标题: 蓝牙主机on_descriptor_discovery_rsp不断重启
开发板：NRF52832
协议栈版本：132
使用从机串口例程和主机串口例程后想试试把从机代码换为蓝牙通知的例程，然后改了一下主机串口中对应的UUID设置发现程序在找到cccd后就莫名重启了，串口日志如下：

红色部分是重启了，上面的打印信息插在代码如下位置：

    if (perform_desc_discov)
    {
            uint32_t i;
                for(i = 0; i < p_srv_being_discovered->char_count; i++)
                        printf("%d char UUID is %x\r\n",i+1,p_srv_being_discovered->charateristics.characteristic.uuid.uuid);
        bool raise_discov_complete;

        p_db_discovery->curr_char_ind = 0;

        err_code = descriptors_discover(p_db_discovery,
                                        &raise_discov_complete,
                                        p_ble_gattc_evt->conn_handle);
                printf("**************************\r\n");
                printf("raise_discov_complete:%x\r\n",raise_discov_complete);

        if (err_code != NRF_SUCCESS)
        {
                printf("descriptors found exception.\r\n");
