Sband Radio Library

[KhushThakor27]

Hey,
I am using the Circuit Python driver for the Semtech SX1280 LoRa Chip. For this I am using the sx1280.py library in order to communicate effectively with the Sband Radio. In the source code of sx1280.py a method is defined as receive_mod() which looks like it used to receive and build packets from another radio. However the example_rx.py file uses the function named receive(). I wanted to know what is the difference in functionality of receive_mod() and receive() function? If I wanted to use this library in order to have effective communication for two radio, which function would be better choice?

Hey @KhushThakor27, thanks for posting your question! Correct me if I'm wrong, but it sounds like you're talking about my circuitpython sx1280 driver here https://github.com/maholli/CircuitPython_SX1280

The difference between my receive and receive_mod functions are an example of hasty coding (on my part). But the short answer to your question is: you should use receive_mod. I named receive_mod the way I did so I wouldn't get the functionality confused between the sx1280 lib and the adafruit_circuitpython_rfm9x lib. Then at some point I decided I wanted a "receive raw quickly" function that I hastily name "receive," but should have named it something better. As the repo states, the sx1280 lib is very-much a work in progress :)

With that being said, to fully understand what each function is doing, I encourage you to step through the code (which is fairly easy to do with python). link to receive method, link to receive_mod method. When you compare the two, you can kind-of tell that receive is doing some of the same stuff as receive_mod, just without any of the important checks or radiohead stuff.

I hope that helps! Let me know if you have other questions.

Thank you very much for your reply Max! I am currently in the process of stepping through the code using Python and taking note the difference in listening using both receive and recieve_mod. As more questions come up I will definitely update this thread.
