Receiving LoRaWAN downlink messages

[ask-gh]

Hi,

Thanks again for all the hard work, this is a great project!

I wanted to know whether there is support for capturing downlink messages. If so great!

I saw in this issue #44 that if you are sending a downlink you would have to either: 2) modify the code of the modulate block to use downchirps as reference 3) take the conjugate of what comes out of the modulate block.

Would a similar case hold for receiving such messages?

If you could point me in the direction of how to implement this, that would be really appreciated.

Cheers!

Hello @ask-gh,
yes, you would need to use the complex conjugate of the signal.
Adding a simple complex_conjugate block before the frame_sync might to the trick.
