gkroussos 0:e8fdba0ed044 2 LAB EXERCISE - Simple BLE Beacon
gkroussos 0:e8fdba0ed044 3 ----------------------------------------
gkroussos 0:e8fdba0ed044 4 In this exercise we will create a BLE beacon which transmits data to
gkroussos 0:e8fdba0ed044 5 other devices.
gkroussos 0:e8fdba0ed044 6
gkroussos 0:e8fdba0ed044 7 GOOD LUCK!
