Hai simon!

Thanks for the reply.

What you explained is very clear and it helps to make the device sleep and wakeup.

but I need for example if I have sensors and ble services when ble is in sleep mode sensor has to wakeup means reading of values/data.

Is that happens in nordic? can you help me with this task?

When the chip is in System ON mode, it will wake up from any event/interrupts, including BLE events, timer events and interrupts from various peripherals. The system will wake up, run the associated handler of the interrupt/event and go back to sleep again.

Best regards,

Simon
