cts_local_time_write

int(* bt_cts_cb::cts_local_time_write) (const struct bt_cts_local_time *cts_local_time)

It is the responsibility of the application to store the new Local time.

Parameters

[in]

local_time

Requested local time to write

Returns

0 if written successfully, negative error code on failure

cts_time_write

int(* bt_cts_cb::cts_time_write) (struct bt_cts_time_format *cts_time)

The Current Time has been requested to update by a peer.

It is the responsibility of the application to store the new time.

Parameters

[in]

cts_time

Requested time to write

Returns

0 if written successfully, negative error code on failure

fill_current_cts_local_time

int(* bt_cts_cb::fill_current_cts_local_time) (struct bt_cts_local_time *local_time)

Request to get current local time.

CTS uses this callback to retrieve local time information from application. Application must implement it and provide cts local time information

Parameters

[out]

local_time

Current local time struct to be filled

Returns

0 if filled successfully, negative error code on failure

fill_current_cts_time

int(* bt_cts_cb::fill_current_cts_time) (struct bt_cts_time_format *cts_time)

Callback to get current time.

When current time Read request or notification is triggered, CTS uses this callback to retrieve current time information from application. Application must implement it and provide cts formatted current time information

Parameters

[out]

cts_time

Current time for the application to be filled

Returns
