Heltec lora esp32 v2 connect to RAK7268V2

hi,
I am very new to RAK7268V2 and want to connect heltec lora esp32 v2 to RAK7268V2 in OOTA.
Can some body guide me steps or process for the simple way?
Thanks,
Kabin

It should be the same as here: Connect “ESP32 + LoRa” to LoRaWAN Server — esp32 latest documentation
The LNS doesn’t matter in terms of connecting, everything is pretty much the same.
Make sure to flash the LoRaWAN firmware and not just LoRa, they are different things.
