In SDK 6.0 I find there is a project of ble_app_hids_keyboard_serialization.uvproj in nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
and it contain even softdevice part.
Default IROM1 start from 0, so it may work without softdevice v7, am I right?
I compile it but is seems not work, and I can not find any ble device from my Nexus7 II.
So how can I make it work?
Thank you!
