It hasn't been mentioned much for some reason but the recent IDF update has significantly improved connection speeds. It was consistently taking 1100-1300ms to connect to my home WPA2 network a couple weeks ago, but in testing this week I'm consistently getting about 500ms now (often ~400ms). I have...

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition I think you're using AsyncWebServer so your handler might look something like this: AsyncWebServerResponse *response = request->beginResponse(200, "text/plain", "My file contents"); response->addHeader("Content-Disposition...

Isn't this line wrong? For "spiffs.bin", indexOf("spiffs")==0 so it won't be detected as U_SPIFFS type.

Code: Select all

int cmd = (filename.indexOf("spiffs") > 0) ? U_SPIFFS : U_FLASH;

Try

Code: Select all

int cmd = (filename.indexOf("spiffs") > -1) ? U_SPIFFS : U_FLASH;

Arduino is pre-compiled with CONFIG_ULP_COPROC_RESERVE_MEM = 512, meaning that 512 bytes (ie. 128 words) are reserved from 0x50000000 for a ULP program, and anything with the RTC_DATA_ATTR attribute comes just after that (ie. 0x50000200, as you noticed). There is 8K of RTC slow memory available in t...

I wrote a similar comment yesterday but you deleted the post! I see you fixed a couple things (not what mike rightly pointed out though). I think most of this is still relevant: The "one" "two" "three" variables are really confusing and difficult to follow. I think you might even be confusing yourse...

To be clear, is your ULP program ending immediately after it reports the power supply down state? Or does it continue to run while in deep sleep? Are you confident that the problem is that the ULP program isn't running, or is it possible that it's running but there is some other problem (eg. pin not...

Code: Select all

IPAddress IP = (10, 10, 1, 1);

->

Code: Select all

IPAddress IP = IPAddress(10, 10, 1, 1);

Try something like this.

Code: Select all

wifi_country_t myCountry;
if(esp_wifi_get_country(&myCountry) == ESP_OK){
  Serial.print("Country Code: ");
  Serial.println(myCountry.cc);
 }

Why would you go for a 6210 over the 6220? I think it's perfect for ESP32: up to 1 amp in high power mode, and seamlessly switches to Green Operation mode (nominal 8uA but even less than that in my real world experience) when load current drops to less than 1mA (ie. deep sleep). Also slightly better...

I would first address whatever is causing that to take 10-15 seconds with your current setup. That's an extraordinarily long time.

I share your frustration with deep sleep wakeup time though, so you may be as interested as I am in following/trying this: https://github.com/espressif/esp-idf/pull/3304
