Title BIT ERR2

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

Summary

RXDATA2.

Returns information on bit errors to the host as those given for

BIT ERR1 .

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.

Country Code = 0 to 3 (default 0)

hi-side = 0 or 1 (default = 0)

RX Attenuation = 0 to 15 (default = 0)

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 .

Title CFG FREQ

BlueTest Instruction Manual

Summary

Related Test Spec Name

Test Arguments

Return Data None.

Sets three values used in deciding timing details of tests.

Tx/Rx Int (txrx_freq) sets the period in microsec onds

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 microsec onds

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 unchange d. None

TX/RX Int (µS) = 1 to 65535 (default = 1250) Loopback (µS) = 1 to 65535 (default = 1875)

Report Int (S) = 1 to 65535 (default = 1)

Title CFG PKT

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.

Summary

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.
