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. l B u e C o r e T M 0 1 BlueTest Example Display Introduction 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. The tests fall into six categories:

g Simple RF tests; used for PCB de-bug and optimisation g Quantitative tests for transmit and receive; used to establish the performance of the Bluetooth device. g Loopback test modes; used for qualification and regulatory testing g Configuration commands to set parameters for other tests g Built-in self-test routines g Miscellaneous test routines Further details about commands, parameters and packet types are included in the appendices following the tests. 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 CSRs Casira development kit. bc01-an-047b This material is subject to CSRs non-disclosure agreement.

A check is made that the data read back is the same (up to usual codec transformations) as that written. The LOOP BACK consists of 512 bytes of random data. The PCM port mode is selectable as PCM Mode (pcm_mode), which is the same as for PCM LB

(radiotest_pcm_loop_back) The external LOOP BACK may be a simple wire. Related Test Spec Name None Note On the Casira under test, set CN8 jumper to Codec BYP and on header CN12 link pins 10 and 11. Test Arguments PCM Mode = 0 to 2 (default = 1) Return Data None Exit Click on Reset Chip.

(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. The tests concerned are:

g VCOTRIM g BUILD LUT g READ g LUT

(b) There is a race between command responses indicating that a test has started and the first data relating to that test. This does not affect the test results.

(c) It is not possible to rouse the chip from Deep Sleep except by powering down the chip and restarting. bc01-an-047b This material is subject to CSRs non-disclosure agreement.

Operation is subject to the two following 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. Changes or modifications to the transmitter not expressively approved by CSR could void the authority ability to operate the equipment. User Label Warning !

The transmitter is in compliance with the Part 15 FCC Rules. A label which demonstrates compliance with the FCC is located on the bottom of the laptop. The label contains the following information :-

Contains FCC ID:- PIW632500516610 This label ID is to be used only for Dell lap tops. The use of this transmitter outside Dell laptops is illegal. l B u e C o r e T M 0 1 Transmitter Warning !

Installers of the Bluetooth transmitter should note that the Bluetooth transmitter should not be co-located with any other transmitter, for example WLAN interfaces in the lap top. The distance between the Bluetooth transmitter and antennas of other radio equipment must be at least 20cm in distance away from each other. Any closer installations require additional certification filings to examine co-location issues. bc01-an-047b This material is subject to CSRs non-disclosure agreement.
