Develop custom firmware with Arduino IDE or on Lora E5 mini

Hello I would like to use the Arduino framework to code directly on the Lora E5.

I tried to add the seeedstudio board manager url but I don’t find the E5 in the list.

I tried also with on vs code. It seems that arduino is not supported but only “cmsis”, “stm32cube”, “zephyr” (see : Add support for LoRa E5 Dev Board by nobodywasishere · Pull Request #624 · platformio/platform-ststm32 · GitHub)

Do you have some advices to make it work ?

Thanks in advance

As far as I know you have to use the STM32cube environment to program it for now :frowning:
