SOD-BT-210THE BT-210 IS AN UART SERIAL MODULE IMPLEMENTING BLUETOOTH COMMUNICATIONS STANDARDS

OEM Integrator manual [BT-210] Purpose The BT-210 is an UART serial module implementing Bluetooth communications standards. The module can connect to the following devices. (please refer to each controller on how to mount the BT-210.) • BT-210 : CM-100, CM-510, CM-530, CM-700, CM-900 [ examples of use] • Ollo Bug control via Bluetooth communications o Mount the BT-210 to the Bug’s controller (CM-100) o Connect a smartphone to the BT-210 and control the Bug • Control Bioloid Premium from a PC via Bluetooth o Mount a BT-210 to the CM-900 then connect to PC serially o Mount the BT-210 to Bioloid Premium’s controller (CM-510). Set-up • Connect the BT-210 to the CM-900 then run Tera Term. • Connect the CM-900 to the PC via US; install drivers; Tera Term terminal uses the actual COM port to connect ( pick any baud rate). Setup is now complete. baud rate can be of any value. <consult CM900_USB_드라이버설치.pdf for driver setup> • Go to Setup -> Terminal check Local echo. • From the terminal after AT input press the Enter key. With OK display then connection to BT-210 is successful. • The BT-210 and CM-900 will connect in a SLAVE/MASTER configuration. The following diagram is MASTER mode. • Instructions types From the terminal it is possible to change setup of the BT-210 via AT commands. ① System reset ATZ resets the BT-210. Any changes made the command will reset to the change(s) made. ② Mode change Use the command below to change the mode of the BT-210 (Slave/Master). AT+BTROLE=M -> Master mode AT+BTROLE=S -> Slave mode Then after ATZ command the system reset and mode change takes effect. <MASTER mode> <SLAVE mode> ③ Peripherals search Peripherals search is possible only in Master mode. Enter the command AT+BTINQ and Device Class 0x1F00(SPP) device peripheral will appear. ④ Connecting devices (pairing) Enter the command AT+BTINQ to search for peripherals and the MAC address will display (12-digit hexadecimal) then it can connect. For example MAC address abc2-ff-123458appears on the terminal; enter the command ATDabc2ff123458 and pairing will be attempted with the device with said device. Look for the device pin code (default is 0000.). ⑤ Pin Code change AT+BTKEY= 4-digit pin code The illustration below shows how to change the pairing pin code. Simply enter the command AT+BTKEY (the = sign is unnecessary) ⑥ Current Device Class output This is possible when the BT-210 is in SPP(Serial Port Profile) mode( 0x1f00). ⑦ Bluetooth device name change Enter AT+BTNAME = to change name ⑧ Device Under Test mode (DUT) Bluetooth device performance can be measured in DUT mode. Enter the command AT+BTDUT; the current mode will toggle. Enter ATZ and the mode during toggle will be selected after a reset (note: this can only be done under SLAVE mode only). To exit DUT mode enter the command AT+BTDUT and DUT mode is disabled will display; enter ATZ to reset. Communications mode Besides pairing with the BT-210 1:1 communications is also reliable. [ 1:1 communications ] • Pair 2 Bluetooth devices (1 being the BT-210); one in MASTER mode (the other device) and the other in SLAVE mode (BT-210). • When powered on the LED will blink; after successful pairing the LED will remain constantly on.

Operation Description 1) General Description It supports Bluetooth v2.1+EDR Specification radio transmissio n without the need for an external Power amplifier. Fully integrated synthesizer with out external VCO varacter diode,resonator or loop filter. It has designed for use in v oice application such as hands-free kits. It has designed with low power consumpt ion and most of can be controlled by microprocessor. 2) Radio Architecture (1) Transmitter Architecture -The Transmitter uses a conventional IQ modulator The Baseband Bluetooth signal is generated digitally and modulated in accordance with GFSK&π/4 DQPSK&8DPSK modulation scheme employed in Bluetooth. -The baseband signal is up-converted in the in-phase and quadrature (IQ) modulator to 2.4GHz. An RF amplifier then boosts the signal level and drivers differential RF_A and RF_B. -A conventional PLL synthesizer provides the local oscillator drive to the IQ modulator. The synthesizer produces signals at around 1.2GHz, which are then doubled to 2.4GHz. The 2.4GHz signal passes through a 90° phase splitter to provide the IQ driver to the modulator. The loop filter components for the synthesizer are internal to the chip. (2) Receiver Architecture -The receiver features a near-zero Intermediate Frequency (IF) architecture that allows the channel filters to be integrated on to the die. -A receiver of a double conversion design, which uses the same synthesizer as the transmitter. The RF switch enables the use of inputs from either the differential or signal-ended receive ports. The differential ports are the same RF_A and RF_B ports utilized by the transmitter. Single-ended inputs used the RF_IN port. -Both differential and single-ended inputs are amplified by a low noise amplifier (LNA) and passed to an IQ demodulator. This signal is amplified and filtered. The signal is limited, sampled and then digitally demodulated. The Analogue to Digital Converter (ADC) is used to implement fast Automatic Gain Control (AGC). The ADC samples the Received Signal Strength Indicator (RSSI) voltage on a slot-by-slot basis. The front-end LNA gain is changed according to the measured RSSI value, keeping the first mixer input signal within a limited range.

General Information 2.1 Product Description The ROBOTIS Model BT-210 (referred to as the EUT in this report) is used to remote Toys controller which has a function of Bluetooth. The product specification described herein was obtained from product data sheet or user’s manual. Equipment Name Bluetooth Operating Frequency 2402 MHz ~ 2480 MHz RF Output Power 8.00 dBm Number of Channel 79 Channels Mode of Operation Duplex Modulation Type GFSK Antenna Type / Gain SMD Chip Antenna / 2.69 dBi (Max) List of Each OSC. Or Crystal. Freq. 26 MHz Rated Supply Voltage DC 3.3 V 3. EUT MODIFICATION - NONE. 4. Information about the FHSS characteristics 4.1 Pseudorandom frequency hopping sequence The channel is represented by a pseudo-random hopping sequence hopping through the 79 RF Channels. The hopping sequence is unique for the piconet and is determined by the Bluetooth device address of the master; the phase in the hopping sequence is determined by the Bluetooth clock of the master. The channel is divided into time slots where each slot corresponds to an RF hop frequency. Consecutive hops correspond to different RF hop frequencies. The nominal hop rate is 1600 hops/s. Example of a 79 hopping sequence in data mode: 40, 21, 44, 23, 42, 53, 46, 55, 48, 33, 52, 35, 50, 65, 54... 4.2 Equal Hopping Frequency Use All Bluetooth units participating in the piconet are time and hop-synchronized to the channel. KTI13EF04001 FCC ID: SOD-BT-210 Korea Technology Institute Co., Ltd. Page 5 of 34 4.3 System Receiver Input Bandwidth The input bandwidth of the receiver is 1 MHz. In every connection one Bluetooth device is the master and the other one is slave. The aster determines the hopping sequence. The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection (e.g. single multisport (packet) is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packet has no influence on the hopping sequence.. The hopping sequence generated by the master of the connection will be followed in any case. That means, a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence. 4.4 Equipment Description 15.247(g): In accordance w…
