ESP32 V2 & LoRaWan & RAK2245 - Help Needed

Hi,
I am facing issues to connect ESP32 V2 to my LoraGateway (RAK2245 - 915MHz).

I am using <ESP32_LoRaWAN.h>

Keys are ok!

Does the board only works with Heltec Gateways?

Any help?

Here is the output of my debug messages from the OTAA example (library).

the nodes are working with all LoRaWAN Gateways.
have you checked the frequencies?

RAK’s gateway seems not set to the default listening channels for each band. You need to set the listening frequency to the channel’s node use.

Is the gateway working with other LoRaWAN devices, so we can see if its a gateway or device issue. We’re assuming gateway is setup right, ie as per these instructions on a pi https://doc.rakwireless.com/rak2245-pi-hat-edition-lorawan-gateway-concentrator-module/configuring-the-gateway
