PNUCLEO LRWAN3 Connection Issue

[Premauda]

Dear ST Support Team,

I am currently working on verifying a LoRaWAN proof of concept using STM32 hardware.

My setup consists of a LoRaWAN end node and a gateway connected to the Loriot network server. From the Loriot dashboard, I can confirm that the gateway comes online successfully whenever powered and is in a ready state, waiting for packets.

However, my end node has not been able to successfully join the network.

I have carefully verified the following possible causes:

• Frequency configuration (ensured no mismatch between node and gateway region)

• LoRaWAN region settings

• DevEUI, AppEUI (JoinEUI), and AppKey configuration

• Network activation method (OTAA)

• Gateway operational status on Loriot dashboard

All parameters appear to be correctly configured, yet the end node consistently fails to join.

I would appreciate your guidance on:

1. Additional debugging steps to determine why the join procedure is failing.

2. Recommended methods to confirm whether Join Requests are actually being transmitted from the end node.

3. Any known configuration considerations specific to STM32 LoRaWAN middleware that may affect the join process.

For context, I am using:

• Board: STM32L073RZ / P-NUCLEO-LRWAN3

• Gateway model:  STM F7/P-NUCLEO-LRWAN3

• LoRaWAN Region: EU433

• Activation method: OTAA

Thank you for your support.
