RadioLib SX126x Spectrum Scan
|
|
|
|
This code perform a spectrum power scan using SX126x.
|
|
The output is in the form of scan lines, each line has 33 power bins.
|
|
First power bin corresponds to -11 dBm, the second to -15 dBm and so on.
|
|
Higher number of samples in a bin corresponds to more power received
|
|
at that level.
|
|
|
|
To show the results in a plot, run the Python script
|
|
RadioLib/extras/SX126x_Spectrum_Scan/SpectrumScan.py
|
|
|
|
WARNING: This functionality is experimental and requires a binary patch
|
|
to be uploaded to the SX126x device. There may be some undocumented
|
|
side effects!
