Lora receiver don't work when the sender use LoraWan

#1

Hello. I am trying to receive messages with a heltec device WiFi LoRa 32(V3) using Lora Basic, and the transmitter is another heltec using LoraWAN.
I would like to see the encrypted messages on the receiver, but I am not receiving anything.

What can I do?

Thanks

You can view encrypted information through the logs of the server device

Hi. Thank you for your answer. What do you mean by server? Where can I see the logs?
For more details: I am using two heltec devices, one as a receiver and one as a transmitter. But instead of loading Lora (basic) code on both, the transmitter is LoraWAN and the receiver is Lora. This is because on the Lora receiver I would like to be able to see what an encrypted LoraWAN message looks like.

This is potentially possible if you invert the IQ and have a way of knowing which channel the LW device is going to transmit on - first is code, second is going to be lucky guesswork.

Or you could use a gateway. Or output the payload from the LW device as it is sent to the radio.

Without knowing the why, why you want to do this, it’s hard to advise.

For an accademic project, I need to intercept LW messages with the Lora device. On the LoraWAN device in my experiment the frequency, bandwidth and channel are fixed.

Why? The results are the same if you “intercept” it with a gateway or just look at the payload sent to the radio.

Personally I don’t do other peoples home work because no one has yet sent me part of their degree certificate or cited me on their paper. I’ve already given you the core issue to attend to in my previous reply so you can research that. Given the rather odd situation of both the “experiment” and it’s your job to research the how to, this will probably make faster progress than waiting for someone to figure out how to do it for you.
