使用at client功能接收响应时显示堆栈溢出（新手请教）

本人新手，使用AT组件开发移远BC95模块。串口发送正常，接收时finsh打印出thread heap stack overflow，和所有线程都挂起的信息。
不知道是哪里出了问题，是有地方没有配置还是程序本身问题？请指教，以下为程序源码：

static void bc95_init_thread_entry(void *parameter)
{
#define CIMI_RETRY			10
#define CSQ_RETRY			  10
#define CRGE_RETRY			10
#define CGREG_RETRY			20

at_response_t  resp = RT_NULL;
	rt_err_t       result = RT_EOK;
	int	           i;
	char		       parsed_data[10];
	
	resp = at_create_resp(128, 0, rt_tick_from_millisecond(300));
	if(!resp)
	{
		LOG_E("No memory for response structure!");
		result = -RT_ENOMEM;
		goto __exit;
	}
	LOG_D("Start initializing the BC95 module");
	/*wait BC95 starup finish*/
	if(at_client_wait_connect(BC95_WAIT_CONNECT_TIME))
	{
		result = -RT_ETIMEOUT;
		goto __exit;
	}
	/* disable echo */
    AT_SEND_CMD(resp, 300, "ATE0");
	/* get module version */
    AT_SEND_CMD(resp, 300, "ATI");
    /* show module version */
    for (i = 0; i < (int) resp->line_counts - 1; i++)
    {
        LOG_D("%s", at_resp_get_line(resp, i + 1));
    }
	/* check SIM card */
    for (i = 0; i < CIMI_RETRY; i++)
    {
        at_exec_cmd(at_resp_set_info(resp, 128, 2, rt_tick_from_millisecond(5000)), "AT+CIMI");

        {
