Sleep mode function in nRF51822 with out any stack

[kvrb]

Hi,

I am working nRF51822 communication. I am using nRF peripherals examples in SDK 11.0 series.

I would like to know the sleep mode examples in communication like after Tx is sending a packet it has to go for sleep mode for 15 sec.

I am getting all examples code in BLE stack etc. I am looking for without any stack. can anyone help me out of this?

Thanks in advance.

Hi,

There are some examples of sleep mode using GPIO and GPIOTE on Nordic's Github page. If you want to sleep for a given amount of time, you will have to use timers to wakeup on a timer event. Check out the Application Timer tutorial, the Timer driver documentation and the Timer Library documentation. In system off mode, all clock sources and peripherals on the chip are turned off, and the only wakeup source is reset and pin change. This means that wakeup from sleep using timers is only possible in system on mode.

See chapter 3.4 in nRF51822 Product Specification v3.3 for more details about power modes.

Best regards,

Jørgen
