Valentin Tanasa / Mbed 2 deprecated nRF51822_DataLogger_PowerImpulseCounter

App for BLE Nano to monitor the power consumption for a specific location, by intercepting the led flashes of a standard power meter. It counts and log the flashes for each second. It works with RedBear App for smart phone (Simple Chat App).

Dependencies:   BLE_API lib_mma8451q mbed nRF51822

Fork of nRF51822_DataLogger_with_Chat by Valentin Tanasa
