Sub-Device Standard Group

Standard group enables the user to manage sub-devices of the same type in bulk.

Description

A device group allows the user to instruct devices of the same type to execute the same type of actions in bulk.

How it works

How to

• Implement the processing of DTT_SCT_MNC in dtt_tp for the object-type sub-device.
• Implement the callback for dev_grp_info in device management.
• Call tuya_subdev_user_sigle_type_reg to register the sub-device management interface.

API description

Register sub-device interfaces

/**
  * @brief register callback with protocol type
  *
  * @param[in] p_user_dev_node_cbs callback, see TY_GW_SUBDEV_MGR_CBS_S
  * @param[in] user_dev_type       custom protocol type, range from 10 to 19
  *
  * @return OPRT_OK on success. Others on error, please refer to tuya_error_code.h
  */
OPERATE_RET tuya_subdev_user_sigle_type_reg(TY_GW_SUBDEV_MGR_CBS_S *p_user_dev_node_cbs, BYTE_T user_dev_type);

The sub-device registers interface functions. You need to implement the callback for dev_grp_info. If you need other functions, implement the callback accordingly.

Example

STATIC VOID __dev_cmd_obj_cb(CONST TY_RECV_OBJ_DP_S *cmd)
{
    if(DTT_SCT_MNC == cmd->dtt_tp){
        if(dp->obj_dp->dps_cnt > LG_SCE_EP_MAX_NUM){
            PR_ERR("dps cnt err dps_cnt:%d",dp->obj_dp->dps_cnt);
            return OPRT_COM_ERROR;
        }
    }
}

OPERATE_RET __gw_grp_cb(IN CONST GRP_ACTION_E action,IN CONST CHAR_T *dev_id,IN CONST CHAR_T *grp_id)
{
    PR_DEBUG("action:%d dev_id:%s grp_id:%s",action,dev_id,grp_id);
    if( action == GRP_ADD ){
        // add group
    } else if( action == GRP_DEL ){
        // delete group
    } else {
        PR_ERR("value err");
        return OPRT_INVALID_PARM;
