I may be wrong but from owning both the D7100 and the TT1 & TT5, I was unable to get them to do more than just trigger the flash. TTL would have been a life savior last night shooting an event. Still I managed to get the job done and it was fun.
@Photophun: What is it that you are trying to do exactly? If the flash fires then they are communicating with each other. Have you called PW tech support regarding your issues to see what they have to say?
D4 & D7000 | Nikon Holy Trinity Set + 105 2.8 Mico + 200 F2 VR II | 300 2.8G VR II, 10.5 Fish-eye, 24 & 50 1.4G, 35 & 85 1.8G, 18-200 3.5-5.6 VR I SB-400 & 700 | TC 1.4E III, 1.7 & 2.0E III, 1.7 | Sigma 35 & 50 1.4 DG HSM | RRS Ballhead & Tripods Gear | Gitzo Monopod | Lowepro Gear | HDR via Promote Control System |
They can only trigger lights until the firmware update. Then they will have the full functionality from controling the speed lights power levels to TTL.
I think the Phottix Odin's have/had an issue with the D7100 as well - Almost makes you think that either A) Nikon dumped/closed some old triggering or Something new is coming. It is odd though.

Apparently they don't support the D5200 or the D7200 yet either :-)
