force reboot if no app received from uart after given timeout

[thierry37_2]

Dear Espressif team

I am working on a custom board with a WROOM module, and esp-idf v4.3.1. I have a question about the upgrade over UART:
- at startup, the esp32 enters in bootloader mode if GPIO0 stays 0 from some time after EN is back to 1.

- from this point in time, the esp32 waits for receiving some software over UART
- from what I can see, it stays in this state forever ?

Is it possible to configure some timeout (for instance 10 seconds, 30 seconds ...) so that the esp32 reboots if nothing is received from the uart ?
Best Regards
Thierry

Just giving another option if they say no.
You could use a device like this to do what you want.

Thanks, good to know, even if this is not an option for me in this project since the board is designed already

I think there should be some software configuration for this, but I could not find easily how to do it ...

Best regards
