Lora SA(Spectrum Analyzer)
RF Spectrum Analyzer using Lora Radio
RadioLib SX126x Spectrum Scan
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.
The spectrum analyzer perform power measurements in the configured bandwidth.
To show the results in a plot, run the Python script RadioLib/extras/SX126x_Spectrum_Scan/SpectrumScan.py
VSCode Platform.IO development env installation
- Install VSCode
- install Platfor.IO extension
- Connect ESP32 to USB. Install USB drivers for Windows
- Clone this Git Repo or download zip of the sources
git clone https://github.com/Genaker/LoraSA.git
NOTE: in you case name will be Just LoraSA. I have LoraSA2 because I already have LoraSA folder
6. Open the Project with the VS code Platform.IO
-
Select Proper Environment
