ble-connection power consumption=1mA

Hallo everyone!

I need very low consumption when BLE working. according to S110 SDS, BLE power profile section, when BLE in idle-connect, there is Ion+Irtc+Ix32k, same with advertising idle, about 3.7uA.

My custom board has nrf5188,external 16M crystal, 3v battary, config ble_stack_init with RC32k(8000ms CALIBRATION), used peripheral power contral to disable all unneed peripheral, just maintain softdevice needed(RADIO,RTC0,TIMER0,CCM,AAR), and use code"sd_app_event_wait()" in main function.

The advertising interval=1s, timeout=60s minimum connect interval=1.5s, maximum connect interval=2s, slave latency=0, connection supervisory timeout=6s

The results is,when advertising, idle consumption is about 10uA, but when connect, consumption is 1mA.

Why connect consumption so high? where can I config?
