4.5 RF Interface
For This Module, the default mode for antenna is external antenna.
The user can connect a 50 ohm antenna directly to the RF port.
2402–2480 MHz Bluetooth 2.1; 1 Mbps to 3 Mbps over the air data rate.
TX output power of +8dBm.
Receiver to achieve maximum sensitivity -85dBm @ 0.1% BER.
4.6 Serial Interfaces
4.6.1 UART
FSC-BT956B provides one channels of Universal Asynchronous Receiver/Transmitters(UART)(Full-duplex asynchronous
communications). The UART Controller performs a serial-to-parallel conversion on data received from the peripheral
and a parallel-to-serial conversion on data transmitted from the CPU. Each UART Controller channel supports ten types
of interrupts.
This is a standard UART interface for communicating with other serial devices. The UART interface provides a simple
mechanism for communicating with other serial devices using the RS232 protocol.
When the module is connected to another digital device, UART_RX and UART_TX transfer data between the two
devices.
This module output is at 3.3V CMOS logic levels (tracks VCC). Level conversion must be added to interface with an
RS-232 level compliant interface.
