Hi

Can you please adapt your program to use Ethernet.h instead of wifi.h and Httpclient.h?

Thanks

I was trying to implement it with
httpClientOTA2.begin(HOST_OTA, 443, "/index.php", root_ca);
But is not possible (i saw you write... doesn't works but soon will be).
Thanks!

Hi,

I followed exactly your great tutorial and tested on two ESP32 boards. Your solutions would really sort out a problem I have as I need to update ESP32 that gets the .bin from my website.
Unfortunately I got this error.
This is the error
Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled
It seems it is trying to write the buffer in restricted memory area and it gets blocked.

It is just carrying on like this forever.

These are my settings

From the search I did maybe there is no final character \n But I'm still looking for a solution

How did you make it work for yourself?

I gave this a try (code exactly as is, just changed wifi and host url) on an ESP32-WROOM32.
After successfully downloading the new application and rebooting, the same download code is running again. Not the new application. I must be missing something here..
any ideas?

Hi! I'd very much appreciate it if you could help me out.

below you can see my serial output;

14:06:51.524 -> ..
14:06:52.075 -> WiFi connected
14:06:52.075 -> IP address:
14:06:52.075 -> 192.168.178.213
14:06:52.075 -> Response: 200
14:06:52.174 -> FW Size: 4294967295
14:06:52.174 -> Updating firmware...
14:06:52.174 -> ..........................................................................................................................this keeps going for a while but eventually stops

I am unsure why it does not pass line 91. I am getting my .bin from a simple nodejsweb server, it does not seem to provide a content-length which is why "FW Size: " prints out the highest number because in reality it's -1. do you think this might be the issue here, and if so what could I do about it?

I have also tried changing the " if(currentLength != totalLength)" statement so it would pass no matter what after a while, so it is possible, only then when it restarts the ESP it will still be running the same code not that of the .bin....

I am using a ESP32 DEVKITV1.

i used this code with this link which i uploaded my firmware file to it
https://drive.google.com/uc?id=1CGPNlpRMR9VKpC6HS3vWJtr4JCS6gB6Q&export=download the esp32 can connect to wifi but the response code is not equal to 200. when i use https header it gives 303 response and when i use http header it gives 301 response.i know that both of them are related to redirections. i tried using this line for automatic redirection but it didn't work client.setFollowRedirects(HTTPC_STRICT_FOLLOW_REDIRECTS);
it gives response -1
