Introduction BH661C is a dual mode BLE (Bluetooth Low Energy) and Bluetooth Classic module using Toshiba TC35661 SOC. TC35661 provides BluetoothTM HCI (Host Control Interface) function specified in BluetoothTM Core Specifications. The HCI function allows BH661 to be connected to an external host processor for Bluetooth applications. 2. Product Overview The following is a block diagram of Toshiba BH661. It communicates with a host processor via an UART port. A 26MHz main clock crystal is on board. For lower power consumption in sleep mode, an external 32.768 KHz clock source is required. This module can be wake up by an external signal An chip antenna is on board. For ROM code supporting wide band voice, use I2S interface to connect to an external codec.

UART Interface Features • • ✦ ✦ ✦ ✦ ✦ • Full duplex 4-wire data transfer: RX, TX, RTSX, CTSX. Programmable baud rate:2400 bps to 4.33 Mbps. Data format: LSB first 1 start bit 8 data bit 1 stop bit No parity bit Error detection: BlueFan BH661C, Dual Mode Bluetooth Module Ver 1.00July 2016 draft ✦ ✦ ✦ Character timeout Overrun error Framing error TC35661 UART interface is used to transfer control command and data and is multiplexed with GPIO pin. After to release reset state, TC35661 software sets UART interface to related GPIO pins.The default bit rate depends on the selection ROM version. (e.g. TC35661-503: 115,2kbps) Flow Control Function TC35661 UART interface uses flow control function by hardware signal, Transmit flow control (CTSX) and receive flow control (RTSX). Above Figure shows signals input and output direction . CTSX input signal is used for UART transmitting. Low input indicates close of the preparation of the other party to receive data and TC35661 executes UART transmitting data if there is data for transmission. In case of input high level, TC35661 stops transmitting by UART frame. RTSX input signal is used for UART receiving. Low output indicates request data transmission to UART transmitside device of the other party. TC35661 outputs Low level from RTSX when being able to receive data and prepares to receive data.Response time of UART transmitting and receiving for flow control signal depends on baud rate and internal process status of frame. It is from 1 frame to 4 frames. Response time of UART transmitting and receiving for flow control signal depends on baud rate and internal process status of frame. It is from 1 frame to 4 frame. UART Baud Rate Setting TC35661 UART interface has a programmable baud rate setting function. The UART baud rate can be set according to the following equation. The baud rate generating clock frequency is set to either 39 MHz or 52 MHz. The over-sampling number is set to an integer that range from 1 to 65535. UART Baud Rate = Baud rate generating clock frequency/(Over sampling number x dividing ratio) The following table shows examples of UART baud rate setting. The maximum actual baud rate is 4,333,333 bps.

Software Information Regarding Software Versions The version number of the embedded software can be read out by an extended HCI command. The extended HCI command class < HCI_M2_Message_Get >" allows the reading of the firmware version. PC and MAC software to send HCI commands to read module software version is available from http://www.fasntel.com. Software The module software offers both embedded Bluetooth HCI (Host Control Interface), extended HCI and TCU (Toshiba Control Unit) Command interfaces via the embedded UART interface (1) HCI commands are standard according to Bluetooth standard specifications. (2) Extended HCI commands are available for device control, such as RF control, BD_ADDR control, firmware version control, embedded IO control, maintenance tasks etc. Please refer to the “Extension HCI Command Document”. (3) The BH661-502 includes Toshiba TC35661 with ROM code 502 incorporating Bluetooth stack and SPP profile and BLE GATT profile. The profile application interface is described in the “SPP Command Interface Document” (about 14 commands) and the “Bluetooth Basic Management Command Interface Document” (about 46 commands). The related high level commands are called “TCU” commands.The “SPP Message Sequence Chart Document” and the “Bluetooth Management Message . Sequence Chart Document” describe the logical and sequential procedure to use those commands. (4) The BH661-008 includes Toshiba TC35661 with ROM code 008 incorporating Bluetooth Handsfree profile and Headset profile. The profile application interface is described in the “Bluetooth Basic Management Command Interface Document” (about 46 commands). The related high level commands are called “TCU” commands. (5) After RESET of the module, the module starts in HCI mode. The “Bluetooth LSI TC35661 Application Note” describes how to start the device and enter into “TCU” mode thereafter. (6) Toshiba offers SPP drivers, that allows a further abstraction towards the application software including SPP programming examples. This is documented in the “BT SPP API Specification”, the ”BT SPP Driver Specification” and the “BT SPP Application Note”. The“SPP API” offers a few high-level APIs for LSI initialization, connection setup and communication with a remote SPP device. The user has full control over all LSI features by utilizing the lower-level“SPP Drivers”. The drivers take care for issuing commands and data to the LSI and they handle the responses from the TC36661. The “Application Note” includes a SPP programming exampleand shows the integration with a RTOS.”All documents are available on respective Fanstel or Toshiba websites. 10 BlueFan BH661C, Dual Mode Bluetooth Module Ver 1.00July 2016 draft 8.
