你用的是usb电源吧，你换个普通9v电源插那个电源口试试

试了，应该和电源没有关系

那是什么问题呢，谁能解答一下啊

reset的问题解决了，要给uno 的reset和GND之间接10uf 电容

我的好似无这个问题，我的问题是mcu占用时间过长（长时间不调用ether.packetLoop(ether.packetReceive());的话），再发送数据就可以发送不出去，造成丢掉这个数据，现在解决就是mcu运行时间过长的代码，运行结束后就一直调用ether.packetLoop(ether.packetReceive());直到ether.packetReceive()=0。
真不错 ，早就想玩手机 pad 网络控制了，就是安卓开发这块不会啊
使用W5100 制作的3种传感器 数据 上传yeelink成功，http://www.yeelink.net/devices/242
请楼主看下我代码出什么问题了么?向yeelink提交不成功，此外，如何将http response 打印到串口呢？/*

正在 Ping api.yeelink.net 具有 32 字节的数据:
来自 202.136.56.203 的回复: 字节=32 时间=43ms TTL=52

来自 202.136.56.203 的回复: 字节=32 时间=44ms TTL=52
来自 202.136.56.203 的回复: 字节=32 时间=42ms TTL=52ip地址变了。别的好似没问题

可否只添加域名,而不管IP呢?
可以啊，
#include <EtherCard.h>
static byte mymac[] = {
0x74,0x69,0x69,0x2D,0x30,0x31 };
// ethernet interface ip address
static byte myip[] = {
192,168,1,203 };
// gateway ip address
static byte gwip[] = {
192,168,1,1 };
//dns ip address
static byte dnsip[]={
192.168.1.1};
char yeelink_web[] PROGMEM = "api.yeelink.net";
void setup(){
ether.begin(sizeof Ethernet::buffer, mymac);
ether.staticSetup(myip, gwip,dnsip);
ether.dnsLookup(yeelink_web);
}

有人没看见，我顶下哈，顺便补发一张原理图。
static byte mymac[] = {
0x74,0x69,0x69,0x2D,0x30,0x31 };
// ethernet interface ip address
static byte myip[] = {
192,168,1,203 };
这两个要不要改啊，自己的IP和mac？
