#94444 Hi
I want to compile my project on a PC exporting the compiled binary, move this .bin file to a distant Raspberry Pi on another LAN over VNC and finally upload that file to a Wemos D1 Mini that is connected over /dev/ttyUSB0.

Can someone put me on the right track for that last step?
I find tons of confusing ways to upload on an ESP32, many obsolete, many for ESP modules without USB.

What is the current way to do it from a .bin file over /dev/ttyUSB0 on a Raspberry Pi?

Thank you for your advice.

#94589 OK i am supposed to use

So my command would have been something like:

Code: Select allpython3 -p /dev/ttyUSB0 write_flash 0x0000 BasicOTA-GW-FM-7390.ino.d1_mini.bin

The answer is:
Code: Select v3.3
Serial port /dev/ttyUSB0
Detecting chip type... Unsupported detection protocol, switching and trying again...

Hard resetting via RTS pin...

which looks apparently fine.
But i uploaded the example code for OTA (with my credentials) and it does not seem to show up in the Arduino IDE.

Is the offset 0x0000 the right one?
I cound'nt find any indication of what this offset code should be.
