Here: DS 1.2.0: Traces when in FCM Data Mode - #3 by awneil
Is it correct that 1.2.0 does not support “pass-through”?
Yes, I think that is the case.
If 1.2.0 does not support “pass-through” where do we download a suitable version of TMT?
It was included in the SDKs before M2MStudio, but the easiest way is to ask your Distributor.
Will this TMT version work co-operatively with 1.2.0? (as previous releases of DS did)
No.
One of the major changes in the Target Management “refactoring” was to remove Selima - which TMT Relies upon.
You should still, I think, be able to use TMT with an application built by DS 1.2.0 - but TMT cannot share a comms link with DS 1.2.0.
