UFO failed

[sygrosjean]

I have my UFO freeze : only one white light is switch on (see in attached file)

I tried to reset but it doesn’t work and wifi isn’t accessible.

Can you help me ?

Is there any reaction if you press the button? (guess not) What happened before the freeze. Did you update/program the UFO?

[sygrosjean]

Hello Helmut, no reaction when i press button and before the freeze nothing like update/upgrade UFO was associated with dynatrace.

This means it showed some colors and suddenly it just showed the white dot, correct? So if a reset (unplug) doesn't solve the problem it looks like the processor is not starting up at all. You could try to re-flash it (see https://github.com/Dynatrace/ufo-esp32/issues/26 for instructions) but I am afraid that something might be broken...

Rebooting...

[helmut-s]

ok - so erasing and re-programming the flash might help (but I have no idea what happened) - please have a look at the linked issue (https://github.com/Dynatrace/ufo-esp32/issues/26)

When i press reset i have "rst:0x10 (RTCWDT_RTC_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2)) waiting for download"

But i can't have access on console I installed "flash_download_tools_v3.6.8" but Com is failed with this tool. With putty communication is OK
