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 Numerous posts of “angst” exist regarding the lack of accurate documentation and the outdated libraries.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

The issue with MakerFocus ESP32 LoRa 32 (V3), ESP32 Dev Board W I F I Bluetooth LoRa Dual Core 240MHz CP2102 with 0.96inch OLED Display Arduino IDE and Library support has largely been resolved over on the HELTEC community forum. Resolving the issues was a multi-faceted exercise. A synopsis will be posted directly to the RNT forum.

Thanks for sharing that info.
I couldn’t access the link you shared. Can you check if it is correct?

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.

Hi Sara- I marked the prior PDF as private as I was testing a number of hypotheses and did not want to “confuse” the RNT community with all of the raw errors. The link to the HELTEC thread probably did not work due to the HELTEC forum requiring authentication of users. I deleted the errant link. As mentioned in my most recent post, I will create a summary covering resolution of some identified V3 IDE (board & library) support issues and post it to the RNT community. Relevant portions of the PDF will be incorporated into the summary post. Thanks!
