ESP32 gets very hot and WebUI crashes when opening "Options"

[Sthopeless]

Hello there,

Yesterday after discovering PedalinoMini I flashed immediately into my ESP32, I believe I have followed all instructions given on the README.md (Build, Upload, Upload Filesystem Image) and I only changed the upload_port in PLatformio.ini to match my MCU.

After all is flashed I see the device reboot and shortly after I can see and connect to the AP and open the WebUI at http://192.168.4.1 but as soon I open Options tab the ESP32 crashes and reboots I also noticed with PedalinoMini the ESP32 keeps warming up pretty heavily almost too hot to touch sometimes.

Any idea what I am doing wrong?

Here's the serial log:

Seems to be fixed by uploading first v2.0.0 then upgraded after connecting to my WiFi and it seems to be working. Also all the heat seems to have disappeared and feels normal again.

V1.0.0 didn't compile with some problems with one of the libraries V2.2.1 still gave the same problems (Options tab on WebUI didn't open and ESP32 crashed and rebooted and it was extremely hot)

[alf45tar]

I never seen an ESP32 going hot apart when it is charging an 18650 battery

[alf45tar]

I always suggest to use the latest version. Did you try 2.2.2?

[Sthopeless]

@alf45tar yes sorry forget to mention, my initial test was with the latest version! I also tried more than once. All USB powered with only a I2C Display connect.

It seems to be working alright since I upgraded from v2.0.0, I can open Options tab and the heat seems normal for a running ESP32.

My board was running Tasmota firmware for very long time and stable so I assume it's is not faulty. I have ordered few more devkit's v1 and when they arrive I see if same happens.

I decided to Erase Flash and try again with v2.2.2 (latest) Problem persisted, Options tab did not open and the ESP32 heats up like crazy. I then decided to turn off PiHole and 🤣🤣🤣.... it worked!

So the problem was on my side, still not sure why it heats up like crazy awhile PiHole is on 😄 but after WiFi is configured etc it all goes away and seems to be working OK...

It can be closed but I have few more questions rather do it here then open another issue, if that's alright.

I am trying to configure the firmware, WiFi connection, login, theme and such.

In Config.h line 558 load_factory_default I changed host, WiFi ssid & password, AP ssid & password, http login & password and theme. After erasing and reflashing it connected automatically to my WiFi but all the other options were still default.

After a few more digging I found also in Config.h file around line 714 the void eeprom_update_... lines and after configure them to use the load_factory_default values seems to have fixed.

Wouldn't make sense to be like this by default?

Example at: https://github.com/alf45tar/PedalinoMini/blob/master/src/Config.h#L758

void eeprom_update_login_credentials(String username = "admin", String password = getChipId())

Replace with:

void eeprom_update_login_credentials(String username = httpUsername, String password = httpPassword)

Lastly, my Bluetooth device name is the getChipId() is it possible to change it. if yes where? Nvm, found how to change the Bluetooth device name at line 24 in BLEMidiOut.h

TIA
