Just got this new board with display and lora functions.
The problem is I can't get it to upload anything.
"A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header"
The only usb modem option I have is bluetooth and nothing else .... could this be my problem
If it is any idea what I should be using ..... I have only ever used and UNO
I have tried holding the buttons in when connecting but made no difference !!!
