Javier Montaner / Mbed 2 deprecated BLE_pstorage

Sample application that shows the use of persistent storage (pstorage) in Nordic nRF51822 tigether with a BLE service

Dependencies:   BLE_API mbed

Simple example that shows the use of pstorage (persistent storage) in nRF51822

The code is based on an example proposed at Nordic Developer Zone:
