Hello friends
After compilation, the firmware file appears in the project folder.the bin that is loaded into the module
Is there a way to download this file without using the PlatformIO programmer?
For example, “flash download tool”
And how and from what address should I ship it? Do I need to split it into parts or do something else with it?
Yes Doc. every MCU have own utility…
If you execute the project task “Advanced → Verbose Upload”, you will see exactly what command PlatformIO uses to upload the firmware to the board. You can then use the same command.
That’s the point, the goal is to upload by third-party means so that other users don’t have to install PlatformIO to easily download the firmware.
How about WebUpdater ?
Simply upload your firmware.bin via webbrowser.
WebUpdater might not work depending on which Raspberry Pi or STM32 he has. I don’t see a specific chip or board even mentioned.
That leave’s Marian’s answer equally vague answer the most correct. Whatever vendor made your board probably has some kind of a tool. Most of them can do any splitting needed, but guesswork isn’t the way to solve this.
You might have missed this post which clearly states that the quastion was about ESP32.

Ah, yes, a post in another thread. Of course. So it seems this has indeed been solved.
As a mod in other groups, I get the power of recognizing regulars that may post several disconnected things in a short burst, but it sure does make reading a backlog of posts trying to help out confusing! Thanx for the clue. There was some other post that I recently read that was bewildering. Maybe if I dug around in the post history of all the participants, I could make sense of them.
Maybe I should just keep moving. 
Thanx!
