Unable to build a second ESP32 Radio

[Fabri54]

Hi, it's with a lot of shame that I'm writing this post. I've built a first ESP32 Radio V2, boxed it and it is now playing on the background while I'm typing. It has been built copying the prototype breadboard into a more structured and clean one. IR, Rotary, SD (Red TFT) are all working and I simply transplanted the ESP32 - WROOM - 32 from the protoboard to the final one. Actually I have used a slightly better audio amp and, with a proper single power supply (9V/3A + 7805 to provide 5V to ESP32), I didn't even need the decoupling audio transformers to get a more than decent audio. However the point here is that I'm now playing with the protoboard (not a single wire has been changed) but I cannot get the ESP32 Radio working anymore. I've tried two ESP32 modules. I've erased all the flash with the esptool.py. I've written the content of the Data folder into the SPIFFS and I've checked that the files are there and read the defaultprefs.txt. It contains exactly what is needed and it's a copy of the one which is running on the working model but, whatever I do I get the following output on the serial monitor (using Arduino IDE 1.8.20)

It's driving me mad. Any suggestion where to look for the cause of this unexpected behaviour? Many thanks

The ESP32 Radio now works but I had to connect to its AP and insert the entire content of the "defaultprefs.txt" file with a copy and paste operation in the Config page of the web server. Actually there was no configuration data with the exception of the first six lines. I do not understand this behaviour. Have I done something wrong erasing the whole flash with the esptool.py ? When I write the content of the data folder to the SPIFFS the operation ends well and, as written, I can then read the list of files inside the SPIFFS as well as read what is inside each file. The module has the following configuration " ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 926100". Please help to understand what I'm doing wrong

You followed the correct procedure. There should be a button on the config page to load the defaultprefs.txt file directly. There is also an editable default network definition in config,h to directly connect in STA mode, The pins however must be configured in the config page.

[Fabri54]

Thank you but I must be missing something. The defaultprefs.txt file is first written into the SPIFFS (it is there, I can read it) then when I load and run the ESP32Radio.ino I expect the program to read the txt file and use it at boot , while when I look at Config using the web access to ESP32-Radio AP it is practically empty. Why?

Here below is the defaultprefs.txt file as it is written into the SPIFFS using Arduino IDE. In addition if in Config.h I insert into #define FIXEDWIFI "MYWIFI/password" one of my wifi networks, at boot it doesn't connect to it and reverts to ESP32-Radio

I don't want to waste your time as, at the end of the day, I have two working ESP32-radio, the official one inside a wooden case and the prototype, but I'd really understand If I'm doing something wrong and, of course, what. Thank you and have a nice weekend

[Edzelf]

No, the defaultprevs.txt is not read at start-up. Only used for filling the config page on a button click.

[Fabri54]

OK, eventually I understand. Thank you again. One last thing, if you are interested I can provide the schematic of the power supply, the picture and the link of the power amp I'm using and that didn't require me to insert the two audio transformers to avoid the digital noise into the audio
