After doing some further testing, it seems that using "inband_2rxhb_2tx.rbf" allowed us to properly do automatic t/r switching (even with the use of just one channel). We could not get this functionality working correctly with "inband_1rxhb_1tx.rbf". Maybe this rbf was not rebuilt after applying whatever fixes George was referring to? Anyway, thanks a lot for your help.
OK so I had interest in this, and I think Brian and I understand why Auto T/R switching does not quite work right with the inband code. For it to switch to the RX chain, tx_empty must be asserted. However, this is a little bit of a misnomer with the in-band code because if you have a packet in the TX buffer pending on its timestamp, tx_empty is low since there really is something in the TX chain... but it's not transmitting! That's the problem. I am working on fixing up some of these things now.
