I have a soft spot for tiny Macintosh projects, and this one pushes all the right buttons–an ESP32 Cheap Yellow Display board running a Mac Plus emulator inside a 3D-printed case. (...)

Got the ESP-IDE working and tested raw performance with the iperf example from the ESP32S3 to my Desktop. Got roughly 45Mbit/s in both directions.

Meaning the hardware itself is capable.

Now I will write the ESP-IDF version of my snapshot camera program to see if using their examples changes the HTTP-Post throughput.

I also tested my server implementation. This is definitively not the bottleneck. On my small homelab it has no problem with concurrent 30 files/sec

Putting together a #meshcore repeater from some scrap parts and #esp32. No idea what I am doing but it's fun.

Neues Jahr, neues Hobby...

Mein allererster ESP32! Eigentlich hab ich null Zeit für noch'n Hobby, aber Kind 1 (8.Klasse) findet Arduino & Co. gerade spannend, und ich wollte da eh schon lange mal ran.

Wir suchen coole Ideen für den Einstieg! Womit programmiert man sowas eigentlich am besten?

I have these ESP32S3 boards and use the WifiClient.Write method to send the FrameBuffer of a captured Image to a Server endpoint via HTTP-Post.

Everything works well except the Wifi performance of the ESPs is really really bad.

(I use modified Arduino IDE examples as the base)

Sending 40Kb Jpg takes between 500ms to 15 seconds to send. These are only the timings for sending the FrameBuffer.

Anyone a link/tip to a good working example in preferably Arduino IDE?

Woho!

Added a quick reconnect for the wifi. Storing the wifi information like DHCP lease and IP in the RTC memory. Now it takes only 100ms to reconnect the wifi after deepsleep. Before it was 1200ms.

Nice 😃

Switched to a dotnet based server implementation as I am more familiar with it.

Also added the SSIM difference detection directly to the file saving part. Now only images get saved that have more than 5% difference to the previous image of that camera.

Installed it on my homelab and squashed some bugs. Works great so far.

Need to let it run for a couple of days to see about stability.
