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.
