B4R Question SOLVED A way to flash a sketch without IDE in a ESP32 S3.

[tigrot]

Hi everybody!
I have now a working sketch for ESP32 S3, I want to distribute binaries to my customer, not sources.
So how can I allow my customer to flash his devices? I have found no simple and practical solution to do this task. He will probably flash 10 or more devices at a time.
Does anybody have a solution?

Thank you very much!

If you have no other choice than letting the client flash then, I guess all you can do is maybe create a B4J "intaller" script type of app so that the client can run it on a computer, plug the esp usb-c port and flash it

Why not flashing the first time by adding also OTA update for the next times?

This is a logger. The cpu starts every time a contact is closed. The log is generated on a IIS web server. The cpu goes to deep sleep after this task. However thank you!

Solved, there is an Android app on Google store. Stand alone.

Hi Cableguy the name of the app is "ESP32_flash" in Play Store. I have not tried it, I have to learn something more about Esp32, like memory map, the need to include bootloader and whatever can help. Using Arduino Ide I can flash the device, but this is too much automatic. I'm looking for the protocol to load my app to esp32.
There is a online utility too. https://esptool.spacehuhn.com/
Have a nice week.
