Sample: ble_app_hids_keyboard
Device: EYSHJNZWZ (nRF52832)

I have a question about HID.
In the sample program "ble_app_hids_keyboard", the following values are stored in "hid_info_flags".

    hid_info_flags = HID_INFO_FLAG_REMOTE_WAKE_MSK | HID_INFO_FLAG_NORMALLY_CONNECTABLE_MSK;

I don't know what this value means.
What does this value mean?

Hi, 

hid_info_flags is used to ble_hids_hid_information_t::flags which will be shown in the HID Information characteristic. See HID Information.

Thank you for answering.
I understood what "HID_INFO_FLAG_NORMALLY_CONNECTABLE_MSK" means.

Please tell me about "HID_INFO_FLAG_REMOTE_WAKE_MSK".
The link you gave us has the following explanation:

@name:RemoteWake
@key:0
@value:The device is not designed to be capable of providing wake-up signal to a HID host
-
@key:1
@value:The device is designed to be capable of providing wake-up signal to a HID host

I don't understand this meaning.
What is a "wake-up signal"?
How will it be used?
Please tell me.
