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.

BIT ERR1
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
section.
