Description
InS1
1
CTEInfo is in S1 byte (data PDU)

0
CTEInfo is NOT in S1 byte (advertising PDU)
C
RW CTEERRORHANDLING
Sampling/switching if CRC is not OK
Yes
1
Sampling and antenna switching also when CRC is not OK
No
0
No sampling and antenna switching when CRC is not OK
E
RW CTETIMEVALIDRANGE
Max range of CTETime
Valid range is 2-20 in BLE core spec. If larger than 20, it can
be an indication of an error in the received packet.
20
0
20 in 8 µs unit (default)
Set to 20 if parsed CTETime is larger than 20

F
RW CTEINLINERXMODE1US
Spacing between samples for the samples in the
SWITCHING period when CTEINLINEMODE is set.
When the device is in AoD mode, this is used when the
received CTEType is "AoD 1 µs". When in AoA mode, this is
used when TSWITCHSPACING is 2 µs.

S0 bit mask to set which bit to match
The least significant bit always corresponds to the first bit of
S0 received.
