Flowcode Support Board

While compiling a flowchart to an ESP32, I need to push the boot button at a certain point.
After "connect" appears in the compiler message screen.

I noticed that it's not clear when to boot the ESP32 (Wroom32) at that stage.
Many times I've lost the opportunity to boot and compile the program to the chip.
It's not clear when during this process I need to push the button.

So if (in the compiler window) there could appear a message when to push, I wouldn't need to keep pushing the button randomly.

Hi MJU20

I've heard of the button but I never have to press it when programming the ESP32 WROOM with FC9.

What hardware do you use?

Hello,

I think the boot should be triggered automatically by the hardware when the communications port is opened but this is hardware dependant and requires some electronics on the host board to connect the RTS/DTR signal to the Boot pin.

Most ESP32 boards seem to come with it fitted but some either may not have the required hardware or there could be a problem with it.

What board are you using? Sorry seen now it's the Wroom32.

I beleive this is the hardware in question on the Lolin32 board.

Hi.
This is regarding this topic
I have a few Wroom boards.
Some need the button pressed to avoid timing out and some don't
I'm not sure why that is the case?
