Preliminary

APPENDIX A

Getting Started

The ROK 101 007 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.

• Bluetooth module
• Know-how in Bluetooth specifica-

tion 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

The list above show some parts that
would make designing convenient.

All information needed, regarding
how to drive the HCI over UART is
specified in part H4 of the Bluetooth
System v1.0B 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 capa-
bility 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 con-

nection 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.
