Using serial-flasher wasn't really an option aa I don't like using libraries and it would have made integrating all the other things the code does much more difficult than if I just wrote the serial protocol from scratch. Plus I had already made it so far there was no way I was going to lose all tha...

Well if I configure spi, it does accept the command but no other commands work after that. I used the values in the serial-flasher source code. It appears they have the ID set to 0. I've tried that as well as the actual chip ID and get the same results. Nothing works after it takes that command but ...

No, i wasn't really sure what values to send but I guess that would make sense, huh?

https://github.com/espressif/esptool/wiki/Serial-Protocol will give you what you need to know, but beware that it's a little confusing and not all that straightforward. You'll also need to look at the serial flasher source code for some things, especially to see how they do the CRC because it's not ...

I'm able to erase and flash a 4Mb ESP32 over UART from another mcu using the serial protocol found here https://github.com/espressif/esptool/wiki/Serial-Protocol. The problem is, anything written past 2Mb with command 0x03 isn't actually written. It responds that it's been written, but if you read t...

I want to use the ESP32s in it's default AT command mode, but I need a pin to go high or low when a bluetooth connection is made, e.g. an led light up when connected. I want the firmware to work as intended but I really need a status pin and preferably have it do this by default, even after a reset....
