We are evaluating DA16200 Development Kit - Pro with External MCU (STM32L4).
We have made it to send the AT command "AT+DPM=1" to enter into the DPM sleep mode. But we are unable to wakeup it from this state. We tried to wake up from the DPM sleep mode using the GPIO connected to RTC_WAKE_UP2
Kindly advise on how to wakeup from the DPM sleep mode using External MCU.
Also, I am not sure that what is the behavior of the module, if it is DPM sleep Mode. What we observed is, WiFi configuration and socket communication is still alive. Could you confirm this is the actual behavior?

RTC_WAKE_UP2 is disabled in SDK 2.3.1.
Please find attached an image of latest SDK 18.104.22.168 with RTC_WAKE_UP2 enabled.
