Software Support for the new Wifi Kit 32 (V3) is horrible #96

Factory delivered program is non-existent. Examples for OLED drivers reference SDA_OLED which is not defined anywhere in any files in the repository. esp-idf support is non-existent. The software support for these devices is incredibly confusing and disorganized.

Wow. It sounds like having a wiki to organize this incoming issues may make sense? I saw the aliexpress pages warn that it's only for the weary at the moment. And, that it only supports esp-idf for now? I've got a bunch coming via fedex and plan to plow through issues.

Wow, have to agree about the lack of documentation. It's woeful.

indeed, there is a complete lack of information, which can make development extremely difficult and slow for beginners (I am one of those people). I recently bought the new V3 boards but I noticed that these new boards are not in platformIo nor in esp-idf, so I tried to fork platformIo and esp-idf which I used to develop

I am disappointed with this board too - bought 4 of them without knowing what I was getting into. Any material I could find on it was posted within the last few days. I am a beginner to this stuff too. To even get platformio to build and upload was a goose chase, needing to point the platform to a farked version of arduinoespressif32 guided by the conversation I found here https://community.platformio.org/t/heltec-board-setup-libraries-esp32-s3-wifi-kit-32-v3-w-oled-ssd1306/31316 Anyway, I finally found the right pins by tracking them down thru the installed library from the fork https://github.com/espressif/arduino-esp32/blob/d342739308436e13e56a5c4d3fe597076a1d36b3/variants/heltec_wifi_kit_32_v3/pins_arduino.h#L71-L73

RST_OLED = 21
SCL_OLED = 18
SDA_OLED = 17

Hope this is useful to others, because I can't find this anywhere else on the internet at the moment. The datasheet for wifi_kit_32_v3 is also complete canine-doodoo and only mentions the reset pin. Thank God these pins finally work for my v3.

For the V3 we need to new versions of the board and library. Close the Arduino IDE. Delete the old version, which will be in a directory such as ~/.arduino15/packages/Heltec-esp32/hardware/esp32/0.0.5

Open the Arudino IDE, then select File > Preferences and set this URL to get version 0.0.7 of the library: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.7/package_heltec_esp32_index.json

Note that version 0.0.5 won't work. You need 0.0.7 or higher.

Go to boards manager. Update Heltec ESP32 to 0.0.7 or higher.

Click Tools > Board and select the V3 version of your board.

Now ESP32 examples should work.

Worst of all is the complete lack of interaction with Heltec. Broken links, incomplete or wrong documentation, etc. This is not good customer support Heltec!
