Hello all,

I'm working on ESP32-WROOM-32E.

I made a connection to a wifi but I want to change the hostname but it doesn't work.

I don't understand from when the issue come.

Please find below the code
#include <Arduino.h> //Basique ESP32
#include <WiFi.h> //Wifi ??


const char* ssid = "Bbox ...

I block everything except this function.
I also end server (server.end()) to test if there is something coming from this side.

I change buffer to 4096 and add a delay(1) between read and write but I still have the same problem

Hello,

I try several thinks but can't resolve my issue :(

I just see that about 15 seconds, the ESP32 block on
client->write(";",1);
or
client->readBytes(..)

Even if I test client available & connected and http connected just before.

Do you know where the issue is coming ?

Thanks for your ...

Hi Techgraphix,

could you be more explicit in how you reset watchdog ?

Bonjour,

I tried to download file from a server, it works perfectly for file until around 30ko but when I try for more bigger file (around 1000ko), system crash.

Hello ESP-SPRITE,

my ESP32 board is a ESP32-WROOM-32E-N8

I have several IC working well with this esp32, but IC with the new program have this issue.

If I removed ESP32 from the IC and sold a new one with an old program, everything works fine.

Hello,

More information about this issue.

I find that if the flash upload in QOUT mode ESP32 WROOM works perfectly. If I reupload the program with DIO, reset loop occur again.

I've got several board with this issue.

Anyone have an idea of what happen ?

Thanks for your help,
Antonin
