Hi,

[quote user=""]err_code = ble_nus_on_button_change(m_conn_handle, &m_nus, button_action);[/quote]

You need to register a BLE event observer using the NRF_SDH_BLE_OBSERVER macro. Example:

ble_lbs_c_t instance;
NRF_SDH_BLE_OBSERVER(anything, BLE_LBS_C_BLE_OBSERVER_PRIO,
                     ble_lbs_c_on_ble_evt, &instance);

Take a look at ble_lbs.h in the ble_app_blinky example. See here for more documentation of the LED Button Service.

Regards,
