Kenji Arai / Mbed 2 deprecated BLE_LoopbackUART_low_pwr_w_RTC1

You can control from iPhone and put some command. h=show commands help, v=show TY51822r3 VDD data, t=show chip temperature, q=you can make deep sleep condition.

Dependencies:   BLE_API mbed nRF51822 nRF51_Vdd nRF51_WakeUp nRF51_LowPwr

Fork of BLE_LoopbackUART by Bluetooth Low Energy
