Lora esp32 V2 not transmit lora data 433MHz

#1

Hello,
I am trying to send with Heltec LORA wifi kit V2 to another lora module (SX1278) that connected to arduino but no success.

I make the same configuration of LORA but not see anything in the receiver.

But if working without the heltec lora transmitter the receiver is working well.

You can experiment with two heltec products.

Another option? I have only 1 heltec device
