Hi Pavan,
The obvious difference is that the ANT chips in the TI kit will be TI parts (CC257x chip family). Otherwise, they are mostly the same.
There are a couple of small differences. The current Nordic kit contains AT3 modules which will not be in the TI kit.
Instead of I/O boards (buttons + LEDs) the TI kit will have EEPROM boards which will allow for testing of the embedded ANT-FS feature on the TI parts.
This is all subject to change in future releases of the kits.
Regards,
Jefferson
