When I developing application with nrf SDK,I can set device name by sd_ble_gap_device_name_set().
But when I turn to NCS,I should set device name such as CONFIG_BT_DEVICE_NAME="nRF_DM".
However,I want to change name automatically when application running.
And not only string,I want to assign a char array to device name.
What can I do to arrive it?
