移植到mips平台出现问题，请帮忙看看日志，给点提示 #6

编译没有错误，能正常运行，同样配置直接在ubuntu下编译后能正常连接到服务器

看日志，返回的错误码为-111，可以参看qcloud_iot_export_error.h头文件，为QCLOUD_ERR_MQTT_REQUEST_TIMEOUT = -111 表示MQTT相关操作请求超时，这个可能和设备的网络环境有关系。 建议修改qcloud_iot_export.h头文件中，下面的两个宏定义为10*1000，试一下

/ MQTT 阻塞调用(包括连接, 订阅, 发布等)的超时时间, 单位:ms 建议5000ms /

define QCLOUD_IOT_MQTT_COMMAND_TIMEOUT (5 * 1000)

/ TLS连接握手超时时间, 单位:ms /

define QCLOUD_IOT_TLS_HANDSHAKE_TIMEOUT (5 * 1000)

感谢

修改了上述两个参数后仍然是同样错误

skyztmeng commented 5 years ago

检查一下网络环境是好的么？

tuy0326 commented 5 years ago

网络环境正常

skyztmeng commented 5 years ago

查了一下后台日志，后台显示这个设备最近一次连接上了平台，时间是10:54，不知道这个是不是ubuntu的连接，按理说，同样的代码，在ubuntu上可以连接，说明逻辑没有问题，还请麻烦检查一下mips平台相关的环境，是否大小端，网络字节序不一样？

tuy0326 commented 5 years ago

10:54的这次是x86 ubuntu平台连接的

tuy0326 commented 5 years ago

不知道编译环境中是否有配置工具链的一些选项，这个编译环境我编译其它具有网络连接的软件是正常的

skyztmeng commented 5 years ago

pc是小端模式，mips是大端模式，有可能和这个相关，SDK中有个REVERSED宏定义，和大小端相关， ./src/mqtt/include/mqtt_client.h:92:#if defined(REVERSED) ./src/mqtt/src/mqtt_client_connect.c:29:#if defined(REVERSED) ./src/mqtt/src/mqtt_client_connect.c:55:#if defined(REVERSED) 麻烦在编译选项中定义下，这个宏定义，看一下能否连接上

tuy0326 commented 5 years ago

嗯，确实是这个问题，非常感谢
