Difference between util_spectral_scan and the legacy util_band_survey #185

Closed sp193 closed 2 months ago

sp193 commented 2 months ago

Hi.

What's the difference between util_spectral_scan and util_band_survey? Sometime around 3.0.0, util_band_survey was removed without any explanation. From the documentation available, it doesn't seem to require a FPGA, so it seems to be usable for the older/basic SX1301 gateways.

Does this (older) design have any notable limitations, compared to the new util_spectral_scan tool that involves the FPGA?

I suppose I ask out of curiosity, since there's no documentation on the inner workings of the SX1301. Why/why not some things are done.

Thanks in advance.

Hi, To be honest we have no history about this util_band_survey utility, so we won't be able to support you. Still, you can try it and see it it does what you need.

The util_spectral_scan utility provides the ability to perform the spectral scan in background, while the sx1301 operates as a LoRa Gateway. That's why it requires the FPGA and an extra radio.

Unfortunately, I cannot give you more details about possible limitations with util_band_survey due to lack of history.

Best regards, Michael

Hi, hello.

I understand. Thank you for taking the time to explain. If I somehow find this tool very useful, I will mention what I find.
