Using E32-433T30D module

Hello,

I have successfully built a SX1302 LoRaWAN Gateway HAT on Raspberry Pi and connected it to TTN. The gateway appears online and working.

Now, I want to use an ESP32 with an E32-433T30D (Ebyte LoRa module) as my end node.

Gateway: Raspberry Pi + SX1302 HAT (working on TTN)

End Node: ESP32 + E32-433T30D (UART-based module)

Goal: Send data from ESP32 node to TTN via my gateway

Could anyone help me to understand:

1. Is it possible to interface the E32-433T30D with TTN?

2. If yes, how should I connect and configure it with ESP32?

3. Could you share any example code or guidance for sending data from ESP32 + E32 to TTN?

Thanks in advance for your support!
