    It may be with me that it's so long because the weatherman and calendar are interfering at the start - I'll check by knocking out some of the code.
    This is what it looks like before it connects and outputs audio, it jerks the syncword a few more times:

    @MAJSTER XXL I haven't noticed any extended connection time. I have a 600ms delay on startup to get the ESP32 to initialise the serial correctly after a full power-up (after a reset there is no problem) and that's probably the only noticeable delay.

    The bitrate estimation for FLAC is for stations that don't have a fixed bitrate - then you have to calculate it and average it out. If this annoys you then you can in my audio info throw in "audio.getBitRate()" and there you have the first bitrate read immediately. Stations which have the value permanently entered on the IceCast server (e.g. smoothjazz.com.pl) give it immediately. In my case the option "audio.getBitRate()" is used by the function displaying the buffer. In general, quite a few stations broadcasting FLAC streams do not "give a damn" about the correctness of this data on the server

    Important note:
    delete the files in the sketch folder, especially if you are swapping TCP libraries or the Audio library. Arduino is "dumb" and if it doesn't notice the change it won't compile the library in question. It is better to "force" them to do this manually.

    >>21805935 Both radios are great. Don't take this as me making excuses, because far from it. I praise both projects. But if I may interject, easier and simpler to use is @robgold's radio. Plus it has control and station replenishment from a smartphone. It also has, seemingly unimportant and yet, a Power ON/Off button. In addition, it is quicker, my feeling, to get up and log on to WiFi . The radio @robgold will be happy to adapt to the car. Android does not have such cumulative stations. Wife has already ordered @robgold radio for the kitchen so she doesn't fiddle around on the smartphone. The terrestrial stations need a stick. The coverage in the block is what it is. If I may make a suggestion, on @Majster XXL radio I would disable bytes like name or temperature, add buttons to start them on demand, same with RSS, then they don't start from the beginning. And POWER ON/OFF. That's just me dreaming. Don't take this the wrong way. You are both doing a good job. You have your concepts, stick to that. Regards.

    Hello, I'm currently in a dilemma choosing speakers for my kitchen radio. I'd like some standard speakers on Aliexpress, small rectangular ones, but the cheap ones are a pipsqueak, no bass, no farting when you turn up the volume

    Two small speakers on a carpet, one square and one rectangular Two small speakers: one round Bose speaker and one rectangular speaker with wires.

    This plays nice but where to buy one of these because a mate offered to make me an enclosure for the 3D and I wanted fairly universal speakers.

    The ones above play sensational for such tiny things when you lock it in the box even the quality is there.

    Do you have any cool speakers tested from aliexpress ?

    My rectangular one has a 2.8mm side, so it's perfect
    And the square one is 4mm so it's ok too.

    Greetings....

    MAJSTER Nice change with remembering the last song now I won't have to search manually anymore.
    I would have one more request to a colleague that without a router (when there is no Internet - at my phone hot spot) it is possible to start the MP3 player for example with a button, it would already be beautiful ;)

    Best regards ....

    This functionality is available in the radio menu - if you assign yourself the appropriate remote control button to activate this menu, you can disable each of these items individually.

    Hello again. I am asking for your advice as the radio, by some miracle, fired up on the first connection, for which I thank you, as your good advice helped. At the moment the radio is playing without encoders and display, controlled via the web site, but I also have a small problem. Namely, I have to have the PCM5102 DAC connected with a cable to the SCK pin, with this cable hanging loosely on the other side. Without this cable connected to the SCK output, nothing can be heard. Any suggestions.

    >>21806889 Yes it is OK. Only thing is, does it turn off after downloading data, or does it turn off downloading? That is, free link for the rest at start. But it's still OK. I play on it all the time, the test is good. What I wrote was just about a little grinding, not necessary.

    >>21806939 Which version of the radio are you putting together ?
    I ask because I have also seen your posts on yoRadio Poland. You must be aware that the Project described here is not based on yoRadio. It is a completely different design.

    Hello, greetings. Has anyone converted these radios to lcd1602 or lcd2004 displays? Maybe some gotchas checked? I would be grateful.

    No, because it wouldn't make sense.

    Why? In most cases the station name on one line and the song name on the other is enough, for a 2x20 LCD there will still be room for other data when scrolling through a section of the line. What more do you need?

    Yoradio supports these displays. You can always play around, but the project will lose a lot of functionality. Maybe one day.

    >>21806592 I have 5 pieces ordered from JLCPCB. If not in a hurry 3 will be over stock. But that is only in about 2 weeks because it goes Global Standard Direct Line . The description said about 16 days.

    Something like this pops up sometimes. I've uploaded it again, but it still pops up sometimes. I don't know how to fix it. The radio works fine. Only on mp3. It is in the place of "YEAR:".

    @kula350 check first by removing spaces, especially before the file type extension, because in general you shouldn't use spaces before a full stop with an extension, I would never even think of doing that. Also there's probably a mess in the id3 metadata of the audio file, show a screen shot from some editor or a preview of the id3 content of that file.

    >>21810916 You know what I'm thinking now, isn't it from the power grid. They've been fixing something for a few days now. Maybe some weird pins are flying through the grid. It's been gone this afternoon. I'll keep watching. If anything, I'll let you know. Thanks. Regards.

    No pins after the net. The standard does not allow spaces before full stops. The fact that windows can read such creations is only for the benefit of the user. But then such errors are made.
    Correct the name as @MAJSTER XXL writes and the problem disappears.

    >>21811120 I have removed the spaces. As you wrote. Today it was bushing on the subtitle "I am playing a File" on the letters "Odt". After switching to another file, it is ok. After switching back to the one it was bushing on, it is ok. Then everything works. In a while, it's on another one again. I plugged in the lab power supply and it also pops up. This is something transient. But it's such a small flaw, which doesn't bother me in total, because when it switches to the other one by itself after playback the file is normal. I need to check the card as it's not new. Cool. We'll get through it. Now as I'm typing the same error I sent in the picture has popped up and interrupted playback, as if it's not reading from the card. I'll check the card, or swap to another card and test. If nothing happens with others, then maybe something is wrong with my parts. They are going from chinolink new to the other one. We will check.

    Are you sure this is an IL9488 panel? There are no markings on it at all. There is an IPS sticker only. Maybe someone knows what kind of display it is, because I ordered ILI9488 3.5 inch 480x320.

    I have a Waveshare ESP32-S3-DEV-KIT-N32R15 board.

    I have connected like this:
    VCC -> 3V3
    GND -> GND
    CS -> GPIO5
    RESET -> not connected
    DC/RS -> GPIO4
    SDI(MOSI) -> GPIO13
    SCK => GPIO14
    LED => 3V3
    SDO(MISO) => GPIO12
    And I continue to see darkness on it. Anyone had any contact with it ?

    I have the same one is ili9488 only that the IPS version. The connection is the same as a normal TFT, so it must work. Connect the reset to the RESET pin on the esp32s3.

Topic summary

The discussion centers on the development of an internet radio and audio file player based on the ESP32-S3-WROOM-1 module, featuring a custom-designed prototype PCB with OLED display and user controls including rotary encoders and buttons. Key challenges addressed include pin spacing discrepancies in the ESP32-S3 module footprint, integration of Wi-Fi connectivity with dynamic station list updates, and handling of Polish character encoding on the OLED display. The project uses Arduino IDE (version 2.3.2) with ESP-IDF support and requires enabling PSRAM. Audio playback supports MP3, AAC, and FLAC streams, with the ESP32-audioI2S library recommended over the incompatible Audio library. Users reported issues with SPI MISO pin assignment causing bootloader conflicts, resolved by reassigning MISO to pin 35. The project incorporates WiFiManager for network configuration, EEPROM and SD card storage for saving last played station and settings, and includes plans for tone control via an external KA2107 equalizer and a CS8673 amplifier module. Problems with encoder input stability and memory limitations for Bluetooth A2DP on ESP32-S3 were noted. The community suggested alternatives like KaRadio and ESP32-MiniWebRadio projects. Debugging tips include serial terminal logs for HTTP errors and flash memory erasure to resolve boot loops. The project is open-source on GitHub, encouraging forks and modifications. Additional features under development include browser-based updates, directory navigation, and potential audio recording to SD card.
