I’m on a project with P2P between two RAK812 that work perfectly on Arduino Uno. Now, i want to use Arduino Pro Mini in 3,3V to reduce power consumption, but i’m not able to communicate with the RAK812 module anymore ! Nothing. I guess i have to bypass the 5V to 3,3V UART converter, but i don’t don’t where i have to put my RX-TX signal …
Someone can help me ?
Thank you very much,
