User Manual

InBT-UART Bluetooth Dongle with UART interface Note; * This user manual describes methods and functions for using InBT-UART. * This product is a Bluetooth dongle using UART communication interface which shall be assembled into the InBody (Body composition analyzer) or BPBIO (Blood pressure monitor) manufactured by Biospace for supporting data communications between the InBody or BPBIO and a personal computer.
1. Overview This product is a Bluetooth dongle using the UART communication interface. It can only be controlled through a processor supporting UART communication and cannot be used by directly connecting to a USB port of the InBody (Body composition analyzer) and BPBIO (Blood pressure monitor) (1) Contents ① InBT-UART ② User’s Manual 2. Product Specifications Bluetooth Version 2.1 + EDR, Class 1 Internal antenna Frequency band 2.4GHz ISM band Operation range 200-400m Transmission strength +13 dBm Reception sensitivity -86 dBm Supported services Serial Port Protocol(SPP), Dial-up Networking Profile(DUN), OBEX Objext Push Profile(OPP), OBEX File Transfer Profile(FTP), Human Interface Device Profile(HID), Phone Book Access Profile(PBAP), Health Device Profile(HDP), Device Identification Profile(DI), Service Discovery Protocol(SDP) Bluetooth 2.1 supports AFH (Adaptive Frequency Hopping). AFH helps minimize Interference between WiFi and Bluetooth signals by automatically selecting communication channels not used by WiFi signals. Please keep in mind that AFH may not guarantee complete non-interference between WiFi and Bluetooth signals depending on the operating environment. This includes the number of devices used and the distances between them. Performance may vary by operating environment.
3. Usage of Bluetooth dongle using the UART communication interface. ※ The Bluetooth dongle using the UART communication interface, InBT-UART shall be assembled inside of InBody (Body composition analyzer) or BPBIO (Blood Pressure Monitor) as following picture and measured data will be transferred to a personal computer, or external device has Bluetooth function. InBT-UART
(1) Hardware Pin Map Please refer this pin map of InBT-UART for designing your hardware 1 : Vcc (requires supply of 3.3V or higher) 2 : RxD 3 : TxD 4 : GND (2) UART settings Please set asynchronous communication in your hardware controller for communication with InBT-UART. * The following default UART settings are used for InBT-UART. - Baud rate : 115200 bps - Data bits : 8 - Stop bits : 1 - Parity bit : No parity - HW flow control : Disable (3) ASCII control commands After UART setting, please control the InBT-UART using the ASCII commands below. Provided below are instructions for using basic ASCII commands. For more information on the examples and instructions for using other commands, contact Biospace. - AT command This command is used for testing operation of the InBT-UART firmware. The command returns OK to indicate normal operation. - SET command AT OK
This command is used for retrieving or modifying the InBT-UART settings.
- Retrieving settings - Modifying settings In the following example, the Bluetooth PIN code required for pairing is set to “0000.” The code is saved in the non-volatile memory and only needs to be set once.

- INQUIRY command This command is used for searching for other Bluetooth devices available for pairing within the operating range. - CALL command The CALL command is used for establishing Bluetooth connections. The CALL event indicates that a connection is being attempted the CONNECT event indicates that a connection has been established. - SET RESET command This command is used for resetting the InBT-UART settings to factory defaults.

5. Troubleshooting (1) If connection is not good, try pairing the devices again. (2) Transferring data in large volumes may result in low performance depending on the device connected. (3) This product uses the same frequency bands as normal WiFi signals and is subject to ambient interferences. FCC Information This device complies with part 15 of the FCC Results. Operation is subject to the following two conditions : (1) This Device may not cause harmful interface, and (2) This device must accept any interference received, including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for CLASS B digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try correct the interference by one or more of the following measures: 1.1. Reorient or relocate the receiving antenna. 1.2. Increase the separation between the equipment and receiver. 1.3. Connect the equipment into an outlet on a circuit different from that to which receiver is connected. 1.4. Consult the dealer or experienced radio/TV technician for help. WARNING Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
