Hi, does anyone have idea about this error during compiling?

This library does not support V3.

#3

thanks, what is the correct library I should compile on my v3? the Wi-Fi serial kit?

I have basically the same problem . The https://github.com/Baptou88/arduino-esp32.git repo doesnt include LoraWan102 so no lora support (other aspects relating to esp32S3 etc appear to work)

The HELTEC WiFi-serial kit is broken wrt git clone fails due to a littleFS problem (https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/issues/153) which somehow others (non platformio folks?) are still gettting around 10 months later…

platform_packages = framework-arduinoespressif32@https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series

so platformio can’t start the build.

All pretty broken…not sure Heltec is actually supporting anything outside of ArduinoIDE.
