Re: Slow HTTP server response
Hello, guys! The issue is not related to HTTP/LwIP - it is about WiFi. Please look at this topic for details https://github.com/espressif/esp-idf/issues/7415 . But! The question is still open: why ESP uses WiFi channel so rare, even having goot radio signal and when other devices doe not have such i...

Re: Slow HTTP server response
The thing is when we set the log level to debug, actually the whole system tries to print on the Console. Printing on consoles itself is a time and memory consuming task. My advice is to change the header, log the time taken while entering in the function and while leaving the function. Set the esp...

Re: Slow HTTP server response
I think there is some mistake in the http header. Checkout this. In debug log D (2944441) httpd_txrx: httpd_resp_set_hdr: new header = Content-Disposition: inline; filename=capture.jpg You are responding to the jpg request as inline, but not mentioning the content type as image/jpeg. Either set cor...

Re: Slow HTTP server response
I'm reading your posts with great interest since I am experiencing the same problem. Sometimes, for no apparent reason, a response which usually takes about 1 sec (in human perception terms) will take up to 30 seconds. I am running ESP32 Pico Kit. Your test data is more thorough and detailed than w...

Re: Slow HTTP server response
Another update. After hours of testing with esp32_cam firmware, I've got really unstable results. I tried IDF 4.1 and 4.3 - no remarkable difference. Sometimes, it sends ~100 KB in 300 ms, sometimes in 11000 ms!!! I can't measure actual WiFi readio-channel load, but it looks very strange, because I ...

Re: Slow HTTP server response
UPDATE
It looks like this is some trouble in WiFi or LWIP..
Using Wireshark I see a loot of TCP retransmissions - see attachments.
I'll try to survey on lower layers.
I still hope that this post was read by somebody from Espresiff...

Slow HTTP server response
Hello guys! I am facing strange issue with ESP HTTP server.. I am testing several boards and different firmware and facing the same trouble. I think that esp32-cam would be very goo example to explain. So, I am facing very, very slow responses from HTTP server, when ESP is running in STA mode. Below...

Re: HTTP response with payload via socket send() very slow
Hey!
Any progress here?
i am lso facing something similar.. Though, I use simultaneously: 1) http server based on IDF ESP HTTP server, and 2) custom outgoing requests using lwip socket.
Maybe mixing this isn't good?
Also, I don't see CPU overloads - my IDLE tasks take around 90% time.

Re: Need to run onboarding everytime with Docker and VS Code Extension
OK, I can share the solution now. The problem source is in that the VS Code runs terminal as docker exec ... bash what doesn't run docker ENTRYPOINT script which contains sourcing of /opt/esp/idf/export.sh . I think there are many ways to make this, but I made by adding "terminal.integrated.shellArg...
