Kenji Arai
this is a new program based on BLE_Uart_Peripheral. Change program name due to relation Client&Peripheral to Client&Server
Dependencies: RingBuffer nRF51_Vdd nRF51_WakeUp
This is a BLE Server (Device) program for nRF51.
You can communicate with mbed BLE using "BLE_Uart_Client" program as follows.
