Hello, thank you for your answer. The TTGO card is detected. I uploaded your code and it works great. I don't have a restart with your code.

However, with the code on this site: https://randomnerdtutorials.com/ttgo-lora32-sx1276-arduino-ide/, the card restarts all the time. Just like with my code.
