Enhanced coexistence data can be exchanged over GCI_SECI_IN and GCI_SECI_OUT a two-wire interface, one serial input (GCI_SECI_IN), and one serial output (GCI_SECI_OUT). The both pins are controlled by the configuration file that is stored in EEPROM from the host. It supports generic UART communication between WLAN and Bluetooth devices.
To conserve power, it is disabled when inactive.
It supports automatic resynchronization upon waking from sleep mode. It supports a baud rate of up to 4 Mbps. Error! Reference source not found. shows the 2-wire BT coexistence interface assignments.

USB Interface BT85x has a full-speed (12 Mbps) USB interface for communicating with other compatible digital devices. The USB interface on the BT85x acts as a USB peripheral, responding to requests from a master host controller. BT85x supports the Universal Serial Bus Specification (USB v2.0 Specification) and USB Battery Charging Specification, available from http://www.usb.org. For more information on how to integrate the USB interface on BT85xd, see Figure 15 located in the following section: USB Dongle Design Example Using BT850. The following USB interface features are supported:
Integrated detach resistor
USB Protocol, revision 2.0, full-speed compliant with LPM support (up to 12 Mbps)
Bluetooth HCI
HID, DFU, UHE (proprietary method to emulate an HID device at system boot)
USB termination when interface is not in use
8.3. PCM Interface Internal modules, certification, and non-specification compliant operation The BT850-Sx supports two independent PCM interfaces that share the pins with I2S interfaces. The PCM interface on the BT850-Sx can connect to linear PCM Codec devices in master or slave mode. In master mode, the BT850-Sx generates the PCM_CLK and PCM_SYNC signals; in slave mode, these signals are provided by another master on the PCM interface and are inputs to the BT850-Sx. The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI commands. 8.3.1. Slot Mapping The BT850-Sx supports up to three simultaneous full-duplex SCO or eSCO channels through the PCM interface. These three channels are time-multiplexed onto the single PCM interface by using a time-slotting scheme where the 8 kHz or 16 kHz audio sample interval is divided into as many as 16 slots. The number of slots is dependent on the selected interface rate of 128 kHz, 512 kHz, or 1024 kHz. The corresponding number of slots for these interface rate is 1, 2, 4, 8, and 16, respectively. Transmit and receive PCM data from an SCO channel is always mapped to the same slot. The PCM data output driver tristates its output on unused slots to allow other devices to share the same PCM interface signals. The data output driver tristates its output after the falling edge of the PCM clock during the last bit of the slot. 8.3.2. Frame Synchronization The BT850-Sx supports both short- and long-frame synchronization in both master and slave modes. In short-
frame synchronization mode, the frame synchronization signals an active-high pulse at the audio frame rate that is a single-bit period in width and is synchronized to the rising edge of the bit clock. The PCM slave looks for a high on the falling edge of the bit clock and expects the first bit of the first slot to start at the next rising edge of the clock. Figure 2 and Table 9 shows PCM Timing Diagram and Specifications for the master mode of short-frame. Embedded Wireless Solutions Support Center:

25 Unit MHz ns ns ns ns ns ns ns ns 8.3.3. Data Formatting The BT85-Sx0 may be configured to generate and accept several different data formats. For conventional narrowband speech mode, the BT850 uses 13 of the 16 bits in each PCM frame. The location and order of these 13 bits can be configured to support various data formats on the PCM interface. The remaining three bits are ignored on the input and may be filled with 0s, 1s, a sign bit, or a programmed value on the output. The default format is 13-bit 2s complement data, left justified, and clocked MSB first. 8.3.4. Wideband Speech Support When the host encodes Wideband Speech (WBS) packets in transparent mode, the encoded packets are transferred over the PCM bus for an eSCO voice connection. In this mode, the PCM bus is typically configured in master mode for a 4-kHz sync rate with 16-bit samples, resulting in a 64 Kbps bit rate. The BT850-Sx also supports slave transparent mode using a proprietary rate-matching scheme. In SBC-code mode, linear 16-bit data at 16 kHz (256 Kbps rate) is transferred over the PCM bus.

Multiplexed Bluetooth Over PCM Bluetooth supports multiple audio streams within the Bluetooth channel and both 16 kHz and 8 kHz streams can be multiplexed. This mode of operation is only supported when the Bluetooth host is the master. Figure 6 shows the operation of the multiplexed transport with three simultaneous SCO connections. To accommodate additional SCO channels, the transport clock speed is increased. To change between modes of operation, the transport must be halted and restarted in the new configuration. Figure 6: Functional multiples data diagram 8.3.6. Burst PCM Mode In this mode of operation, the PCM bus runs at a significantly higher rate of operation to allow the host to duty cycle its operation and save current. In this mode of operation, the PCM bus can operate at a rate of up to 24 MHz. This mode of operation is initiated with an HCI command from the host.

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 BT85x Series Datasheet I2S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S SDO always stays as an output. The channel word length is 16 bits and the data is justified so that the MSB of the left-channel data is aligned with the MSB of the I2S bus, per the I2S specification. The MSB of each data word is transmitted one bit clock cycle after the I2S WS transition, synchronous with the falling edge of bit clock. Left-channel data is transmitted when I2S WS is low, and right-channel data is transmitted when I2S WS is high. Data bits sent by the BT850 are synchronized with the falling edge of I2S_SCK and should be sampled by the receiver on the rising edge of I2S_SSCK. The clock rate in master mode is either of the following:
48 kHz x 32 bits per frame = 1.536 MHz 48 kHz x 50 bits per frame = 2.400 MHz The master clock is generated from the input reference clock using a N/M clock divider. In the slave mode, any clock rate is supported to a maximum of 3.072 MHz. 8.4.1. I2S Timing Timing values specified in Table 15 are relative to high and low threshold levels.

MUST locate the BT850 module close to the edge of PCB.
Use solid GND plane on inner layer (for best EMC and RF performance).
Place GND vias close to module GND pads as possible
Route traces to avoid noise being picked up on VCC supply.
Antenna Keep-out area:
Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. Keep all mounting hardware and metal clear of the area to allow proper antenna radiation. For best antenna performance, place the BT850 module on the edge of the host PCB, preferably in the corner with the antenna facing the corner. A different host PCB thickness dielectric will have small effect on antenna. Figure 14: Recommend antenna keep-out area (in blue) used on the BT850 11.1.1. Antenna Keep-out and Proximity to Metal or Plastic Checklist (for metal/plastic enclosure):
Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right.
Metal close to the BT850 chip monopole antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of degradation is entirely system-dependent which means some testing by customers is required (in their host application).
Any metal closer than 20 mm starts to significantly degrade performance (S11, gain, radiation efficiency).
It is best that the customer tests the range with mock-up (or actual prototype) of the product to assess effects of enclosure height (and material, whether metal or plastic). Embedded Wireless Solutions Support Center:

Enhanced coexistence data can be exchanged over GCI_SECI_IN and GCI_SECI_OUT a two-wire interface, one serial input (GCI_SECI_IN), and one serial output (GCI_SECI_OUT). The both pins are controlled by the configuration file that is stored in EEPROM from the host. It supports generic UART communication between WLAN and Bluetooth devices.
To conserve power, it is disabled when inactive.
It supports automatic resynchronization upon waking from sleep mode. It supports a baud rate of up to 4 Mbps.

The UART is a standard four-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates from 38400 bps to 4.0 Mbps. The interface features an automatic baud rate detection capability that returns a baud rate selection. Alternatively, the baud rate may be selected through a vendor-specific UART HCI command. UART has a 1040-byte receive FIFO and 1040-byte transmits FIFO to support EDR. Access to the FIFO is conducted through the AHB interface through either DMA or the CPU. The UART supports the Bluetooth 4.2 UART HCI specification: H4, and a custom Extended H4. The default baud rate is 115.2 Kbaud. The BT860 UART can perform XON/XOFF flow control and includes hardware support for Serial Line Input Protocol (SLIP). It can also perform wake-on activity. For the BT860 is supported BT to wake-up Host. Normally, the UART baud rate is set by a configuration record downloaded after device reset, or by automatic baud rate detection, and the host does not need to adjust the baud rate. Support for changing the baud rate during normal HCI UART operation is included through a vendor-specific command that allows the host to adjust the contents of the baud rate registers. The BT860 UARTs operate correctly with the host UART if the combined baud rate error of the two devices is within 2%. Table 9: Example of common baud rates Desired Rate Actual Rate Error (%) 4000000 3000000 2000000 1500000 921600 460800 230400 115200 57600 38400 4000000 3000000 2000000 1500000 923077 461538 230796 115385 57692 38400 0.00 0.00 0.00 0.00 0.16 0.16 0.17 0.16 0.16 0.00 8.2.1. Simultaneous UART Transport and Bridging The BT860 supports UART or USB interfaces that can function as the host controller interface (HCI). Typically, a customer application would choose one of the two interfaces and the other would be idle. The BT860 allows the UART transport to operate simultaneously with the USB. To operate this way, the assumption is that the USB would function as the primary host transport, while the UART would function as a secondary communication channel that can operate at the same time. This can enable the following applications -
Bridging primary HCI transport traffic to another device via the UART
Generic communication to an external device for a vendor-supported application via the UART Table 10 and Figure 2 shows UART timing of specifications. Embedded Wireless Solutions Support Center:

1.50 0.67 1.33 Bit periods Bit periods Bit periods Figure 2: UART timing 8.3. PCM Interface The BT860 supports two independent PCM interfaces that share the pins with I2S interfaces. The PCM interface on the BT860 can connect to linear PCM Codec devices in master or slave mode. In master mode, the BT860 generates the PCM_CLK and PCM_SYNC signals, and in slave mode, these signals are provided by another master on the PCM interface and are inputs to the BT860. The configuration of the PCM interface may be adjusted by the host using vendor-specific HCI commands. 8.3.1. Slot Mapping The BT860 supports up to three simultaneous full-duplex SCO or eSCO channels through the PCM interface. These three channels are time-multiplexed onto the single PCM interface by using a time-slotting scheme where the 8 kHz or 16 kHz audio sample interval is divided into as many as 16 slots. The number of slots is dependent on the selected interface rate of 128 kHz, 512 kHz, or 1024 kHz. The corresponding number of slots for these interface rate is 1, 2, 4, 8 and 16, respectively. Transmit and receive PCM data from an SCO channel is always mapped to the same slot. The PCM data output driver tristates its output on unused slots to allow other devices to share the same PCM interface signals. The data output driver tristates its output after the falling edge of the PCM clock during the last bit of the slot. Embedded Wireless Solutions Support Center:

Frame Synchronization The BT860 supports both short- and long-frame synchronization in both master and slave modes. In short-frame synchronization mode, the frame synchronization signal uses an active-high pulse at the audio frame rate that is a single-bit period in width and is synchronized to the rising edge of the bit clock. The PCM slave looks for a high on the falling edge of the bit clock and expects the first bit of the first slot to start at the next rising edge of the clock.

The remaining three bits are ignored on the input and may be filled with 0s, 1s, a sign bit, or a programmed value on the output. The default format is 13-bit 2s complement data, left justified, and clocked MSB first. Embedded Wireless Solutions Support Center:

Wideband Speech Support When the host encodes Wideband Speech (WBS) packets in transparent mode, the encoded packets are transferred over the PCM bus for an eSCO voice connection. In this mode, the PCM bus is typically configured in master mode for a 4 kHz sync rate with 16-bit samples, resulting in a 64 Kbps bit rate. The BT860 also supports slave transparent mode using a proprietary rate-matching scheme. In SBC-code mode, linear 16-bit data at 16 kHz (256Kbps rate) is transferred over the PCM bus. 8.3.5. Multiplexed Bluetooth Over PCM Bluetooth supports multiple audio streams within the Bluetooth channel and both 16 kHz and 8 kHz streams can be multiplexed. This mode of operation is only supported when the Bluetooth host is the master. Figure7 shows the operation of the multiplexed transport with three simultaneous SCO connections. To accommodate additional SCO channels, the transport clock speed is increased. To change between modes of operation, the transport must be halted and restarted in the new configuration. Figure 7: Functional Multiples Data diagram 8.3.6. Burst PCM Mode In this mode of operation, the PCM bus runs at a significantly higher rate of operation to allow the host to duty cycle its operation and save current. In this mode of operation, the PCM bus can operate at a rate of up to 24 MHz. This mode of operation is initiated with an HCI command from the host. Figure 8 and Table 15 shows PCM Burst mode timing diagram and specifications for the receive-only mode of short-frame sync. Embedded Wireless Solutions Support Center:

Unit MHz ns ns ns ns ns ns I2S Interface 8.4. The BT860 supports two independent I2S digital audio ports. The I2S interface supports both master and slave modes. The I2S signals are:
I2S clock: I2S SCK I2S Word Select: I2S WS I2S Data Out: I2S SDO I2S Data In: I2S SDI I2S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S SDO always stays as an output. The channel word length is 16 bits and the data is justified so that the MSB of the left-channel data is aligned with the MSB of the I2S bus, per the I2S specification. The MSB of each data word is transmitted one bit clock cycle after the I2S WS transition, synchronous with the falling edge of bit clock. Left-channel data is transmitted when I2S WS is low, and right-channel data is transmitted when I2S WS is high. Data bits sent by the BT860 are synchronized with the falling edge of I2S_SCK and should be sampled by the receiver on the rising edge of I2S_SSCK. The clock rate in master mode is either of the following:
48 kHz x 32 bits per frame = 1.536 MHz 48 kHz x 50 bits per frame = 2.400 MHz The master clock is generated from the input reference clock using a N/M clock divider. In the slave mode, any clock rate is supported to a maximum of 3.072 MHz. Embedded Wireless Solutions Support Center:

MUST locate the BT860 module close to the edge of PCB.
Use solid GND plane on inner layer (for best EMC and RF performance).
Place GND vias close to module GND pads as possible
Route traces to avoid noise being picked up on VCC supply.
Antenna Keep-out area:
Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. Keep all mounting hardware and metal clear of the area to allow proper antenna radiation. For best antenna performance, place the BT860 module on the edge of the host PCB, preferably in the corner with the antenna facing the corner. A different host PCB thickness dielectric will have small effect on antenna. Figure 15: Recommend Antenna keep-out area (in Blue) used on the BT860 11.1.1. Antenna Keep-out and Proximity to Metal or Plastic Checklist (for metal /plastic enclosure):
Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right.
Metal close to the BT860 chip monopole antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of degradation is entirely system dependent which means some testing by customers is required (in their host application).
Any metal closer than 20 mm starts to significantly degrade performance (S11, gain, radiation efficiency).
It is best that the customer tests the range with mock-up (or actual prototype) of the product to assess effects of enclosure height (and material whether metal or plastic). Embedded Wireless Solutions Support Center:
