Hi Sara,
Do you mean if there is any ready simulation scenario to try out GTS?
Application is not enabling/restricting the MAC in any way. You can use
any MAC with any app, and of course you will see different results for doing so.
So in the case you are interested in a existing simulation scenario that uses GTS
then the batchRun script in the BANTest simualtion dir is what you want.
Read section 3.5.2 of the User's Manual for a short description.
The MAC-related parameter to enable and use GTS are described in page 57 of the manual.
GTS is a TDMA scheme. TDMA is a MAC technique, it is not a specific protocol/scheme.
