Functional Description
The ROK 101 008 is a complete Bluetooth module that has been specified and designed according to the Bluetooth System v1.0B . Its implementation is based on a high-performance integrated radio transceiver (PBA 313 01/2) working with a baseband controller, a flash memory and surrounding secondary components. Block Diagram ROK 101 008 has five major operational blocks. Figure 7 illustrates the interaction of the various blocks. The functionality of each block is as follows: 1. Radio functionality is achieved by using the Bluetooth Radio, PBA 313 01/ 2. Six operational blocks are shown for the radio section and their operation is as follows: 1a) VCO-tank is a part of the phase locked loop. The modulation is performed directly on the VCO. To ensure high performance the VCO-tank is laser trimmed. 1b) Loop filter, filters the tuning voltage of the VCO-tank. 1c) RX-balun handles transformation from unbalanced to balanced transmission. 1d) TX-balun handles biasing of the output amplifier stage and transformation from balanced to unbalanced transmission. 1e) Antenna switch directs the power either from the antenna filter to the receive ports or from the ASIC output ports to the antenna filter. 1f) Antenna filter band-pass filters the radio signal.
2.
The baseband controller is an ARM7-Thumb based chip that controls the operation of the radio transceiver via the UART interface. Additionally, the baseband controller has a PCM Voice and I2C interface. The baseband controller ROP 101 1112/C is used. A Flash memory is used together with the baseband controller. Please, refer also to the Firmware section. The voltage regulation block regulates and filters the supply voltage. VCC is typically 3.3V and two regulated voltages are produced. An internal clock is mounted on the module. The clock frequency is 13MHz and is generated from a crystal oscillator that guarantees a timing accuracy within 20ppm.

Bluetooth Module stack
The Host Controller Interface (HCI) handles the communication by the transport layer through the UART interface with the host, see figure 8. The Baseband and radio provides a secure and reliable radio link for higher layers. The following sections describe the Bluetooth module stack in more detail. It is implemented in accordance with and complies with the Specification of the Bluetooth System v1.0B . Bluetooth Radio Interface The Bluetooth module is a class 2 device with 4dBm maximum output power with no power control needed. Nominal range of the module with a typical antenna is up to a range of 10 m (at 0 dBm). It is compliant with FCC and ETSI regulations in the ISM band.

Baseband By default the first unit setting up a connection is the master of the point to point link. The master transmits in the even timeslots and the slave transmits in the odd timeslots. For full duplex transmission, a Time-Division Duplex (TDD) scheme is used. Packets are sent over the air in timeslots, with a nominal length of 625 s. A packet can be extended to a maximum of 5 timeslots (DM5 and DH5 packets) and is then sent by using the same RF channel for the entire packet. Two types of connections are provided - Asynchronous Connectionless Link (ACL) for data and the Synchronous Connection Oriented Link (SCO) for voice. Only two 64kb/s voice channel are supported, HV1 and HV3. Furthermore, there are also packages used for link control purposes. A variety of different packet types with error correction schemes and data rates can be used over the air interface. Also asymmetric communication is available for high speed communication in one direction. The Baseband provides the link-setup and control routines for the layers above. Furthermore, the Baseband also provides Bluetooth security like encryption, authentication and key management. Please refer to the Specification of the Bluetooth System v1.0B part B for in-depth information regarding the Baseband.
Firmware (FW)
The module includes firmware for the host controller interface, HCI, and the link manager, LM. The FW resides in the Flash and is available in object code format. Link Manager (LM) The Link Manager in each Bluetooth module can communicate with another Link Manager by using the Link Manager Protocol (LMP) which is a peer to peer protocol. The LMP messages have the highest priority and are used for link-setup, security, control and power saving modes. The receiving Link Manager filter-out the message and does not need to acknowledge the message to the transmitting LM due to the reliable link provided by the Baseband and radio. LM to LM communication can take place without actions taken by the host. Discovery of features at other Bluetooth enabled devices nearby can be found and saved for later use by the host. Please refer to the Specification of the Bluetooth System v1.0B part C for in-depth information regarding the LMP. Host Control Interface (HCI) The HCI provides a uniform command I/F to the Baseband and Link Manager and also to HW status registers. There are three different types of HCI packets: * * HCI command packets - from host to Bluetooth module HCI. HCI event packets - from Bluetooth module HCI to host. HCI data packets - going both ways.

at a pre-specified profile, the capabilities of such a profile is necessary to adjust to - see Specification of the Bluetooth System v1.0B Profiles. The interface for communicating with the Bluetooth module is achieved with the HCI UART Transport Layer on top of HCI, the module will communicate with a host through the UART I/F. The PCM I/F is also available for communicating voice. Please refer to the Specification of the Bluetooth System v1.0B part H:1-4 for in-depth information regarding the HCI and different transport layers I2C Interface A master I2C I/F is available on the module. The control of the I2C pins are performed by Ericsson specific HCI commands available in the FW implementation - see Appendix C. Antenna The ANT pin should be connected to a 50W-antenna interface, thereby supporting the best signal strength performance. Ericsson Microelectronics can recommend application specific antennas - see Appendix C. RESET# The assignment of the RESET# input is to generate a reset signal to the complete Bluetooth module. During power-up the reset signal is set `low' automatically so that power supply glitches are avoided. Therefore no reset input should be required after power-up.
Module HW Interfaces
UART Interface The UART implemented on the module is an industry standard 16C450 and supports the following baud rates: 300, 600, 900, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400 and 460800 bits/s. 128 byte FIFOs are associated with the UART. Four signals will be provided for the UART interface. TxD & RxD are used for data flow, and RTS & CTS is used for flow control. Please refer to the Specification of the Bluetooth System v1.0B part H:4 regarding the HCI and UART transport layers. PCM Voice Interface The standard PCM interface has a sample rate of 8 kHz (PCM_SYNC). The PCM clock is variable between 128 kHz and 2.0 MHz in the PCM slave mode. The PCM data can be linear PCM (13-16bit), -Law (8bit) or A-Law (8bit). The PCM I/F can be either master or slave - providing or receiving the PCM_SYNC. Redirection of PCM_OUT and PCM_IN can be accomplished as well. Over the air the encoding is programmable to be, CVSD and A-Law or -Law.
Power-up Sequence
There is no need for a power up sequence if VCC, ON and VCC_IO are tied together. A power up sequence, if used, shall be applied accordingly: Connection of the supply rails, GND and then VCC; then the ON signal should be applied in order to initiate the internal regulators; and finally, the VCC_IO supply rail can be activated. The power-down sequence is similar to the power-up procedure but in the reverse format. Therefore, the disconnection of the signals shall be as follows: VCC_IO, ON,VCC and finally GND. Power There are three inputs to the Voltage Management section (VCC, VCC_IO, ON). VCC is the supply voltage that is typically 3.3V.

A separate power supply rail (VCC_IO) is provided for the I/ O ports, UART and PCM. VCC_IO can either be connected to VCC or to a dedicated supply rail, which is the same as the logical interface of the host. Shielding / EMC Requirements The module has its own RF shielding and is approved according to the standards by FCC and ETSI. If the approval number is not visible on the outside when the module is utilized in the final product, an exterior label must state that there is a transmitter module inside the product. Ground Ground should be distributed with very low impedance as a ground plane. Connect all GND pins to the ground plane.

Assembly Guidelines
Solder Paste The ROK 101 008 module is made for surface mounting and the SSP connection pads have been formed after printing eutectic Tin/Lead solder paste. The solder paste to use is not critical as long as this is a normal eutectic solder paste. A preferred solder paste height is 150m. Soldering Profile It must be noted that the module should not be allowed to be hanging upside down in the re-flow operation. This means that the module has to be assembled on the side of the PCB that is soldered last. The re-flow process should be a regular surface mount soldering profile (full convection strongly preferred); the ramp-up should not be higher than 2oC/s and with a peak temperature of 210-235oC during 20-60 seconds. Pad Size It is recommended that the pads on the PCB should have a diameter of 0.7-0.9 mm. The surface finish on the PCB pads should be Nickel/Gold or a flat Tin/Lead surface or OSP (Organic Surface Protection). Placement The placement machine should be able to recognize odd BGA combinations (all ball recognition preferred) and be able to pick the component asymmetrical. The module contains a flat pick-area of 10mm diameter minimum. The weight of the module is typically 2.8gr. Storage Keep the component in its dry pack when not yet using the reel. After removal from the dry pack ensure that the modules are soldered onto the PCB within 48 hours.
Packaging
All devices will be delivered in a package protecting them from electrostatic discharges and mechanical shock. The package will be marked with the following information: a) b) c) d) e) f) Delivery address. Purchase order-number Type of goods and component designation. Ericsson's name and logotype.

APPENDIX A
Getting Started
The ROK 101 008 Bluetooth module is easy to use when designing a Bluetooth application. However, there is a need for know-how in the Bluetooth System specification v1.0B as well as the Profile specification v1.0B when designing and end-customer product. The list below show some parts that would make designing convenient. * Bluetooth module * Know-how in Bluetooth specification regarding HCI commands * Test board with UART/PCM or USB I/F * Visual C++ for PC SW design * Preferably HCIdriver, L2CAP, RFCOMM and SDP from Ericsson All information needed, regarding how to drive the HCI over UART is specified in part H4 of the Bluetooth System v1.1 further more part H1 and also Appendix IX with message charts is relevant. Below follow an example of how to set up an ACL link between to Bluetooth modules by using the UART I/F and also a schematic of how to interface the module and control it by a host, normally a PC or microcontroller.
Setting up a Bluetooth point-to-point connection
The Host Controller Interface (HCI) in the module is a command I/F. The host presents commands to the HCI and receives events back from the HCI of the module. The module Link Manager provides link set up capability to the HCI. * Host_B Bluetooth module is set in paging scan mode - listening for a Bluetooth device asking for a new connection * Host_A Bluetooth module is set in paging mode asking for a connection to Host_B This is accomplished by first setting up the connection between the Host and the module and thereafter creating the connection between the modules using HCI commands.
Host set-up via UART:
There are 4 different types of HCI-packets accepted on the UART I/F.
HCI packet type HCI command packet HCI ACL data packet HCI SCO data packet HCI event packet HCI packet indicator 0x01 0x02 0x03 0x04
Principle schematic for UART interconnect
The inter-connection to the level-shifter when designing a test-board could be according to the schematic below. (Figure A1.) The Bluetooth module can be connected as a DCE/DTE and a modem/nullmodem cable could therefor be used in-between the test-board and the PC.
Table A1. HCI packets The HCI packet indicator shall be sent immediately before the HCI packet. When the entire HCI packet has been received a new indicator should be expected. The default speed setting is 57.6 kb/s and can be changed by sending a specified bit stream to the I/F - see Appendix C on how to change the speed setting of the UART. When the speed set-up for the UART is made for both Host_ A & B, the Command Packets can be sent and Event Packets received by the hosts. See HCI over UART in part H:4 of the Bluetooth System v1.0B for detailed information regarding parameters and protocol. Soft Reset First HCI command packet to send should be the RESET packet. A Command_Complete_Event with a status parameter should be returned to the host.

Buffer information Buffer information should be exchanged between the module and respective host by using HCI commands. * Read_Buffer_Size: Providing the host with information on buffer size for ACL and SCO data packets for the module returned with a Command_Complete_Event packet. The host shall use this information for controlling the transmission * Host_Buffer_Size: Providing the module with information on buffer size for ACL and SCO packets to the host. It is the host that manages the data buffers of the Host Controller on the module. Timers It could be necessary to set important timers used by the module for time out handling. The timers are all set by writing to registers using HCI commands. The default values can be checked in Specification of the Bluetooth System v1.0B part H:1 or by using Read_xxx_xxx commands. Bluetooth Address The hosts, using the HCI command Read_BD_ADDR will find the Bluetooth address of the module by the Command_Complete_Event with the BD_ADDR as a parameter. By Remote_Name_Request, the BD_ADDR of the remote module can also be found. Inquiry The HCI command Inquiry with the parameters LAP, Inquiry_Length, and Num_Responses can also be used for collecting BD_ADDR of remote Bluetooth units. Furthermore the setting of authentication and encryption should be disabled (default) by using the: * Write_Authentication_Enable * Write_Encryption_Mode The basic settings for getting into scan mode could be according to the below suggested script list. * Read Buffer Size * Set Event Filter * Write Scan Enable: (Scan Enable: 0x03) * Write Voice Setting: (Voice Channel Setting: 0x0060) * Write Authentication Enable: (Authentication Enable: 0x00) * Set Event Filter: (Connection Setup Filter: Connections from All Devices, Auto Accept: 0x02) * Write Connection Accept Timeout: (Connection Accept Timeout: 0x2000) * Write Page Timeout: (Page Timeout: 0x3000) Page mode The Create_Connection command is used to set-up a link to another Bluetooth device.

Table A3. HCI Create Connection OCF code Create_Connection: BD_ADDR: 0xYYYYYYYYYYYY, Packet Type: 0x0008, Page Scan Repetition Mode: 0x01, Page Scan Mode: 0x00, Clock Offset: 0x0000 Allow_Role_Switch: 0x00 This command will cause the Link Manager to try to create a connection to the Bluetooth module with the appropriate BD_ADDR. The local Bluetooth module (Host_A) starts the paging process to set up a link to the page-scanning remote device (Host_B). By LMP the negotiation between the two Bluetooth modules Link Managers (LM) the link set-up can be completed.
Creating a Point-to-point connection

ACL link up and running Host_A is the master of the point-to-point piconet and Host_B is slave. The unit starting the paging process is by definition the master. The link set-up is completed when the event Connection_Complete_Event is returned to both Host_A and Host_B with the connection handle as one of the parameters and the status parameter 0x00 (success). When Bluetooth link is up and running the HCI data packets can be sent from host to host. The host must take care of generating the packages going from Host to Host Controller in the module over the UART I/F, in the same way the Host must arrange the packages received from the Host Controller. Both sides need information on what kind of data is received, to be able to interpret the bit flow correctly. For extensive information on setting up a Bluetooth link please refer to Bluetooth System v1.0B Appendix IX Message Sequence Charts Adding an SCO link When creating a voice connection using the PCM I/F, an ACL link must be up and running between the two devices, an SCO link can thereafter be added. The control of the PCM I/F (FS, PCM_IN/OUT and PCM_CLK) is handled by Ericsson specific HCI command - see Appendix C.

Driving SW
HCI- API The Bluetooth module includes all HCI command capabilities according to Bluetooth System v1.0B. Furthermore, there is some Ericsson specific commands available for accessing HW registers and HW control - see Appendix C. SW for driving the module should be developed for the HCI interface. There is source code SW available with Ericsson Bluetooth Developers Kit (EBDK), see Appendix B, which can be used for driving the module. This SW comes with the EBDK and has an HCI-API for application development on the HCI I/F. Higher layer-API Software (HCIdriver, L2CAP, RFCOMM and SDP) are available in a generic, source code format, i.e. to be adapted to various operating systems. * HCIdriver - implements the HCI command driver used by the host * L2CAP - handles protocol multiplexing, segmentation and re-assembly of packets * RFCOMM - provides a serial port emulation over the L2CAP protocol * SDP - Service Discovery Protocol provides information on the services available on a Bluetooth device Additional SW for the application shall be developed for the actual application on top of the RFCOMM API. If the application is according to a SIG predefined profile, it should be implemented accordingly. New applications can be the driver of the specification of new profiles decided by the SIG - see Specification of the Bluetooth System v1.0B Profiles.

Development tools
Bluetooth Development Kit (EBDK) The easiest way of getting started is to use the Bluetooth Developers Kit. It provides all parts necessary for developing applications for the Bluetooth module. Available are: * PC plug&play * Demos using radio/baseband * Macro capability * C++ v5.0 Source code for use in applications * HCIdriver, L2CAP, SDP and RFCOMM for applications using UART communication * Pins for electrical measurements * Antennas Development can easily take place on the EBDK platform and thereafter the implementation of the full Bluetooth capability can be setup by developed SW/HW and the Bluetooth module. Software (HCIdriver, L2CAP, RFCOMM and SDP) will be available in source code for PC. * HCIdriver - implements the HCI command driver used by the host * L2CAP - handles protocol multiplexing, segmentation and re-assembly of packets * RFCOMM - provides a serial port emulation over the L2CAP protocol * SDP - Service Discovery Protocol provides information on the services available on a Bluetooth device Technical support is available from the EBDK distributor. Please contact Ericsson Microelectronics for ordering and information regarding the EBDK and regarding extra daughter board with ROK 101 008 as add-on to the EBDK. Bluetooth Starter Kit (EBSK) A very small convenient kit, which preferably is used in point-to-multipoint configuration designs, based on the Bluetooth module ROK 101 008.

Bluetooth Information
This part will be updated and new information will be added continuously. Radio Fast Frequency hopping (1600channel hop/s) with 79(23) channels available (2.402 to 2.480 GHz) and a symbol rate of 1Ms/s over the air exploits the maximum channel bandwidth in the unlicensed ISM band. To sustain a high transfer rate in busy radio environment, the frequency hopping together with advanced coding techniques maximizes the throughput. During Page and Inquiry the hopping frequency is risen to 3200 hops/s to enhance the time needed for connection set-up.
Modulation technique is a binary Gaussian Frequency Shift Keying GFSK, with a BT product of 0.5. The channel bandwidth is 1 MHz and the frequency deviation from the carrier frequency of the RF channel is between +/-140 to +/-175 kHz for representing a `1'/'0'. A rapid process is ongoing to harmonise Spanish, French and Japanese frequency ranges with the rest of the world. Data and parameter formats There are exceptions in the Bluetooth system for data and parameter formats - general rules below. * All values are in Binary and Hexadecimal little Endian formats * Negative values must use 2's complement format * Array parameter notation is parameterA[i], parameterB[i],... * All parameter values are sent/received in little Endian format. The least significant byte is sent first - unless noted otherwise.

HCI Opcodes The Opcodes have been changed during the ongoing standardisation work. Below is the description on how to send opcodes to the module. Below is the general HCI command packet format depicted as well as a byte order description. UART speed setting The baud rate is changed with an Ericsson specific HCI command. HCI_Ericsson_Set_Uart_Baud_Rate The command has one parameter, baud rate - one byte long according to the table below . The op-code for the command is 0xfc09 - the last figure is due to a possible change. Sending the command should be performed accordingly: 09 fc 01 yz , where yz is the chosen baud rate from the table. The op-code is sent in reverse byte order. 01 is the parameter length, in this case one byte. Remember to add the HCI packet indicator. Observe - When changing the baud rate for the module the host also has to change the baud rate. Observe - Removing power to the module the baud rate will be reset to 57.6 kbps. Observe -Two zeros are not printed in the beginning of the binary parameters below. The length of the parameter is 1 byte. Ericsson specific HCI commands By using the Ericsson specific HCI command there are a number of features available for the application design. Contact Ericsson Microelectronics for a command reference list. Antennas Antenna design is not specified and standardised in the Bluetooth System v1.0B. Many different types of antennas can and will be used. Application specific antennas suitable for production are expected to be a new market for antenna designs. Ericsson Microelectronics have antennas for the EBDK and other development kits. Contact Ericsson Microelectronics for information on antennas.
