Re: Simple WebServer doesn't work

Maybe you need to wait until the wifi is connected before you start the server.

Re: read from i2c failed 80 percent chance, after couple reboot it works

I just got around to doing a production test program. They wanted it done with Arduino IDE because they are familiar with the environment. I find that the I2C fails frequently right after programming and requires up to a couple resets before it works. I never have this problem with the IDF. Looks li...

Re: ESP32 won't connect to home WiFi, but connects to hotspot

The ESP32 only supports 2.4GHz wifi.

Re: Can ESP32 both manage one WebServer and one MQTTClient?

I don't see why not. I've used an MQTT client and an HTTPS client at the same time.

Re: Started validation for ESP-EYE Development Board

I recv'd one as well. Am very interested in wake word detection. There is only one in English... "Hello Lexin", in the ESP_WHO IDF. Unfortunately it takes me saying it a dozen times before it detects.

Re: How to do OTA from unknown local server

Or go easy way and turn off https for esp http client in menuconfig. Not thinking that will do anything. Plus, you can OTA w/ HTTPS and w/o a certificate. Disabling HTTPS won't change the fail checks in esp_https_ota. Maybe you know something I don't, but I'm not seeing this as a workable answer. J...

Re: How to do OTA from unknown local server

Just take out the checks for cert and https in esp_https_ota and you can OTA from HTTP or HTTPS without checking the cert. Just comment out the two return ESP_FAIL lines. Here.... if (!config->cert_pem) { ESP_LOGE(TAG, "Server certificate not found in esp_http_client config"); //return ESP_FAIL; } e...

Re: OTA simple example without certificate check

Seems that config.cert_pem has a random non-null value. Otherwise it would have failed and printed a message on this line in esp_https_ota.... if (!config->cert_pem) { ESP_LOGE(TAG, "Server certificate not found in esp_http_client config"); return ESP_FAIL; } Now, if you set it to NULL, it will fail...

Re: What is a watchdog, why does it need to be feed, what is it fed, and why does it stop my code from running properly?

Is there any effect if we disable the watchdogs ?? I am using upto 10 tasks in my code but giving me an TG1WDT RESET ERROR. So I want to remove this error to prevent esp32 from reset. I want my esp32 live for long time. Could you please explain if any issue by disabling watchdogs? Is the WD resetti...

Re: Start encryption

I'll be needing to do this soon. So I'm particularly interested in this thread. I'm a bit confused about how you can encrypt the firmware in advance to allow OTA, but not have the firmware encrypted again while being written to the flash. Is it possible to specify certain partitions that will be enc...
