Cubecell vs ESP32 Lora

Hi to all
I use cubecell as a node , connected to TTn gateway. Example sketch works fine. I use another board Heltec esp32 lora v2 as receiver, same 868 MHz settings, default SF DR etc. It can see another Heltec esp32 lora as transmitter, but not see Cubecell transmit data. Is it some settings missing or what.

Use one node to receive lorawan information from another node?
