Hi,
We have a customized board with STM32F103, it measures water level and sends the data to a server, and then enters into Standby mode for 1 minute after setting up a RTC alarm for wakeup.
Occasionally, we see wakeup failures. This happens randomly, it could be once after running for thousands of minutes, or could be once for hundreds of minutes.
Any ideas ? And is there any way to check the reason why it happens?
Any replies would be highly appreciated.
