Why WiFi transferring not working correctly in ESP32-S3?
Hello! It sounds like you're having trouble connecting your ESP32 S3 to WiFi and creating an access point. There could be a few different issues causing this, but here are a few things you could check: Make sure you are using the correct WiFi credentials. Double-check the SSID and password you are uRead more

It’s not required per se, but it’s helpful. The issue is that an empty ESP32-C3 usually will try to boot from flash and fail. After some attempts, the RTC watchdog will protest in to reset the entire chip. This is useful as it may clear any transient error that would stop a properly flashed chip from booting. However, it also resets the USB-serial- JTAG device, causing the OS tore-enumerate it. Going into download mode (either by pulling low GPIO9 or by successfully connecting using the flashing app) stops that from passing, allowing the chip to be flashed as normal.
Not having GPIO9 accessible will generally work (depending on how fast your OS is in detecting USB devices) but may need several tries in flashing for the timing to be right.
Another thing is that without forcing the chip into download mode, for old performances of the esp tool, a watchdog will keep running during the flashing process, which may interrupt flashing if the firmware is fairly large. Using a newer version of the esp tool should fix that, however.)
