends battery life.
 Secure Simple Pairing (SSP): Reduces the number of steps for connecting two devices, with minimal
or no user interaction required.
 Link Supervision Time Out (LSTO): Additional commands added to HCI and Link Management
Protocol (LMP) for improved link time-out supervision.
 QoS enhancements: Changes to data traffic control, which results in better link performance. Audio,
human interface device (HID), bulk traffic, SCO, and enhanced SCO (eSCO) are improved with the
erroneous data (ED) and packet boundary flag (PBF) enhancements.
 Complies with Bluetooth Core Specification Version 5.0+2.1+BLE with provisions for supporting
future specifications.
3.2.2 Bluetooth 4.2 Features
The BBC supports all Bluetooth 4.2 features, with the following benefits:
 Dual-mode classic Bluetooth and classic low energy (BT and BLE) operation
 Low-energy physical layer
 Low-energy link layer
 Enhancements to HCI for low energy
 Low-energy direct test mode
 128 AES-CCM secure connection for both BT and BLE
 LE Data Packet Length Extension
 LE Secure Connections
Note: The CYW43455 is compatible with the Bluetooth Low Energy operating mode, which provides a
dramatic reduction in the power consumption of the Bluetooth radio and baseband. The primary
application for this mode is to provide support for low data rate devices, such as sensors and remote
controls.
3.2.3 Bluetooth Low Energy
supports the Bluetooth Low Energy operating mode.
3.2.4 Bluetooth 5.0
