Class 1 Bluetooth v2.0 Module User’s Guide USB Signal Levels.vdd_usb refers to the internal voltage generated by the LDO regulator on the module, which is typically 3.3 V. Hence 0.3vdd_usb and 0.7vdd_usb correspond to 1.0 V to 2.3 V. To achieve 3.3V for vdd_usb requires VCC_IN of 3.5V. USB IO voltage levels follows VCC_3V3. For correct USB operation, would require vdd_usb on 3.1V which requires of VCC_IN of ~3.3V (0.2V LDO drop).
Class 1 Bluetooth v2.0 Module User’s Guide 4. IO CHARACTERISTICS 4.1 Power Consumption The current drain from the VCC power input line is dependent on various factors. The three most significant factors are the voltage level at VCC, UART baud rate, and the operating mode. The hardware specification for the module allows for a voltage range of 3.0 to 5.0 at VCC.
Class 1 Bluetooth v2.0 Module User’s Guide 5. FUNCTIONAL DESCRIPTION The BT730 Bluetooth module is a self-contained Bluetooth product and requires only power to implement full Bluetooth communication. The integrated, high performance antenna, together with the RF and baseband circuitry provides the Bluetooth wireless link and the UART interface provides a connection to the host system.
Class 1 Bluetooth v2.0 Module User’s Guide BT730 Application - Host UART_TX /RXD UART_RX /TXD UART_CTS /RTS UART_RTS /CTS UART_DSR /DTR UART_DTR /DSR UART_RI /RING UART_DCD /DCD Note: The serial module output is at 3.3 V CMOS logic levels. Level conversion must be added to interface with an RS-232 level compliant interface. Some serial implementations link CTS and RTS to remove the need for handshaking. Laird does not recommend linking CTS and RTS other than for testing and prototyping.
Class 1 Bluetooth v2.0 Module User’s Guide 5.4 General Purpose I/O and ADC 5.4.1 GPIO Seven lines of programmable bi-directional input/outputs (I/O) are provided that can be accessed either via the UART port, or Over The Air (OTA) from a second Bluetooth unit. These can be used as data inputs or to control external equipment. By using these in OTA mode, a BT730 module can be used for control and data acquisition without the need for any additional host processor.

Class 1 Bluetooth v2.0 Module User’s Guide 6.3.1 ^^^{Enter Local Command Mode} When in data and connected mode, the host can force the device into a command and connected mode so that AT commands can be issued to the device. The character in this escape sequence is specified in the S2 register, therefore it can be changed. In addition, the escape sequence guard time is specified by S Register 12. By default the guard time is set to 100 milliseconds. Refer to Section 6.
Class 1 Bluetooth v2.0 Module User’s Guide Due to a known issue in the Bluetooth RFCOMM stack, it is not possible to make more than 65525 outgoing connections. Therefore if that number is exceeded, then the connection attempt fails with the following response: Response: CALL LIMIT Or NO CARRIER In that case, issuing an ATZ to reset the device resets the count to zero and allows more connections.
Class 1 Bluetooth v2.0 Module User’s Guide Response: CONNECT 123456789012 AE Or NO CARRIER 6.3.7 ATDR{Make Connection to peer specified in AT+BTR} Make a connection with the device address specified in the most recent AT+BTR command. The service is as specified in S Register 101. The modifiers are optional. An error is returned if the ‘R’ modifier is specified as well as a Bluetooth address. If both ‘R’ and ‘L’ modifiers are specified then an error is returned.

Class 1 Bluetooth v2.0 Module User’s Guide 8.6.16 Usage: Get File (Short Filename) Note: After each !command, if a +NN response is not received after 2 seconds, the host can repeat that command. The response to ! is “+NN” instead of just “NN” to make easier for the host to predict the command, since on completion the standard response is “200 FTP” which also happens to start with a number. The ‘+’ shall be early warning to the host that the procedure is not complete.
Class 1 Bluetooth v2.0 Module User’s Guide 8.6.17 Usage: Get File (Empty file in server) Note: If the file size is 0, then the host shall receive “200 FTP” instead of “200 GET”. The latter is invitation to the host that data needs to be marshalled across.

Class 1 Bluetooth v2.0 Module User’s Guide 8.6.19 Usage: Get File – ABORT Note: If “200 FTP” is received after submitting an ABORT command then it implies that the entire file was transferred before the abort had been received. Figure 21: Get file - ABORT 8.6.20 Usage: Unsuccessful FTP connection Note: Reason for connection failure could be: Device is not in range Device is not connectable Device does not support FTP server profile.
Class 1 Bluetooth v2.0 Module User’s Guide 8.6.21 Usage: ABORT a DIR request Note: The host may get more file/folder names after submitting an ABORT request because the device could have received a folder data OBEX packet at the same time but slightly earlier so it may have started processing it. Hence the host must look out for a “200 FTP” to be sure that the DIR operation has terminated. Some ftp servers (like widcomm stack) will return a 500 response code.
Class 1 Bluetooth v2.0 Module User’s Guide 9. OBEX PROFILE COMMANDS This section describes the OBEX implementation on BTM430/431 which allows performing the role of ‘Obex Push Client’ as illustrated in the diagram below. Figure 24: OBEX Push client and server The Obex Push profile implementation provides the capability to a host to act as an ‘Obex Push client’ to a peer device providing an ‘obex push server’ profile.
Class 1 Bluetooth v2.0 Module User’s Guide 9.2 nnn shall be a decimal number with at least one digit. The backspace character is not supported. All OBEX commands are case sensitive. OBEX Commands shall not exceed 32 characters in total. While an OBEX session is open, the host shall not deassert the modules UART_CTS line and conversely the host MUST always be ready to accept data. When Unicode data is transmitted, it shall be assumed that the most significant byte is transmitted first.
Class 1 Bluetooth v2.0 Module User’s Guide 9.3.2 PUT –nnnlength(Send file) This OBEX subcommand is used to send a file to the OBEX push server where the filename is in UNICODE text and the filename is –nnn bytes long. The length value is inserted into the OBEX length header field. See comment above with regards to S Reg 582 TBC. 9.3.3 ABORT(Abort current OBEX command) This OBEX subcommand is used to abort a file transfer where appropriate.

Class 1 Bluetooth v2.0 Module User’s Guide 9.5.3 ! This command is used to ask the module/host how many bytes of data it will send next. If the module/host sends a length value that is too large to hanlde, then it can be rejected by resending the !command. This is because accepting a value implies this end should send a ? prompt to trigger the data phase (see Section 9.5.4). 9.5.
