E30 Lora problem

Hello, i'm using lora E30 and trying to send message with wemos d1 mini and recieve it also with wemos d1 mini. My problem is i can't get any configuration using exact example. I get next message: No response from device! (Check wiring) 12 So, i checked the wiring, i put independent voltage source for E30. I'm using LoraE220 library, is this an issue? Do i need to change it to LoraE22 series or LoraE32 series? Thank you.
