Unexpected behavior using SW vs. HW SPI on ESP32 with the SX127x LoRa module

to be honest, it took me several hours to figure this out, when I tried to use it the first time ;-)

Glad to know I'm not alone 😁

Which hardware are you using to captured the radio outputs?

I'm using the HackRF One I bought a few years back, it's been priceless! When a signal is not received, it's invaluable to know that the transmitter at least tries to do something--that's a good half of the setup I don't have to debug right there ⭐⭐⭐.
