ESP32 programming

[WingNut]

Something i've noticed and thought to pass on. I've been working with ESPwroom and compiling to target via the normal manner with micro usb .
Having got so far I needed a case to put the device into so I got on the 3d printer. The slicer program I use is Cura. Slice your design and copy to micro sd card and plug it into the printer. Problem is Cura seems to hang on to the comms resulting in a failed write to device from flowcode. Not a big deal now that I know but had me scratching my head for an hour or two. Close cura and the esp32 programs ok. So even though it uses the thunderbolt connector it can tie up any other com port. It may just be my laptop but something to watch out for if your suddenly getting write errors

I've noticed this too, it seems Cura likes to intermittently talk to any available COM ports which wreaks serious havoc with any data being transferred.

Glad it's not just me this has caught out, think I've also lost hours to this on more then one occasion.
