Re: ESP8266 transmisson data in lan

网络堵塞呗。。你开车上班,早高峰堵车了,你就算开奔驰也只能被堵在路上。。。
照理说,它会不断尝试发送,但如果一直发不出去,它就会提示网络断开了。。

Re: ESP8266 Sends UDP data

Try station_only mode when calling wifi_set_opmode. And also call wifi_set_broadcast_if (STATION_MODE); to enable broadcast in the station mode.

AT 占用了 UART,你重新初始化 UART,AT 就用不了吧。。

Re: ESP8266 Fatal exception (3) 无法正常启动

你可以做开关机测试,dump flash 对比正常启动的 flash 数据,和异常后的 flash 数据是否发生了变化。
当然这样最好就烧个啥事也没做的应用程序,排除是应用程序改写了 flash。

Re: Is it possible to wakeup esp8266 from light sleep periodically and by the button press.

If there is a timer active, the ESP cannot sleep, you can refer to the ESP8266 non OS API Guide, which provided an example of light sleep.
