Title BIT ERR2
Summary
Enables the receiver with simplified hopping defined by Country
Code with a choice of low or high side modulation (hi-side), and
with a designated attenuation setting (RX Attenuation) as for
RXDATA2.
Returns information on bit errors to the host as those given for
BIT ERR1.
Related Test Spec
Name
None, but note that this test allows (as in BIT ERR1) the tests
RCV/CA/01/C and RCV/CA/02/C (sensitivity), RCV/CA/04/C
(blocking performance) to be performed with hopping on. This is
a more thorough test than that possible with the 7 Layers
equipment.
Test Arguments
Country Code = 0 to 3 (default 0)
hi-side = 0 or 1 (default = 0)
RX Attenuation = 0 to 15 (default = 0)
Note
With a second unit, execute CFG UAP/LAP to set BT address
then execute TXDATA2, then execute CFG UAP/LAP to set the
same BT address on the Equipment under Test (EUT) before
executing BIT ERR2.
Return Data Nine reports, each two uint32 values as for BIT ERR1.
Exit Click on Reset Chip.

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.

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.

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.

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.
