Hi!

Im currently working with a two Xbees S3B 900HP model XBP9B-DMWT-012 ( the wire antenna one ).
However, my application requires one of them to be type RPSMA antenna. Fot this reason, I’m thinking of buying the model XBP9B-DMST-012.

My question is: can they communicate with each other? Is the only difference between them the antenna type?

Another question: If I buy a programmable type, such as the XBP9B-DMSTB012, can I also communicate with both 10K and 200Kbps types?

Thanks so much!
