Tom Gilbert / Mbed 2 deprecated Q_BLE_SecureHeartRate

Fork of BLE_SecureHeartRate : should this 'work' i.e. require a secure connection on an nRF51-DK? Hopefully I'm just missing something obvious - or is this broken?

Dependencies:   BLE_API mbed nRF51822

Fork of BLE_SecureHeartRate by Bluetooth Low Energy
