BlueTest Instruction Manual bc01-an-047b © Copyright CSR Ltd 2000 This material is subject to CSR’s non-disclosure agreement. Page 3 of 56 BlueCoreTM01 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 CSR’s Casira development kit. All of the following tests are designed to run with CSR’s firmware versions Beta 10.4 and above. 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.

Page 51 of 56 BlueCoreTM01 Appendix 2 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. 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.

RegInsert <BlueCore™01> Regulatory Notes & Information 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.
