Hi
I want to know is there any source except timer to wake up the DA14531 from sleep mode? I should mention that I don't access my board, so I would like to wake up it remotely or by a trigger, for example, by sensing the environment.
Thanks.

Hi harry84,
I would suggest you look at ourDA14531 Sleep Mode Tutorial (HTML)and Section 2. Sleep modes overview to see how the DA14531 can be woken up depending on the sleep configuration.
In Extended sleep mode, the system domain except the SysRAM, the radio domain and the peripheral domain are powered down and the XTAL16M clock is stopped. The SysRAM is still powered to retain data but is not accessible. The AON power domain is ON to keep data in the retention RAMs and to supply power to the blocks that can wake the system up, i.e. wakeup timer, quadrature decoder and the BLE timer.
In Deep sleep mode, to reduce the power consumption even further, the SysRAM is also powered off. The status of the other power domains is the same as in Extended sleep mode. The device can wake-up from deep sleep either using clocked-wake up controller, from GPIOs, RTC alarm or Timer1.
In Hibernation mode as compared to previous two sleep modes, the PD_SLP (Sleep power domain) domain is switched off. This means the CRG (Clock and Reset Generator) is powered off and this is why this mode is called Clock-less mode.
The device can wake-up from only GPIOs that is configured to wake-up. The available GPIOs to wake the device up from hibernation is P0_1, P0_2 … P0_5.
Thanks, PM_Dialog
Hi buddy, do check out the tutorial on DA14531 Sleep Mode and you would be good to go with as of now.
