Version 1.0 Samsung Electronics page 2 of 6 3. Operational Description BTM730B BT Module is RF communication controller which is equipped with AIO PC for the users who use wireless devices. A number of channels are 79 which are based on IEEE 802.15.1/1a and frequency range is 2402MHz ~ 2480MHz. Each channel has a bandwidth of 1 MHz. - Transmitter Baseband processor uses FFHS (Frequency Hopping Spread Spectrum) scheme to avoid interference from other signals by hopping to a new frequency after transmitting or receiving a packet. BTM740B BT Module provides 1Mbps, 2Mbps (EDR), 3Mbps (EDR) data rate and 2FSK/DQPSK/8DPSK modulation. Tx signal is modulated as Tx IQ by DAC (Digital-Analog Convertor) inside of baseband IC then it is transmitted through internal PA (Power Amplifier). - Receiver Transceiver IC is insulated by Low Noise Amplifier (LNA) to avoid undesirable noise interferences. RF signal is converted and demodulated as RX IQ by through intermediate frequency and RF filter then it is input to the processing unit. - Power Class BTM730B BT Module operate as BT Power Class 1 of IEEE 802.15.1/1a Standard. - Interface BTM730B BT Module supports standard UART interface and UART setting values are as Table.1. Table.1 UART Setting
