使用 mosquitto_pub -h 192.168.1.218 -t start -m "123456789" -r 发布消息，订阅此话题的客户端（开发板）收到retain消息后，发现此消息丢失了2个字节，如下： 603 [topic: start] 3456789，每次测试都会复现，是我在使用上有什么问题吗？

How to write firmware onto the XR871_EVB_MAIN_BRD_V_1_1 using Linux?

Following document explains how to build firmware on both Windows and Linux:

https://github.com/XradioTech/XR871/blob/master/03_SDK/XR871_Quick_Start_Guide-CN.pdf

But the document doesn't write the firmware using Linux. May I use https://www.segger.com/downloads/jlink to write the firmware?

应该加上这个标志，否则按键定时器还没有创建就跑到这了，会导致初始化重启

Why do I see noises? I checked the contacts to tx rx everything is fine.

xr871SDk的src/net下已经有编译好的paho.mqtt.embedded-c， 我试着仿照paho.mqtt.embedded-c下的sample，编写一个mqtt demo，但在xr871上一直运行不起来，socket方面估计要移植更改下 ，能给些指导性意见吗

这个怎么处理啊

need web socket guideline

please share the developer information that in english since many informations are in chinese only, very hard to understand -

Ubuntu 18,04通过git命令行
Windows 10通过TortoiseGit工具

clone下来后都会产生乱码，并且Windows 10重命名后再提交，diff依然不会消失。
