connection#

uint8_t sl_bt_evt_cs_result_s::connection

Connection handle. Returns a SL_BT_INVALID_CONNECTION_HANDLE (0xFF) when triggered as a result of sl_bt_cs_test_start command

config_id#

uint8_t sl_bt_evt_cs_result_s::config_id

CS configuration identifier

• Range: 0 to 3

start_acl_conn_event#

uint16_t sl_bt_evt_cs_result_s::start_acl_conn_event

Starting an ACL connection event count for the results reported in the event. This is reported only in the first subevent in the procedure. For subsequent subevents, this value is set to 0.

procedure_counter#

uint16_t sl_bt_evt_cs_result_s::procedure_counter

Indicates the associated CS procedure count for the results reported in this event

frequency_compensation#

int16_t sl_bt_evt_cs_result_s::frequency_compensation

Frequency compensation value. Units: 0.01 ppm (15-bit signed integer).

• Range: -10000 to 10000

• Value: 0xC000. Frequency compensation value is not available or the role is not initiator. This is reported only in the first subevent in the procedure. For subsequent subevents, this value is set to 0.

procedure_done_status#

uint8_t sl_bt_evt_cs_result_s::procedure_done_status

Enum sl_bt_cs_done_status_t. Current status of the CS procedure Values:

• sl_bt_cs_done_status_complete (0x0): All results complete for the CS procedure or subevent

• sl_bt_cs_done_status_partial_results_continue (0x1): Partial results with more to follow

• sl_bt_cs_done_status_aborted (0xf): Current procedure and all subsequent subevents in the procedure aborted or current subevent aborted.

subevent_done_status#

uint8_t sl_bt_evt_cs_result_s::subevent_done_status

Enum sl_bt_cs_done_status_t. Current status of the CS subevent Values:

• sl_bt_cs_done_status_complete (0x0): All results complete for the CS procedure or subevent

• sl_bt_cs_done_status_partial_results_continue (0x1): Partial results with more to follow

• sl_bt_cs_done_status_aborted (0xf): Current procedure and all subsequent subevents in the procedure aborted or current subevent aborted.

abort_reason#

uint8_t sl_bt_evt_cs_result_s::abort_reason

Enum sl_bt_cs_abort_reason_t. Indicates the abort reason when the procedure_done_status or subevent_done_status is set to 0xF, otherwise the default value is set to zero. The first 4 bits are related to the procedure abort reasons and the last 4 bits are related to the subevent done. Values:

• sl_bt_cs_abort_reason_no_abort (0x0): Not aborted

• sl_bt_cs_abort_reason_host_request (0x1): Local or remote host request

• sl_bt_cs_abort_reason_insufficient_channels (0x2): Filtered channel has less than 15 channels

• sl_bt_cs_abort_reason_no_map_update (0x3): Channel map update instant has passed

• sl_bt_cs_abort_reason_busy (0xb): Controller busy with other CS Procedure

• sl_bt_cs_abort_reason_sync_error (0xc): Mode-0 packet exchanges failure

• sl_bt_cs_abort_reason_scheduling_conflict (0xd): Link Layer failed to schedule the CS procedure

• sl_bt_cs_abort_reason_radio_failure (0xe): Radio error

• sl_bt_cs_abort_reason_unspecified (0xf): Unspecified reasons for abortion

reference_power_level#

int8_t sl_bt_evt_cs_result_s::reference_power_level

Reference power level used by the transmission. Units: dBm.

• Range: -127 to +20

• Value: 0x07F. The reference power level is not applicable

num_antenna_paths#

uint8_t sl_bt_evt_cs_result_s::num_antenna_paths

Number of antenna paths supported by the local controller for the CS tone exchanges. The number of antenna paths used during the phase measurement stage of the CS step.

• Range: 1 to 4

• Value: 0. Phase measurement does not occur during the CS step, therefore ignored

num_steps#

uint8_t sl_bt_evt_cs_result_s::num_steps

Number of steps in the CS subevent for which results are reported.

• Range: 1 to 160

data#

uint8array sl_bt_evt_cs_result_s::data

The result data is structured as follows:

• step_status: 1 octet for each num_steps. 0x00 for step scheduled and reported. 0xFE for step aborted.

• step_mode: 1 octet for each num_steps. Mode type. Range 0 to 3.

• step_channel: 1 octet for each num_steps. Channel index. Range 1 to 78.

• step_data_length: 1 octet for each num_steps. Length of mode and role specific information being reported. Range 0x00 to 0xFF.

• step_data: step_data_length octet for each corresponding steps in num_steps.
