Esptool error: link Blynk to an ESP32 Anyone to help me pls?

[blynk_learning]

Hi, I just start using arduino software and I'm currently trying to connect my blynk app to an ESP32 dev module. I've adapted my code to my wifi datas, installed the good libraries... and everything seems to be OK but when I try to upload the code into the card, the following error message appears ! Could anyone help me ? Thanks a lot

google is your friend

I took the last line of the error-message and googled

Google Search

@StefanL38 the problem has nothing to do with Blynk

[StefanL38]

So what do you recommend?

@Juraj Hi, thanks for your help. Do you have any link to the process to follow in order to solve my problem?

[blynk_learning]

@StefanL38 thanks for you help ! I will try to solve the problem with your links

[Juraj]

show us the complete output of esptool

[blynk_learning]

where can I find it ?

[Idahowalker]

It can be found in many places depending upon what it is.

Images of error messages suck.

Include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Did the OP actually setup the IDE to use the ESP32?

you posted only the error, but not the progress of the esptool before the error

@Idahowalker @Juraj here is the whole error message and the whole response to the upload

Do the same as described here

If you get a compiler-error or an upload-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to post …

is your ESP-board really Serial port COM3??
The comport in the Ardiuno-IDE must exactly match with the com-port-number that gets added in the device-manager (windows ) If you use a mac. well another thing specialised for mac how to look up the com-port on a mac. mac-users are really "special"

[blynk_learning]

Ok I'll do the same as described there and I tell you what happen

I tested both on the Mac and on Windows. COM3 is automatically detected as my "ESP32 DEV MODULE port" so I think it's the right one...

Thanks a lot for your help

[StefanL38]

@blynk_learning

COM3 is automatically detected as my "ESP32 DEV MODULE port"

Which Arduino-IDE are you using?

I don't think that the Arduino-IDE is able to automatically detect the right com-port
