The problem with this card is how to access the subghzspi.
Yesterday I tried to adapt the lorawan code ( GitHub - danak6jq/Seeed-LoRa-E5: LoRaWAN end node built from scratch using CubeMX for WLE5x in the LoRa-E5) to make it an example ping pong. I can compile the code with stm32cubeide, but the two boards cannot communicate.
In the other forum, I saw that a guy is trying to access debug pins, we hope he can do something, however I am continuing to try and search the internet.
The funny thing is that this morning with a Nucleo-32 board, an arduino nano board and 2 lora modules, I was able in a short time to get them to communicate with each other.
