All Rights Reserved The BT860-Sx supports the proprietary Cypress Global Coexistence Interface (GCI) which is a 2-wire interface. The following key features are associated with the interface: - 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. Table 9 shows the two-wire BT coexistence interface assignments. _**Table 9: BT GCI Two-Wire Coexistence**_ |**Coexistence Signal Name**|**Signal Assignment**| |---|---| |BT_SECI_IN|GPIO_6| |BT_SECI_OUT|GPIO_7| The BT860-Sx has a single UART for Bluetooth. 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 5.0 UART HCI specification: H4, and a custom Extended H4. The default baud rate is 115.2 Kbaud. The BT860-Sx 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-Sx 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-Sx UART operates correctly with the host UART if the combined baud rate error of the two devices is within ±2%. _**Table 10: Example of common baud rates**_ |**Desired Rate**|**Actual Rate**|**Error (%)**| |---|---|---| |4000000|4000000|0.00| |3000000|3000000|0.00| |2000000|2000000|0.00| |1500000|1500000|0.00| |921600|923077|0.16| |460800|461538|0.16| |230400|230796|0.17| |115200|115385|0.16| |57600|57692|0.16| |38400|38400|0.00| https://connectivity.lairdtech.com/wireless10 **Americas** : +1-800-492-2320 modules/bluetooth-modules © Copyright 2019 Laird.

The PCM interface on the BT860-Sx 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. For additional information, refer to the DVK-BT86x User Guide available from the BT86x product page of the Laird website. ## 8.3.1. Slot Mapping The BT860-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 rates 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 BT860-Sx 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. https://connectivity.lairdtech.com/wirelessmodules/bluetooth-modules **Americas** : +1-800-492-2320 **Europe** : +44-1628-858-940 **Hong Kong** : +852 2923 0610 11 © Copyright 2019 Laird.

Data Formatting The BT860-Sx may be configured to generate and accept several different data formats. For conventional narrowband speech mode, the BT860-Sx 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 2’s 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 BT860-Sx 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. https://connectivity.lairdtech.com/wirelessmodules/bluetooth-modules **Americas** : +1-800-492-2320 **Europe** : +44-1628-858-940 **Hong Kong** : +852 2923 0610 14 © Copyright 2019 Laird. All Rights Reserved _**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.

All Rights Reserved The BT860-Sx supports two independent I[2] S digital audio ports. The I[2] S interface supports both master and slave modes. The I[2] S signals are: - I[2] S clock: I[2] S SCK - I[2] S Word Select: I[2] S WS - I[2] S Data Out: I[2] S SDO - I[2] S Data In: I[2] S SDI I[2] S SCK and I[2] S WS become outputs in master mode and inputs in slave mode, while I[2] S 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 I[2] S bus, per the I[2] S specification. The MSB of each data word is transmitted one bit clock cycle after the I[2] S WS transition, synchronous with the falling edge of bit clock. Left-channel data is transmitted when I[2] S WS is low, and right-channel data is transmitted when I[2] S 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. ## 8.4.1.

All Rights Reserved Checklist (for PCB): - **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-SA 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). https://connectivity.lairdtech.com/wirelessmodules/bluetooth-modules 22 **Americas** : +1-800-492-2320 © Copyright 2019 Laird.

All Rights Reserved ## 12.3. Reflow Parameters Laird surface mount modules are designed to be easily manufactured, including reflow soldering to a PCB. Ultimately it is the responsibility of the customer to choose the appropriate solder paste and to ensure oven temperatures during reflow meet the requirements of the solder paste. Laird’s surface mount modules conform to J-STD-020D1 standards for reflow temperatures. **Important** : During reflow, modules should not be above 260° and not for more than 30 seconds. In addition, we strongly recommend that you do not put the module through reflow more than once. Otherwise, it impacts the module’s soldering. _**Figure 19: Recommended reflow temperature**_ Temperatures should not exceed the minimums or maximums presented in Table 202. _**Table 202: Recommended maximum and minimum temperatures**_ |**Specification**|**Value**|**Unit**| |---|---|---| |Temperature Inc./Dec.

Application Note: Subsystem Combinations This application note covers the procedure for generating a new Declaration ID for a Subsystem combination on the Bluetooth SIG website. In the instance of subsystems, a member can combine two or more subsystems to create a complete Bluetooth End Product solution.

This is achieved by using the Listing interface on the Bluetooth SIG website. Table 24 shows the basic subsystem combination of a controller and host subsystem. The Controller provides the RF/BB/LM and HCI layers, with the Host providing L2CAP, SDP, GAP, RFCOMM/SPP and any other specific protocols and profiles existing in the Host subsystem listing. The design may also include a Profile Subsystem.

This can be done before starting the new qualification, either through invoicing or credit card payment. The fees for the Declaration ID will depend on your membership status, please refer to the following webpage: https://www.bluetooth.org/en-us/test-qualification/qualification-overview/fees For a detailed procedure of how to obtain a new Declaration ID for your design, please refer to the following SIG document: https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=283698&vId=317486 To start the listing, go to: https://www.bluetooth.org/tpg/QLI_SDoc.cfm. In step 1, select the option, **Reference a Qualified Design** and enter the Declaration IDs of each subsystem used in the End Product design. You can then select your pre-paid Declaration ID from the drop down menu or go to the Purchase Declaration ID page, (please note that unless the Declaration ID is pre-paid or purchased with a credit card, it will not be possible to proceed until the SIG invoice is paid. Once all the relevant sections of step 1 are finished, complete steps 2, 3, and 4 as described in the help document. Your new Design will be listed on the SIG website and you can print your Certificate and DoC.
