BlueTest Instruction Manual
BlueTest is a program that controls the
on-chip built-in-self-test (BIST) software for
RF testing. This document explains the
facilities offered by the BIST. BlueTest does
not execute any of these tests. It sends
commands to BlueCore01 and/or enables
the on-chip BIST, then reports any results.
Several tests include entries for Related Test
Spec Name. These refer to tests in the
Bluetooth Special Interest Group (SIG) Test
Specification for RF document, rev. 0.9r,
dated 31 January 2000.
The tests fall into six categories:
Simple RF tests; used for PCB de-bug
and optimisation
Quantitative tests for transmit and
receive; used to establish the
performance of the Bluetooth device.
Loopback test modes; used for
qualification and regulatory testing
Configuration commands to set
parameters for other tests
Built-in self-test routines
Miscellaneous test routines
Further details about commands,
parameters and packet types are included
in the appendices following the tests.
BlueTest Example Display
Running a Test
In a BlueTest dialog select the Standard
button to display the entire test. This applies
to all of the tests except for the BIT ERR1
and BIT ERR2 tests. Click on Bit Error to
display these results in a column format.
When running the tests, the results display in
a dialog box.
The default file name is logfile.txt. It is
located in the current directory in which the
program resides. Select Browse for File to
create your own file name and path (using
test examples provided).
To save test results to a file, tick Save to File .
Note: Some of these tests require two
Bluetooth modules to function correctly. The
PCM External Loopback test has notes
specifically for use with CSR’s Casira
development kit.

BlueCoreTM01
Title
Enables the receiver at a designated frequency (LO Freq) with a
choice of low or high side modulation (hi-side ) and with a designated
attenuation setting (RX Attenuation ).
Returns a set of reports to the host:
Summary
Number of data bits received (payload excluding FEC and CRC)
Number of data bits that were in error. Assumes PRBS9 data
starting with 1FF in each packet
Number of packets received
Number of packets expected, based on txrx_freq (default
12500)
Number of packets with header errors as reported by hardware
Number of packets with CRC errors
Number of packets with uncorrected errors (currently same as
CRC errors)
Number of sync timeouts. Note that until a transmission is
received a long timeout is used, so this does not reflect the
number of packets expected
Each report has two unint32 values. First is value since last report,
second is summed over the last bits_count (default =
1.6Mbits).
Reports are sent according to report_freq set (default = 1
second). The times between receive slots and report frequency can
be set, and the count reset. Refer to Configuration Commands

CFG UAP/LAP
Summary
Sets the UAP and LAP to be used in tests. BlueCore01 usually
uses its own Bluetooth Device address to determine the access
sync code, as if it is master of a piconet. The UAP and LAP are
the only parts used. This command allows a special UAP and LAP
to be used only in the test modes.

Known Software Issue(s) in BlueTest Version 1.4
(a) Pressing the Reset Chip button on the GUI while data is being transmitted sends a
hardware reset command to the chip and restarts the serial stack software.
Closing the GUI sends a hardware reset command to the chip.
If the link fails, the connection can only be recreated by manually resetting the chip
(power off/on) and by clicking on Reset Chip or closing down and restarting the GUI (both
of which will restart the serial stack software).
The above will not occur if no data is visibly scrolling in the window.

(b) There is a race between command responses indicating that a test has started and the

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
FCC Radiation Exposure Statement:
This device complies with FCC’s RF radiation exposure limits set forth for an
uncontrolled environment. To maintain compliance, this transmitter must not be co-located
or operating in conjunction with any other antenna or transmitter.
INSTRUCTIONS FOR OEM INTEGRATORS
This transmitter module is authorized to be used in other devices only by OEM
integrators. Further transmitter testing will not be required. However, the OEM integrator
is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions,
PC peripheral requirements, etc.)
The OEM integrator has to be aware not to provide information to the end user regarding
how to install or remove this RF module in the user manual of the end product.
