if(v != 0x12 & v != 0x13):

This should be &&, not &. Or else if ((v & ~1u) == 0x12), which might be smaller on AVR. Ideally, this would be a macro or inline check: if (is_sx1276_like(v)), where is_sx1276_like() looks at v and makes the decision.

We've not heard more on this since the last few years; has Semtech documented this? Or is this not relevant after all?
