Could you please also post liblwip_536.a ? Thanks!

FYI for others: without this patch a fatal exception causing reset gets triggered if you call espconn_abort() on a connection that is actively receiving data.

I am finding that in prototyping situations the fact that gpio0 outputs the 26Mhz clock can cause quite some noise issues. Cables, etc. Since gpio0 has to be pulled high or low in order to control the boot mode, it has to be connected to the programmer, often via a cable. Is there a way to toggle re...

You're misunderstanding TOUT. A TOUT value of N means: "if you have not received any new character in N time units then an interrupt is fired. A time unit is the time it takes to receive 8 bits."

Your test is faulty...
You can get an interrupt when the fifo reaches a fill level you set or when there are characters in the fifo and nothing new has been received in a time period you set.

You should email to the bug bounty address (bugbounty@espressif.com), it's detailed in the bug bounty program write-up. I've always gotten a response with 2-3 days.

SDK 1.5.0 is missing liblwip_536.a, can you please provide it? It's pretty critical in memory constrained firmwares that need to support many connections. Thank you!

FYI: I was using lib1.4.1_pre7, I will see whether I can produce a small project that exhibits the problem.
NB: The lib1.4.1_pre7 archive is missing liblwip_536.a

@Espressif_Faye can you please provide liblwip_536.a for SDK v1.4.1_pre7 ?
Thanks!

When I enable mDNS using SDK 1.4.1_pre7 I get "already freed" errors: 5658> ip:192.168.0.151,mask:255.255.255.0,gw:192.168.0.1 5658> Wifi got ip:192.168.0.151,mask:255.255.255.0,gw:192.168.0.1 5660> host_name = esp-link4 5663> server_name = _http._tcp.local 12525> pm open phy_2,type:2 0 0 ...

I have the same problem with the "already freed" errors using V1.4.1_pre7 from http://bbs.espressif.com/viewtopic.php?f=7&t=1257&start=10#p4505 Did the fix in the liblwip.a from this thread get lost in the _pre7 version? I am also seeing problems where mDNS does not reply to certai...
