LoRa eByte SX1276 E32 868T30D to 868T30D communication issue

I could not communicate the two lora with the EBYTE SX1276 E32 868T30D. I have tried all of the resources below. I tried Arduino Mega and Arduino Uno separately. What should I consider? What am I missing?

There is communication with Arduino with 433Mhz lora. No problem.

I solved it. Boltage should go with 3.3 V to LORA.
