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
LO Freq (Carrier Frequency MHz)=
Test Arguments
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.

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. 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.

Spec Name
None
TX/RX Int (µS) = 1 to 65535 (default = 1250)
Test Arguments
Loopback (µS) = 1 to 65535
Report Int (S) = 1 to 65535

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 .
Packet Size
Since the two values are connected both values must be set – no
default is inferred.

Spec Name
None
Packet Type = 0 to 15 (default = 4) (see Appendix 5)
Test Arguments
Packet Size = 0 to 339 (default = 27)
Return data
None

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.

Spec Name
None
Bits Count =
1 to 4.2 x 109 (default = 1600000 Bit)
Test Arguments
Reset =
false (0) or true (1) (default = false)

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.

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.

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.
