ESP32CAM

[mackowiakp]

I have the opportunity to buy greater amount, and very cheaply, ESP32-CAM modules, but without camera modules.
Can ESP Easy be installed on it (via USB-UART converter) and used for simple applications such as controlling a relay and one I2C device?
I tried one and you can install an example sketch on it, which is included in the default Arduino-IDE installation kit for the "AI Thinker ESP32-CAM" board.
If so, what type of board should I use for ESP Easy compilation for such module?

The most important question is the amount of flash present on those boards.
If it has > 4 MB of flash, you may also consider the new "max" builds as they have all plugins and controllers included.
Otherwise it is just the 'standard' selection of ESP32 builds. Since those modules don't have an ethernet port, you can ignore the builds with "ETH" in the name.

It has 4M.
So will try my favorite (so far) 20191208 release. Not ETH support for sure.

Does that rather old release already have a working ESP32 build available? Please pick a more modern release, like 20210223 that has proven to be quite stable.

[mackowiakp]

There is custom_ESP32_4M316

[mackowiakp]

OK. Will try ESP32 20210223

When using such an old version, any support request will result in the suggestion to try a newer version of ESPEasy

[mackowiakp]

Hmmm. I try ready binary ESP_Easy_mega_20210223_custom_ESP32_4M316k.bin and own compilation with Custom.h, but in first case there is no WiFi AP available from ESP in second case, predefined credentials to WiFi HotSpot does not connect to AP.
Any idea?

When flashing using the ESP32 flash tool (the Espressif one), you should select the file with factory in the name, that defines the correct memory partitioning. After that initial load you can then use the OTA feature of ESPEasy to update with the regular .bin file.
When self-compiling, preferably using VSCode and PlatformIO, the upload command from PlatformIO does all the necessary stuff to upload that partitioning and bootloader correctly. And again, after the initial load the OTA update can be used.

THX. Yep. After flashing "factory", Custom.h compiled bin works!

[Ath]

Great, problem solved then

[mackowiakp]

YEP ! THX once more !

I have a problem with rules in this release. Sometimes it save content of edited rule, but in most cases - not.
Is any workaround?

What browser do you use?
Also do you have a password set?
I know there is still an open issue with rules handling if there is a password set.

[mackowiakp]

What browser do you use?

Last version available in my Linux repo that is Firefox 78,10 ESR 64 bit
Will try with Chrome.

Also do you have a password set?

Yes, I have.

[TD-er]

It might be possible the authentication got expired.
I don't know what the default timeout is, nor where the session is kept. We don't explicitly set it.

I do know that switching between tabs/browsers sometimes may log you out on the other one.
It is working a bit funky.

So better keep a copy of your edits in a notepad to be sure.
