User’s Manual
**Comply with the Loopback Mode restrictions in I:4, section 2.2 of the 1.1 Bluetooth
spec.
Return
• "Success"
•"Failure"
• "Device not connected"
• "Invalid parameters"
Return value
² "Success"
² "Failure"
ErrorMask
2 Bytes
0 Random error
distribution
If ErrorType is not zero, this parameter is valid. It
defines error distribution.
For FEC 2/3, random error distribution, one error
bit will be inserted in every 15-bit packet. Valid
for DM packet types
For FEC 1/3 header, random error distribution,
one error bit will be inserted in every 3-bit packet.
Valid for all packet types with the header
For FEC 1/3 payload, random error distribution,
one error bit will be inserted in every 3-bit packet.
Valid for DH1 packet type.
>0 Set bits indicate error
positions within 15-bit
mask for FEC 2/3
Tx Jitter
1 Byte
0 No jitter is added Random jitter between -10 and +10us is added to
the nominal 1250 us Master Tx timing. The value
is 2's compliment. 0.5us is supported. For
example, 64 will give a jitter of 0.5us, 70 will give
jitter of 5.5us
Example of Jitter values are:
0-10 Jitter 0 to10, w/o 0.5us
64-74 Jitter 0 to10, w/ 0.5us
-64 to -74 Jitter -1 to -10, w/ 0.5us
-1 to -10 Jitter -1 to -10, w/o 0.5us
N=
0x00
0xFF
Random jitter up to N
us is added.
