BlueTest Instruction Manual Title BlueCoreTM01 Configuration Commands CFG FREQ Sets three values used in deciding timing details of tests. (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. Tx/Rx Int Summary Loopback (lb_offs) sets the offset in microseconds between a reception event and retransmission of the data in loopback.
BlueTest Instruction Manual BlueCoreTM01 Title CFG PKT Sets packet type and size for transmitter tests. It has no effect on RX or LOOP BACK tests. (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 Type Summary (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 .
BlueTest Instruction Manual BlueCoreTM01 Title CFG BIT ERR Sets two values used in bit error measurements. Summary 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 Bits Count = 1 to 4.
BlueTest Instruction Manual BlueCoreTM01 Title CFG TX IF Sets the IF frequency used in transmit test modes. The target is zero, but the stack currently uses a default of -1MHz. Summary 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 Return data None Exit Click on Reset Chip.
BlueTest Instruction Manual Summary BlueCoreTM01 Title CFG XTAL FTRIM 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. (xtal_ftrim) is a number between 0 and 63 inclusive. This is not a permanent change.
BlueTest Instruction Manual 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.
BlueTest Instruction Manual CFG ACC ERRS Summary The receiver uses a sliding correlator to determine that it has matched the start of a packet. The receiver allows up to # of errors (n_errs) before a match is rejected. Related Test Spec Name None Test Arguments # of errors = 0 to 15 (default = 10) Return Data None Exit Click on Reset Chip.

BlueTest Instruction Manual CFG IQ TRIM Summary Sets the IQ Trim (trim) value overriding the value calculated by the internal calibration algorithm. This command is not executed in normal use. Related Test Spec Name None Test Arguments IQ Trim = 0 to 511 (default 149 (hex)) Return Data None Exit Click on Reset Chip.

BlueTest Instruction Manual CFG TX TRIM Summary Sets the Active Member Address (am_addr) for the device to be used in the header of all test transmissions to am_addr. If the transmitter and receiver are used for the same test, both devices will normally have to be set to the same am_addr. Related Test Spec Name None Test Arguments Trim (am_addr) = 0 to 7, Default = 7 Return Data None Exit Click on Reset Chip.
BlueTest Instruction Manual CFG LO LVL Summary Sets the value of the Analogue Local Oscillator output level to LO level (lvl), overriding the value calculated by the internal calibration algorithm.

BlueTest Instruction Manual CFG TX COMP Summary Sets TX Offset (tx_offset) and LO Offset (lo_offset) for the firmware’s algorithm, which sets the maximum power.

BlueTest Instruction Manual BlueCoreTM01 Title PCM LB 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. Summary 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.
BlueTest Instruction Manual BlueCoreTM01 Title PCM EXTERNAL LOOPBACK Sets the PCM into external LOOPBACK mode, whereby the data written to the PCM output is read again on the input pin. 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.
BlueTest Instruction Manual SETTLE Summary Builds the LUT as normal, then does a step from Start Channel (chan1) to Finish Channel (chan2), while the synthesiser is running. It digitises the synthesiser (LO_TUNE) error voltage at intervals of 10 – 20µs over the next 200µs and writes the results to an array.
