HTTPD and short lived connections and limit 16

Given the extremely tight budget of TCP connections at 16, I want to disable persistent connections. I would also like the http server to automatically limit the number of connections it takes, say to 10, and the fancy feature would be to check and kill the oldest connection if it gets to 8 ( n - 2)...

WiFiMulti for esp-idf available

When I started using ESP-IDF, I realized I needed a wifi manager. I always have quite a few wifi APs and if I'm going to use wifi I need to not brick it. If you're doing OTA, you need a network before you can Update! The 'WiFiMulti' system in Arduino is awesome - so I thought I would start building ...

ESP32-PICO-D4 and USB ?

I wired some some LEDs for a small art project to a DevKitC 4.1 made by espessif, and I find that when I use GPIO18, reflashing the board is more cumbersome. That is, the LEDs start blinking like crazy when I use idf.py flash, showing that someone else is using the pin, and I need to manually hit th...

Re: FastLed

I have just ported the FastLED 3.3.4 code as a component that works with ESP-IDF 4.0. The repository is here: https://github.com/bbulkow/FastLED-idf . If you like it, star it, thanks. Pull requests accepted as well. There are copious notes in the README, and I'll continue improving it --- but seems ...

4.x supports removing unnecessary code modules?

I was watching during compile, and I see the PPP module, which is experimental and disabled, being compiled and linked. Reading through, I see that one can make big static lists of components - but removing components will obviously always be hard. Only in cases like PPP, where there are unlikely to...

Re: Realtime Firebase

Firebase uses HTTP posts of JSON data. The ESP-IDF system does have both JSON and HTTP. Have you hooked up the HTTP server and gone through the examples? Same with JSON? Then followed the guides regarding how to format your JSON and HTTP URI for Firebase? Arduino always has more users so will have b...

Re: Firsttimer Impressions of ESP32 IDF

Regarding "VS Code", please do not relegate users to Visual Studio! You support command line use of esp-idf quite nicely, thank you, and I would only propose you move your windows support from the DOS (CMD) shell, to the WSL shell. The system works very nicely, and only needs a few changes to the do...

Re: Firsttimer Impressions of ESP32 IDF

Thanks for the thoughts. I am running "WSL1". I tried WSL2 and read up on it, and from what I understand so far, WSL1 is better for me. The main reason for going in that direction seems to be improved performance of the Linux file system which is inaccessible to the "regular windows" processes, and ...

Firsttimer Impressions of ESP32 IDF

Hello, I thought i would share some impressions / requests. First, I believe ESP-IDF should consider Windows WSL a first-category environment, and abandon MINGW MSYS. While I've used those tools plenty in the past ( 90's embedded tool chains, notably ), the reality is that WSL is now a supported par...
