Si4703 on Nano Atmega328P write fail

[gbatalski]

Hello,
i'm facing following problem with my setup:

Radio...
>init()
Write Fail:2
Write Fail:2
>setBand(1)
>setFrequency(8930)
Write Fail:2
>_waitEnd()
>Seek limit hit
Write Fail:2

I've tried with different libs. I can read (try to read) rds data or change the volume value but any channel operation hangs. What could be the problem? Do i need a level shifter on a4,a5,d2 for Nano?

Regards,
Gena
