BlueTest Instruction Manual bc01-an-047b © Copyright CSR Ltd 2001 This material is subject to CSR’s non-disclosure agreement. Page 21 of 56 BlueCoreTM01 Title BER LOOP BACK Summary Transmit PRBS9 data on LO Frequency at transmit level and listen for transmissions in the next slot but one. Sends reports as BIT ERR1 back to the host once per second (configurable). Highside reception is off and attenuation is set to zero Default is single slot packets (configurable with config_freq). Designed to be used with a second unit in loop_back test mode. Related Test Spec Name None, but note that this test allows transmission to and reception from IUT in loopback test mode, with calculation of BER to BT specification. Called via BCSP channel 2 Test Arguments LO Freq (Carrier Frequency MHz)= 2402 to 2480 Power (Ext, Int) = gain of external amplifier (if present) and internal amplifier. Ext value is specific to the design and Int value is 0 to 63 (Default = 50). Note With a second unit execute CFG UAP/LAP to set BT address then execute LOOP BACK, then execute CFG UAP/LAP to set the same BT address on the EUT before executing BER LOOP BACK. Return Data Nine reports as for BIT ERR1. Exit Click on Reset Chip. BER LOOP BACK Example Display
BlueTest Instruction Manual bc01-an-047b © Copyright CSR Ltd 2001 This material is subject to CSR’s non-disclosure agreement. Page 22 of 56 BlueCoreTM01 Configuration Commands Title CFG FREQ Summary Sets three values used in deciding timing details of tests. Tx/Rx Int (txrx_freq) sets the period in microseconds between TX and RX events in RXDATA, TXDATA, BIT ERR and LOOP BACK test modes. Default is 1250 (20 slots), maximum 65536. If passed as 0, current value unchanged. Loopback (lb_offs) sets the offset in microseconds between a reception event and retransmission of the data in loopback. Default is 1875 (two slots later), must be less than TX/Rx Int (txrx_freq). If passed as zero current value unchanged. Report Int(report_freqs) sets the time in seconds between reports to host sent by RXDATA and BIT ERR functions. Default 1, if passed as 0 current value unchanged. Related Test Spec Name None Test Arguments TX/RX Int (µS) = 1 to 65535 (default = 1250) Loopback (µS) = 1 to 65535 (default = 1875) Report Int (S) = 1 to 65535 (default = 1) Return Data None. Exit Click on Reset Chip. CFG FREQ Example Display
BlueTest Instruction Manual bc01-an-047b © Copyright CSR Ltd 2001 This material is subject to CSR’s non-disclosure agreement. Page 23 of 56 BlueCoreTM01 Title CFG PKT Summary Sets packet type and size for transmitter tests. It has no effect on RX or LOOP BACK tests. Packet Type (pkt-type) is the standard Bluetooth packet type, 0-15 (12-13 not allowed). Any other number sets default: DM5 for TXDATA1/2, DH5 for TXDATA3/4. Packet Size (pkt_size) is the size of data in packet, from one to maximum for type. If zero sets default: 20 bytes for TXDATA1/2, 192 bytes for TXDATA3/4. Since the two values are connected both values must be set – no default is inferred. Related Test Spec Name None Test Arguments Packet Type = 0 to 15 (default = 4) (see Appendix 5) Packet Size = 0 to 339 (default = 27) Return data None Exit Click on Reset Chip.

BlueTest Instruction Manual bc01-an-047b © Copyright CSR Ltd 2001 This material is subject to CSR’s non-disclosure agreement. Page 24 of 56 BlueCoreTM01 Title CFG BIT ERR Summary Sets two values used in bit error measurements. If Bits Count (bits_count) is non-zero, the target for total counters is set to this and total count resets at this value. If passed as 0 current value, unchanged. If Reset is not false and BIT ERR/2 is active, immediately resets the counters for the total statistics, but not over the last report period. Related Test Spec Name None Test Arguments Bits Count = 1 to 4.2 x 109 (default = 1600000 Bit) Reset = false (0) or true (1) (default = false) Return Data None Exit Click on Reset Chip.

Page 25 of 56 BlueCoreTM01 Title CFG TX IF Summary Sets the IF frequency used in transmit test modes. The target is zero, but the stack currently uses a default of -1MHz. Offset is a signed integer with a range from +5 to –5, in units of 0.5MHz. Related Test Spec Name None Test Arguments IF Offset = -5 to +5 (default = 0) Return data None Exit Click on Reset Chip.

Page 26 of 56 BlueCoreTM01 Title CFG XTAL FTRIM Summary Timing for BlueCore01 is controlled by a crystal. This requires trimming for new hardware. This command can be used to set a new trim value either before a radiotest command is started or while a test is already in operation; the change takes effect immediately. Crystal Trim (xtal_ftrim) is a number between 0 and 63 inclusive. This is not a permanent change. Related Test Spec Name None Test Arguments Crystal Trim = 0 to 63 (typical = 27) Note With Crystal Trim set to 0, the current settings will not change. Return data None Exit Click on Reset Chip.

BlueTest Instruction Manual bc01-an-047b © Copyright CSR Ltd 2001 This material is subject to CSR’s non-disclosure agreement. Page 27 of 56 BlueCoreTM01 Title 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. Related Test Spec Name None Test Arguments Bluetooth Address: UAP = 0 to FF (Default = 6b) LAP = 0 to FFFFFF (Default = c6967e) Return Data None Exit Click on Reset Chip. CFG UAP/LAP Example Display

Page 35 of 56 BlueCoreTM01 Title PCM LB Summary Sets the PCM into LOOP BACK mode, whereby the data read from the PCM input is output again on the PCM out pin. The LOOP BACK is via software and the buffers so there is a pipeline delay. The PCM port mode is selectable. If PCM Mode = 0, BlueCore01 is slave in normal 4-wire configuration If PCM Mode = 1, BlueCore01 is master in normal 4-wire configuration If PCM Mode = 2, BlueCore01 is master in Manchester encoded, 2-wire configuration.
