I maybe want to use several AB01 boards in a project with low volume (~20 nodes)
OK, right now the SPI bus is deeply dedicated to the Lora part on the “other side” of the module.
But think of adding an inverter to the NSS connection, and then selecting “another” SPI bus by this signal.
That way, we can add another SPI device, and we just need to have some software control to this NSS pin.
Is it “theoretically” possible, or are there internal function, which do not allow any delay for re-selecting the SPI bus? E.g. if a packet arrives…
