Sketch board

Installed (portable and local installations). Make sure you are running the Arduino IDE where you installed the ESP32 add-on.4. A fatal error occurred: “Failed to connect to ESP32: Timed out… Connecting…”When you try to upload a new sketch to your ESP32 and it fails to connect to your board, it means that your ESP32 is not in flashing/uploading mode.Having the right board name and COM por selected, follow these steps:Hold-down the “BOOT” button in your ESP32 boardPress the “Upload” button in the Arduino IDE to upload a new sketch:After you see the “Connecting….” message in your Arduino IDE, release the finger from the “BOOT” button:After that, you should see the “Done uploading” messageThat’s it. Your ESP32 should have the new sketch running. With those boards/with that setup, after uploading a new sketch, press the “ENABLE” button to restart the ESP32 and run the new uploaded sketch.You’ll also have to repeat that button sequence every time you want to upload a new sketch. But if you want to solve this issue once for all without the need to press the BOOT button, follow the suggestions in the next guide:[SOLVED] Failed to connect to ESP32: Timed out waiting for packet headerTo be honest we’re not sure why that happens with the newer boards. We don’t have any ESP32 board with that behavior. We think there might be something different with your specific board or the Arduino IDE fails to send the right command sequence to put the ESP32 automatically in flashing/uploading mode.5. Error compiling WiFiScan sketchIf you try to upload the ESP32 WiFiScan.ino sketch provided in the ESP32 Getting Started guide:And it fails to compile with a similar error message:In function ‘void setup()’:ScanNetworks:52: error: ‘class WiFiClass’ has no member named ‘firmwareVersion’String fv = WiFi.firmwareVersion();It looks like your Arduino IDE is compiling the WiFi library for the Arduino board (instead of using the ESP32 WiFi library).Note: you’ll probably never use any WiFi shield with your Arduino board, right? If you don’t use it, you need to remove that folder/those folders from your Arduino IDE (move it to your desktop, for example).The WiFi library is located, in a similar path:C:\Users\ruisantos\Downloads\arduino-1.8.7-windows\arduino-1.8.7\libraries\WiFiAnd/or at:C:\Users\ruisantos\Documents\Arduino\libraries\libraries\WiFiAfter removing the entire WiFi library folder from one location or both locations, restart your Arduino IDE and try to compile the code again.If you plug your ESP32 board to your computer, but you can’t find the ESP32 Port available in your Arduino IDE
