Si4737 I2C Arduino Radio Breakout

Thanks

As I implied, sorry needed to know what level to start, If I'd started to talk VSWR to a student on their first project, it would not have helped.

Ok, so :

comms. If I rember, the chip has a revision register, does that read back just fine ?
the question about the scope is because spikes on the comms lines from the closely coupled radio can cause mayhem to comms, what seems to be working at the terminal just does not get to the chip corectly.

The question about the app note was simply , its amazing how many people dont use the app notes. Well done.

Re the eval board, you see my time is worth a few dollars per hour. So a hundred for a known working demo board on which i can dev the software is to me a good bet. allows us to dev the software before I get boards back. just a suggestion. The problem you now have is , is it thee software, the compiler, the connections, the board or the understanding of how the chip works.

If you had a known good to work from then things might be easier.
