When BTM800 is connected to another digital device, UART_RX and UART_TX transfer data between the 2 devices. UART configuration parameters, e.g. baud rate and data format, are set using BTM800 firmware. When selected in firmware PIO[0] is assigned to a UART_TX output and PIO[1] is assigned to a UART_RX input。 Note: To communicate with the UART at its maximum data rate using a standard PC, the PC requires an accelerated serial port adapter card. shows the possible UART settings for the BTM800 as below : Parameter Possible Values 1200 baud (≤2%Error) Minimum Baud rate 9600 baud (≤1%Error) Maximum 2Mbaud (≤1%Error) Parity None, Odd or Even Number of stop bits 1 or 2 The maximum baud rate is 2400 baud during deep sleep. Master I²C Interface SPI Master Interface The SPI master memory interface in the BTM800 is overlaid on the I²C interface and uses a further 3 PIOs for the extra pins： SPI master Interface Pin Flash_VDD PIO[2] SF_DIN PIO[3] SF_CS# PIO[4] SF_CLK I2C_SCL SF_DOUT I2C_SDA Note: If an application using BTM800 is designed to boot from SPI serial flash, it is possible for the firmware to map the I²C interface to alternative PIOs. Radio Characteristics Note: (a) Up to five exceptions are allowed in the Bluetooth V4.0+EDR specification on receiver part.. (b) Measured at F0 = 2441MHz. (c) Measured at f1-f2=5MHz. Measurement is performed in accordance with Bluetooth RF test RCV/CV/05.., i.e., wanted signal at -64dBm (d) Measured at unbalanced port of balun. Integrated in 100KHz bandwidth and normalised to 1Hz. actual figure is typically below -130dBm/Hz except for peaks -80dBm at 1600MHz, -80dBm in band at 2.4GHz and -80dBm at 3.2GHz Note: (1) Measurements methods are in accordance with the Bluetooth V4.0+EDR specification. (2) Up to five exceptions are allowed in the Bluetooth V4.0+EDR specification on receiver part. (3) Measured at F0 = 2405MHz, 2441MHz, 2477MHz.
