Description

RW CTEINLINECTRLEN

Enable parsing of CTEInfo from received packet in BLE

modes

Enabled

Parsing of CTEInfo is enabled

Disabled

Parsing of CTEInfo is disabled

RW CTEINFOINS1

CTEInfo is S1 byte or not

InS1

CTEInfo is in S1 byte (data PDU)

NotInS1

CTEInfo is NOT in S1 byte (advertising PDU)

RW CTEERRORHANDLING

Sampling/switching if CRC is not OK

Yes

Sampling and antenna switching also when CRC is not OK

No sampling and antenna switching when CRC is not OK

RW CTETIMEVALIDRANGE

Max range of CTETime

Note: 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 in 8us unit (default)

Set to 20 if parsed CTETime is larger han 20

31 in 8us unit

63 in 8us unit

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 us". When in AoA mode, this is

used when TSWITCHSPACING is 2 us.

RW CTEINLINERXMODE2US

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 2 us". When in AoA mode, this is

used when TSWITCHSPACING is 4 us.
