I’m following a RandomNerd tutorial about uploading a PIO program to an ESP32 ‘over the air’ (OTA). I’ve reached the stage where I need to choose the file ‘firmware.bin’ on my computer (iMac with MacOS Big Sur version 11.3 - recently upgraded from Catalina). Although VSC Explorer shows all the project files as expected (including firmware.bin) I can’t find firmware.bin anywhere on my computer, so can’t select the file to make OTA work.
In my ‘PlatformIO’ directory under ‘Documents’ on the iMac I have a PROJECTS sub-directory, which has a sub-directory for my individual projects, each of which has sub-directories called ‘include’, ‘lib’, ‘src’ and ‘test’, with a file called platformio.ini. No sign of anything called firmware.bin. The Mac ‘Finder’ facility doesn’t seem to reveal any clues.
Any tips on where I’m going wrong would be appreciated.
