HTTPS Server keep creating new connections

I'm having a HTTP server using esp-idf's esp_http_server library and it's working well.

This make my web page load very v...

Re: Libwebsockets with FatFS

Smells like memory corruption (assert in the heap allocator) that then tries to panic but can't properly, likely because of the aforementioned memory corruption. Thanks for verify that. That memory corruption means some memory leak and not properly free right? It always failed when accessing the fi...

Libwebsockets with FatFS

I've successfully run HTTPS server using libwebsockets with esp-idf release v4.2.

Everything worked well, until I tried accesing FatFs in the esp32.... Either read or write even fseek will cause it calling abort and reboot...

Any idea or possible causes of the problem?

I'm using ESP-IDF 4.2, I've set IP_SOF_BROADCAST and IP_SOF_BROADCAST_RECV to 1 in opt.h as suggested. I've set socket options of SO_BROADCAST and bind the socket to INADDR_ANY too. A...

Re: APSTA Mode - STA connected but not accessible after random period of time

I spent quite some time to troubleshoot, I think it's the ARP table issue. I found that after I switching the WIFI connections of my PC (my esp32 and PC connected to router by default) to esp32's AP, then back to router, the ARP table in my PC do not have the record of my esp. If I add in the ARP en...
