I miss the 32768 Hz crystal, mandatory for low power applications.

ah, i think 32768 hz crystal is not necessary for normal mode, should i have to add it ?

For the BLE part to work, it's important that both the schematic and the layout is a copy of our reference layout. I would recommend you to read the tutorial "General PCB design guidelines for nRF51" for how to do the layout.

The 32 kHz crystal is not mandatory BLE, you can use the internal RC oscillator instead.
