I want to ask something about the compatibility issue of the sub-1Ghz radio.
If I am using two different RF chips (such as TI's cc1120 and Silicon Labs' si4432; both have FSK modulation), can they communicate with each other?

I have read the datasheets (however I am not a professional communication engineer, so I cannot quite understand all the details...).
For example, both cc1120 and si4463 have GFSK modulation, they both support the same frequency range, they both can hop frequency in several tens of us.
Some chip support FEC and digital encoding, but for compatibility's sake, these features can be disabled.
I have searched the internet, however haven't found someone do this kind of experiments. Do you guys know someone who has experiences on this? Thanks.
