range_update

void(*const bt_mesh_lightness_srv_handlers::range_update) (struct bt_mesh_lightness_srv *srv, struct bt_mesh_msg_ctx *ctx, const struct bt_mesh_lightness_range *old_range, const struct bt_mesh_lightness_range *new_range)

The Light Range state has changed.

The user may implement this handler to subscribe to change to the Light Range state. If the change in range causes the current Light state to be out of range, the Light state should be changed to the nearest value inside the range. It is recommended to call bt_mesh_lightness_srv_pub to notify the mesh if the Light state changes.

Parameters

[in]	srv	Server the Light Range state was changed on.
[in]	ctx	Context of the set message that triggered the update, or NULL if it was not triggered by a message.
[in]	old_range	The Light Range before the change.
[in]	new_range	The Light Range after the change.
