hi @hibfh , in your application, do you keep the AP pn all the time? or you try to disable or enable it sometimes?

[hibfh]

@Xiehanxin What do you mean by "PN"?is it "on"? My app keep AP all the time .maybe it needs to stop for a while？I think my app keep AP on about over 3 hours and hit the trouble. btw, what may cause the strange hidden ssid in win10 ?

[hibfh]

The second trouble is solved now

[Xiehanxin]

hi @hibfh did you download large files or need high througput? sometimes too much HTTP callback can make the watch dog

[hibfh]

hey @Xiehanxin ，i had no http task but a huge TCP throughput task running that time, did it cause the wdt time out? Recently,I fix some bug like memory fragmentation,tcp fd not close after wifi disconnect ,and it works well so far.maybe it was solved.
