Raspberry pi 3 b or raspberry pi 4

why it is necessary to use Raspberry Pi 3 model B only in gateway ? what are the main basics ? i have raspberry pi 4 , can i use it instead of rpi3 ?

Hi tek, Do you have any update on this? I have the same question.

Hi @meomap887
answered in another thread.

The 1Gbit interface generates too many interrupts so it is not possible anymore for kernel to maintain precise timing that is needed for SPI communication. There is no workaround for it.
