Hello, and thanks for reaching out.
Is there a particular piece of sample code you are using? If you want to take a look at our “peripheral_server_sleep”, you can verify the DIO status during sleep by monitoring LED_DIO.

Before entering sleep, the code will set DIO (LED_DIO) to output low.

The DIO (LED_DIO) will remain low when the chip is in sleep mode.
After wakeup, the code will set DIO (LED_DIO) to output high.
