I purchased some of these V3 HelTec boards to conduct LoraWAN discovery:

https://www.amazon.com/MakerFocus-Development-Bluetooth-0-96inch-Display/dp/B076MSLFC9/ref=sr_1_6?crid=3R2JSY2AFKC1E&keywords=lora+oled&qid=1668810129&sprefix=lora+oled%2Caps%2C106&sr=8-6
Due to version advances of the Arduino IDE and the newer V3 boards, the HELTEC libraries no longer function. The HELTEC Lora devices are decent little boards, but they become largely unusable without current libraries. Numerous posts of “angst” exist regarding the lack of accurate documentation and the outdated libraries. I have made some progress decomposing the libraries and identifying the “pain points.” This scenario presents as a great use case challenge for Random Nerd Tutorials. Thoughts Rui & Sara? Thanks

Hi.
What libraries are you referring to? And which errors do you get?
You can still use the board as a regular ESP32 board, as long as you know the board pinout. You can use the OLED libraries and LoRa libraries. You just need to know the pinout of the board.

Sara

You shared the PDF file in a private response.
Can you share it without being private? So that anyone can benefit from that info?
Thanks.
