We have using nrf5340-nrf7002 in our custom board. SDK version 2.6.1
We understand that the timer will not function in System OFF (deep sleep) mode. However, our project is battery-operated, so we need a sleep/low power mode to minimize power consumption.
In our products, we have planned to implement a periodic interval cycle for10-minute sleep/low power mode and wakeup using an RTC timer interrupt. We want use the RTC to set/get calendar time.
1 How can we achieve similar functionality in nRF5340?
2. Could you please advise us on the available low power modes in nRF devices and, specifically, how to wake up from System OFF using a timer interrupt?
