Hi,

this is the first time I own such a board. I purchase 1 azdelivery esp32 devKitC esp32-WROOM-32.

I try to programm it with vscode.

To upload a program with the usb cable : is it normla, that I have to press the boot button while uploading ?

2) I try to upload OTA feature. I can upload with usb calbe, but, once it is done, ota doesn't work : it stopp at 8%. I don't know why.

Here is my code :

Here is platformIO.ino (I don't know if it's the right board !)
