Re: Intermittent HTTP client request failures
Thank you a2800276. It turned out to be a hardware problem. I built the board using a CMOS oscillator for the W5500 chip thinking that it would work even if the W5500 expected TTL. I though that would work if output was CMOS and TTL input (not the other way round tho). Seems I was wrong. Funny that ...

Intermittent HTTP client request failures
Hi, I have an ESP32 connected to a W5500 ethernet IC. I have a program that starts by doing some GETs and then starts a infinite routine that does POSTs of a small Base64-encoded image once a minute. The problem is that about 50% of the times I get E (153964) TRANSPORT_BASE: tcp_write error, errno=C...

Force SNTP update
Hi, I have SNTP running on my ESP32. My understanding is that the internal clock has about 5% error. Because of this I want to get an SNTP update exactly before doing a task that requires precise timing. Is it possible to force a SNTP update? I can't find anything in the docs.
Thank you!
Thank you!

ESP32-CAM I2C conflict
Hi, I have a ESP32-CAM I am using for taking pictures. I am also using a PCF8574 for GPIO expansion connected via I2C. Both the camera and the expansion chip work when ran independently but not at the same time. I've configured the camera to use I2C Port1 and PCF8574 to use Port0. The code starts wi...

Re: esp_http_client PSRAM use
Yes. It is detected at the beginning but nevermind, I already found the issue. The problem is that I am using pin 16 for the w5500 module and it turns out that the ESP32-CAM also uses that for PSRAM chip select!
Thank you!
Thank you!

Re: esp_http_client PSRAM use
Hmm interesting, I disabled PSRAM and it is indeed working without it! However I do need the PSRAM for storing some images in it and currently I am unable to due to this issue. For some reason the moment I do the w5500 init the PSRAM goes to 0. Is there a possible explanation aside of a hardware/pow...

Re: esp_http_client PSRAM use
I am doing heap_caps_get_free_size(MALLOC_CAP_SPIRAM) to get the available external RAM. I dug a bit deeper and the problem seems to be when initializing the MAC part of the w5500 ethernet module I am using. But still not sure what is going on. I think it's a bit suspicious that after initializing I...

esp_http_client PSRAM use
Hi, I am planning of using the esp_http_client component for a project. I started by checking out the esp_http_client example code but I noticed that all 4MB PSRAM of my ESP are used by example_connect() . Is this a quirk with this particular example code? Or does esp_http_client actually use all ex...
