It’s you cable. Flashing an ESP32 is trivial. Google it and follow the instructions.
its not my damn cable. I’m using one from an xbox controller that’s good for data. Tried 3 others also for good measure. I imagine its a driver issue - which driver if any did you need to install, and what OS are you installing from? Which browser? As i said, i’ve flashed m5atoms and a bunch of sonoff 8266 fan controllers without problems.
This is an EZsalt 3.0 if that makes a difference.
edit: Tried about 20 more cables. Its not the cable. Can anyone with a EZSalt 3.0 (not 2.0) please confirm that this worked for them, and whether or not you had to hold down the button to put it in flash mode? Also bonus points if you installed any particular driver (i believe you shouldn’t need one if it has a USB controller but i could be wrong)
I also tried from my laptop but it doesn’t appear to have a COM port at all. Bit confused about Windows and COM ports. Tried connecting right to the HA box also but it only ever shows my skyconnect as a valid USB device.
Michael, are you saying its impossible to flash with the 3.0 over USB, regardless of cable? So we’d have to crack open the case to do it?
