Connecting Lopy and Arduino

[spnear]

Is there a way to connect an Arduino with LoRa Shield as node with Lopy as LoRa Gateway? Or the Lopy as Node and an Dragino (LG01) as Gateway? I have tried the second case (Lopy as node and Dragino as Gateway) but no get any message at my dragino, i used the the node code from this page https://docs.pycom.io/tutorials/lora/lora-mac-nano-gateway/ (changed to US915 because I'm from Colombia)

Thanks :)
