data and UART_CTS and UART_RTS can be used to implement RS232hardware flow control where both are active low indicators.The interface consists of four-line connection as described in below:Signal name

EvenNumber of Stop Bits1Default Data FormatPCM InterfaceBluetooth module offers a bi-directional digital audio interface that routes directly into the basebandlayer and does not pass through the HCI protocol layer.It allows the data to be sent to and recevied from a SCO connectionThis interface consists of four signals:a clock(PCM_CLK),a data input(PCM_IN),a data output(PCM_OUT),and a frame-synchronization signal(PCM_SYNC)Bluetooth module interfaces directly to PCM audio devices including the following:-Qualcomm MSM3000series and MSM5000series CDMA baseband devices-OKI MSM7705four channel A-law and u-low CODEC-Motorola MC1454818-bit A-law and u-law CODEC-Motorola MC14548313-bit linear CODECPCM settingsBluetooth module can operate as the PCM interface master generating an output clock of 256kHz.When configured as PCM interface slave it can operate with input clock up to2048kHz.User can change data format the following selection using PSKEY.Property Possible ValuesMode

Possible ValuesMode MasterClock rate256kHzClock formats Long Frame SyncSample formats13-bit linearUART Bypass Mode-For devices that do not tri-state the UART bus,the UART bypass mode on bluetoothmodule can be used.-The default state of the module after reset is de-asserted is for the host UART bus to be connected to its UART.-In order to apply the UART bypass mode,a BCCMD command will be issued to themodule upon this,it will switch the bypass to PIO(4,5,6,7).Once the bypass mode has been invoked,it will enter the deep sleep state indefinitely.-In order to re-establish communication with the module,it must be reset so that thedefault configuration takes affect.-It is important for the host to ensure a clean bluetooth disconnection of any active links before the bypass mode is invoked.Therefore it is not possible to have active Bluetooth links while operating the bypass mode.Package DimensionsUnit:mm。
