Keyboard with ble communication

Question

I would like to have a ble communication between a keyboard and a computer. The keyboard will be connected with a nordic chip, but what can I use on the other side? 
 Do I have to use the nordic dongle PCA10000? Or is it possible to use other ble dongles? 
 If not, is it possible to purchase only the nordic dongle?

recent computers have BLE built in. windows 10 computers, new macs etc.. You can communicate with this using BLE HID example we provide no problem. Otherwise you can buy the dongle here: www.nordicsemi.com/.../nRF51-Dongle 
 I'm sure it is possible to use other BLE dongles. You will need to establish a BLE link with the keyboard from whatever dongle you use and then send info received over BLE to the computer over USB. If you can use USB HID your life is much easier because you dont have to write a driver on the PC side. 
 Our BLE_HID example with a computer that is already BLE enabled is a great and easy starting point. Get something working here and then if you need to use the nRF51 dongle because this will be more complicated and it will be nice to know that your keyboard is working and any problems are on the dongle, computer side.
