LAUNCHXL-CC2640R2: SDK v1.40 Which BLE Keyboard Profile should I use?

Hi,

I am trying to implement BLE Keyboard using CC2640R2 Launchpad. I notice there are several BLE Keyboard Profiles at SDK v1.40, here below. What should I use for TI CC2640R2F Based BLE Smart Keyboard?

hid_dev_kb_m
hid_dev_kbd
hid_dev_kbd_cc
hid_keyboard

Hi Markel,

hid_dev_kb_m enumerates as a keyboard and mouse
hid_dev_kbd enumerates as a keyboard only
hid_dev_dbc_cc enumerates as a keyboard and a consumer control device (A/V remote)
hid_keyboard also enumerates as a keyboard only (might be a stale hid_dev_kbd).

To add to the confusion, the BLE Example pack also has a voice of HID (keyboard and consumer control) profile.

I don't know what you end-goal application is, but I'd suggest to start with the hid_emu_kdb example in the BLE Example pack. See:
software-dl.ti.com/.../bleapps_examples.html

Hi Tom,

I decided to use hid_dev_kbd BLE Profile which is same used in this CC2650 Bluetooth Smart Keyboard Reference Design.

I am porting the code to work for TI CC2640R2F Launchpad. My end goal project is a CC2640R2F BLE Keyboard that is powered by 2 AA Battery.
