pet feeder : esp_wroom_02 or esp01_1m ?

[jsapede]

spent many hours today to have it work but seems ok now.

however, whent i make esphome autoconfigutation at first, it always setup an esp01_1m instead of esp_wroom_02 as specified in the config.

I erased and reinstalled all with esp_01_1m instead of esp_wroom_02 and it works (flawlessly ?).

made many try, and probably errors with the first try but never got it working with esp_wroom_02.

Got wifi connections problems like ESP8266EX WiFi Connection Issues ('Probe Request Unsuccessful') and impossible to connect to wifi and impossible to get to fallback, as password was always wrong

It's certainly very weird that it didn't work with esp_wroom_02 config, but that is only configuring the pin labels&functions, and memory available for the esp chip / system-on-module.

esp_01_1m is the generic ESP-8266 variant, with 1MB of spi flash. Luckily, the WROOM-02 package has the same pins, but an integrated 2MB flash chip.

if your actual chip looks like the one in page 6 of the datasheet it should have worked.

If it's different, we need to update the wiki/config with a comment explaining alternatives to try :).

Glad to hear you sorted it out in the end, anyway!

Fortunately got a second feeder AT home
Now configs are good i'll retry with wroom

What's the verdict? Is that a hardware variant you discovered? Comparing chip labels may be helpful.

If a board with a smaller flash works, maybe parts of you flash are just broken? In that case, flash tools with verify steps should point that out.

In any case, if another board config works for more devices, maybe we just need to adapt our config if there's no drawback (with a comment explaining the deviation)

dont know exactly
when i changes to esp01 it worked but maybe this wasnt the only change i made.
reverted back to wroom version on both feeders i have and it works perfectly

So let's consider it resolved, whatever it is/was ;)

If there're new findings just let us know!
