ESP8266访问网页和NTP不定时会重启

28674500 · 发表于 2020-2-10 12:24:59

程序都是数码之家大神写的，我只是合并了一下。
程序设定的是10秒读取一次NTP时间，30分钟访问一次天气网页
但是，30分钟左右必定重启一次
麻烦大神分析一下
是不是一直访问网页，导致内存满了？负荷过重？该如何处理
2345截图20200209212739.png

代码如下

/*
1,本人能力有限，程序存在BUG，目前问题是30分钟不到不定时重启。
2,程序为10秒获取一次时间，30分钟获取一次天气数据。
3,请登陆京东云【http://wx.jdcloud.com/market/datas/26/10610】获取APPKEY。
注意：未登陆直接“点击获取”APPKEY的“4ae4a2fcf405ce9beca0109018101d10”为无效APPKEY。
4,获取步骤：打开网址---点击立即测试---登陆（没注册的需要注册）---重新打开网址---点击立即测试即会出现APPKEY。

有时候是模块的问题:lol:，我有一个模块，经常掉线，换了一个模块后好了

xlmttkl · 发表于 2020-2-10 15:48:24

试试在void loop() 里面加一句 ESP.wdtFeed(); 喂下看门狗,极大可能是看门狗引发的复位,我以前也遇到过几个小时后莫名其妙重启的,加了就好了,还有delay延时一次不要太长,也容易引发看门狗复位

通过打印返回空间堆大小，每次运行必定减少424，到最后不够减时，就重启了。

为何10秒就同步ntp？一个星期或启动时同步一下就好了。

NTP用官方的就好了，不要自己写，还有时间，日期，星期也不用自己算，直接调用time.h，然后用hour()之类的取就行。

while (Udp.parsePacket() > 0) ; // discard any previously received packets
// Serial.println("Transmit NTP Request");
// get a random server from the pool
WiFi.hostByName(ntpServerName, ntpServerIP);
// Serial.print(ntpServerName);
// Serial.print(": ");
// Serial.println(ntpServerIP);
sendNTPpacket(ntpServerIP);
uint32_t beginWait = millis();
while (millis() - beginWait < 1500) {
int size = Udp.parsePacket();
if (size >= NTP_PACKET_SIZE) {
// Serial.println("Receive NTP Response");
Udp.read(packetBuffer, NTP_PACKET_SIZE); // read packet into the buffer
unsigned long secsSince1900;
