Some of the first steps toward working with Arduino is understanding how to write code for it. The good news is that it's made with beginners in mind.

In the above scenario, the new library will generate a blocking SPI transaction, thus allowing the first main loop SPI transfer to complete, before attempting the second transfer.

But thanks to the rtl_433_ESP Arduino library developed by [NorthernMan54], we’re now able to pack that functionality into a much smaller package.
