Hello Sergio,
You can use the "prj_client" demo appplication to test most of the BLE peripherals. In your case you need to enable the HID Host macros in "\prj_client\src\usr_config.h":
#define CFG_PRF_HOGPRH
#define CFG_TASK_HOGPRH TASK_PRF1
Open a serial terminal @ 115200 bauds an go to through the menu to connect to the HID device and Enable the report Mode in the HOGH menu. Make sure that your terminal transmits New-lines as CR-LF ('\r''\n').
The HID device can also be connected to any Bluetooth Smart Ready products available on the market that supports HID devices.
Regards.
