In secondo luogo è stato aggiornato anche il [firmware](https://github.com/arduino/uno-r4-wifi-usb-bridge/tree/a634856e5467022bc7587e7c8a856811255ea890) che è caricato sul ESP32 e che fa da tramite tra ESP ed il Renesas di Arduiino UNO R4 WIFI ... la precedente versione era 0.3.0 ora si è passati alla **0.4.1**. Per aggiornare il firmware la cosa migliore è seguire quanto è spiegato [QUI](https://support.arduino.cc/hc/en-us/articles/9670986058780-Update-the-connectivity-module-firmware-on-UNO-R4-WiFi) ... a volte va bene e a volte va male, nel qual caso, la cosa migliore è effettuare l'operazione descritta a fondo pagina "_Run espflash directly_" facendo il ponticello e caricando direttamente il firmware. Ripeto, spesso va bene il semplice aggiornamento via USB ed l'apposito programmino, se va male ... passare alla soluzione più drastica 😁 In ogni caso, **dopo aver aggiornato** il firmware è **OBBLIGATORIO** togliere alimentazione (_staccare la USB_) e poi ridarla, altrimenti non si può fare nulla. Buon lavoro, Guglielmo ---

Nella sezione Inglese sono state date delle istruzioni dettagliate per effettuare l'aggiornamento del firmware nella UNO R4 WiFi ... le riporto, tradotte, qui di seguito: * * * 1. Scollegare il cavo USB della scheda **UNO R4 WiFi** dal computer. 2. Utilizzare un ponticello per collegare questi due pin ("DOWNLOAD" e "GND") sul connettore maschio 2x3 che si trova vicino alla presa USB sulla scheda **UNO R4 WiFi** : ![labeled header pins](https://europe1.discourse-cdn.com/arduino/original/4X/9/9/0/990ded4eeaec5052b928f7c6261f380ee6ad152f.jpeg) > **📷** > > [Arduino](https://github.com/arduino/docs-content/blob/main/content/hardware/02.hero/boards/uno-r4-wifi/tutorials/esp32-upload/assets/esp32-data-pins.png) - [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/) (cropped) 3. Collegare la scheda **UNO R4 WiFi** al computer con un cavo USB. 4. Aprire la pagina di rilascio dell'ultima versione del firmware nel tuo browser web: [https://github.com/arduino/uno-r4-wifi-usb-bridge/releases/latest](https://github.com/arduino/uno-r4-wifi-usb-bridge/releases/latest) 5. [Estrarre](https://support.microsoft.com/windows/zip-and-unzip-files-f6dde0a7-0fec-8294-e1d3-703ed85e7ebc#:~:text=To%20unzip%20files,-Open%20File%20Explorer) il file che è stato scaricato. 6. Avviare [Windows " **File Explorer**"](https://support.microsoft.com/windows/find-and-open-file-explorer-ef370130-1cca-9dc5-e0df-2f7416fe1cb1). 7. Apri la cartella `unor4wifi-update-windows` creata quando si è estratto il file `unor4wifi-update-windows.zip` scaricato nel passaggio precedente delle istruzioni. 8. Nell'elenco delle cartelle `unor4wifi-update-windows`, tenere premuto il tasto **Shift** mentre si fa clic con il pulsante destro del mouse. 9. Dal menu contestuale, fare clic su " **Open PowerShell window here**". Ora si aprirà Windows [**PowerShell**](https://learn.microsoft.com/powershell/scripting/windows-powershell/starting-windows-powershell). 10. Digitare il seguente comando nel prompt dei comandi della finestra **PowerShell** di Windows: ```plaintext bin\espflash write-bin -b 115200 0x0 (Get-Item .\firmware\UNOR4-WIFI-S3-*.bin).FullName ``` ... inserendo il corretto nome del file .bin. 11. Premere il tasto **Invio**. 12. La finestra **PowerShell** potrebbe ora mostrare un elenco delle porte seriali presenti sul computer. Per esempio: ```plaintext Start flashing firmware [2023-07-11T06:39:09Z INFO] Detected 2 serial ports [2023-07-11T06:39:09Z INFO] Ports which match a known common dev board are highlighted [2023-07-11T06:39:09Z INFO] Please select a port ❯ COM1 COM42- USB Serial Device (COM42) ... ``` In tal caso, utilizzare il tasto **↓** sulla tastiera per selezionare la porta della scheda **UNO R4 WiFi** dall'elenco, quindi premi il tasto _Enter_. 13. La finestra del terminale ora mostrerà il seguente messaggio: ```plaintext ? Remember this serial port for future use? (y/n) › ``` Premere il tasto _N_ sulla tastiera. 14. Ora dovrebbe iniziare il processo di flashing. Attendere che finisca, come indicato dall'output simile a questo: ```plaintext Chip type: esp32s3 (revision v0.1) Crystal frequency: 40MHz Flash size: 8MB Features: WiFi, BLE MAC address: dc:54:75:c4:c6:54 [00:00:15] [========================================] 826/826 0x0 ``` 1. Scollegare il cavo USB della scheda **UNO R4 WiFi** dal computer. ❗ **È essenziale eseguire questo passaggio**. 2. Scollegare il ponticello aggiunto al passaggio (2) delle istruzioni. 3. Collegare nuovamente la scheda **UNO R4 WiFi** al computer con il cavo USB. Ora la scheda dovrebbe essere nuovamente riconosciuta correttamente nell'IDE di Arduino. * * * Guglielmo ---

Buongiorno a tutti volevo solo far notare a chi, come mi è successo, sta impazzendo con il PC che non vede la Uno R4 wifi. Acquistata nuova originale con il suo cavo USB non ne voleva sapere di farsi vedere dal PC. Cambiato cavo e tutto si è risolto. Buona domenica. ---

@maurizio53: Se segui un po' le varie discussioni qui sul forum ti accorgi che, in caso di problemi, abbiamo sempre detto e ripetuto un'infinità di volte di controllare **COME PRIMA COSA** il cavo USB. Ci sono in giro cavi economici che portano solo i fili dell'alimentazione, ma non dei dati ... sono tipicamente quelli per la ricarica dei cellulari. Questi, ovviamente, NON vanno bene, alimentano la scheda, ma non permettono il colloquio. Poi ci sono anche quelli i cui fili, all'interno, si spezzano, ed anche questi, ovviamente, non possono andare. Insomma, il primo anello debole è il cavo ed è il primo che occorre controllare 🙄 Guglielmo ---

E' stato rilasciato il firmware **v0.5.2** per il modulo ESP32 che si trova su Arduino UNO R4 WiFi. Dalla versione 0.5.x è stata finalmente introdotta la possibilità di fare il "ping", la possibilità, senza altre librerie, di recuperare da server NTP la data/ora UTC ed altre piccole correzioni. La pagina del firmware è [QUESTA](https://github.com/arduino/uno-r4-wifi-usb-bridge) e l'ultima release, come sempre, si trova sulla destra.

... per inciso, la nuova versione del "_core_" per Arduino UNO R4 (_la 1.3.2_) include esempi che sono eseguibili, sulla "UNO R4 WiFi", **SOLO** se si aggiorna il firmware alla versione 0.5.x: ![Screenshot 2025-02-20 at 17.31.58](https://europe1.discourse-cdn.com/arduino/original/4X/0/c/6/0c621add0ef0844a26f4b00129dc63bd745e6f70.jpeg) ... WiFiPing e WiFiTime, difatti, richiedono entrambi l'ultima versione del firmware del modulo ESP32. Guglielmo ---

Solo per informazione ... è stato rilasciato il [firmware 0.6.0](https://github.com/arduino/uno-r4-wifi-usb-bridge/releases/tag/0.6.0) da caricare sul ESP32 presente su **Arduino UNO R4 WiFi** con la solita procedura già descritta in precedenza. Guglielmo ---

L'aggiornamento del firmware ESP32 su **Arduino UNO R4 WiFi** e possibile direttamente dal IDE 2.3.6 con l'apposita funzione ... si collega la scheda, si seleziona che si vuole fare l'aggiornamento del FW, ecc. ecc. (_si raccomanda di verificare che il monitor seriale sia CHIUSO o l'aggiornamento non funziona_)... ... sulla mia prima R4 WiFi la procedura ha funzionato senza intoppi, sulla seconda ... si è bloccata lasciandomi una scheda inutilizzabile 🫤 Ho allora usato la procedura classica, con il ponticello, descritta al [post #6](https://forum.arduino.cc/t/arduino-uno-r4-aggiornamenti/1229040/6) e ... tutto è andato bene restituendomi una R4 WiFi aggiornata e funzionate 😁 Guglielmo ---
