periph_init

Hello
我想使用需求方的项目(dsp 5.150.2)。我的广告ded one characteristic to control GPIO at DSPS original project.
I can check the gpio is changed when I change the value of the characteristic.
The problem is that 'BLE_WAKEUP_LP_Handler' is continuously called which is calling the 'periph_init' function so that the gpio's state goes back to default state right after changing by BLE.
Could give me some advice about this?
