The Wahoo Kickr has an ANT+ and Bluetooth Smart connection.
Bluetooth Smart is a low energy consumption technology. The Bluetooth Smart can't be connected on 2 equipments at the same time.
If you connected your Wahoo Kickr on Wahoo Fitness first, make sure you killed the app on your TAB / Smartphone, to disconnect it from the Wahoo Kickr.
Then start the Kinomap Trainer APP, and add the Wahoo Kickr (choose 'Bluetooth Smart 4.0').
Now you should find the Wahoo Kickr on the list.
Note : if you want to use the Wahoo Kickr ANT+ connection, make sure yout TAB / Smartphone support this technology.
