I'll ask this in the other forum, but this is a seperate question outside the reset chip issue. 

I wanted to know if there was any recommendations on the setup and if their would be an issue running on the same SDR.

Well, this is pretty generic to radios in general.

If your RX is tuned to the same frequency as your TX, you'll receive your own transmissions.  Further, due to the proximity of your TX and RX antennae
  (assuming you're running full-duplex), your RX is likely to be de-sensed, even if it's tuned to a different frequency.

Maybe you should ask this on the LimeSDR mailing list.

Incidentally, is what you're trying to do here related to the problem
