您好，我在使用GR5515I0ND 基于SDK1.7.0开发BLE的过程中，遇到以下问题，当5515作为从机向主机ESP32发送大量数据时，发送的中途总是会出现以下错误（0x10）SDK_ERR_NO_RESOURCES，我的蓝牙发送函数如下：

sdk_err_t ebs_tx_data_send(uint8_t conn_idx, uint8_t *p_data, uint16_t length)
{
    sdk_err_t        error_code = SDK_ERR_NTF_DISABLED;
    gatts_noti_ind_t send_cmd;

    if (PRF_CLI_START_NTF == s_ebs_env.tx_ntf_cfg[conn_idx])
    {
        // Fill in the parameter structure
        send_cmd.type   = BLE_GATT_NOTIFICATION;
        send_cmd.handle = prf_find_handle_by_idx(EBS_IDX_TX_VAL, s_ebs_env.start_hdl, (uint8_t *)&s_char_mask);

        // Pack measured value in database
        send_cmd.length = length;
        send_cmd.value  = p_data;

        // Send notification to peer device
        error_code = ble_gatts_noti_ind(conn_idx, &send_cmd);
    }

    return error_code;
}

sdk_err_t app_ble_data_send(uint8_t *p_data, uint16_t length)
{
    sdk_err_t ret_code = BLE_SUCCESS;
    uint16_t loop_cnt = 0;
    uint16_t remainder = 0;
    uint8_t i = 0;
    uint16_t timeout = 0x1000;

    if(!connect_flag)
        return BLE_L2C_ERR_CONNECTION_LOST;

    loop_cnt = length / send_once_size;
    remainder = length % send_once_size;
    for(i = 0; i < loop_cnt; i++)
    {
        g_ble_tx_done = 0;
        ret_code = ebs_tx_data_send(connect_index, p_data + i * send_once_size, send_once_size);
        while(g_ble_tx_done == 0)
        {
            if(timeout)
            {
                timeout--;
            }
            else
            {
                break;
            }
        }
        if(ret_code)
        {
            return ret_code;
        }
    }

    if(remainder)
    {
        g_ble_tx_done = 0;
        ret_code = ebs_tx_data_send(connect_index, p_data + i * send_once_size, remainder);
        while(g_ble_tx_done == 0)
        {
            if(timeout)
            {
                timeout--;
            }
            else
            {
                break;
            }
        }
    }

    return ret_code;
}

请帮忙指导，谢谢
