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 unbal-

anced 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 trans-

ceiver via the UART interface. Additionally, the

baseband controller has a PCM Voice and I2C

interface. The baseband controller ROP 101 1112/C

is used.

3. A Flash memory is used together with the baseband

controller. Please, refer also to the Firmware section.

4. The voltage regulation block regulates and filters the

supply voltage. VCC is typically 3.3V and two regu-

lated voltages are produced.

5. 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 commu-

nication by the transport layer through the UART inter-

face 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.

Figure 9. Link manager

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 µs. 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, authen-

tication 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 commu-

nicate 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.

It is not necessary to make use of all different commands

and events for an application. If the application is aimed

ROK 101 008

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

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), µ-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 µ-Law.

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.

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 accord-

ingly: 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 150µm.

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.

Marking

Every module is marked with the following information on

the:

a) Component designation: “ROK 101 008”.

b) Ericsson’s name and logotype.

c) Manufacturing code (place, year, week) and batch

number.

d) CE logotype

e) Type approval RTA no. See manual

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.

Principle schematic for UART inter-

connect

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.

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 com-

mands.

Host set-up via UART:

There are 4 different types of HCI-packets accepted on

the UART I/F.

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.

HCI packet type HCI packet indicator

HCI command packet 0x01

HCI ACL data packet 0x02

HCI SCO data packet 0x03

HCI event packet 0x04

Table A1. HCI packets

ROK 101 008

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 control-

ling the transmission

• Host_Buffer_Size: Providing the module with informa-

tion 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.

Creating a Point-to-point connection

Page Scan mode

To set a Bluetooth module in the mode for being able to

connect to (Host_B), page scan mode, there are some

settings that should be performed.

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.

Data

Table A4. ACL data packet

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 develop-

ment 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 informa-

tion 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 applica-

tions

• 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 Microelec-

tronics 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.

Please contact Ericsson Microelectronics for

ordering and information regarding the

Ericsson Bluetooth Starter Kit.

APPENDIX C

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 connec-

tion 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 Microelec-

tronics for information on antennas.
