STM32WL55 RTC with epoch , subsecond conflict with lorawan stack

[anandhu_us]

Hi, 

when configuring the Lora stack it requires RTC in free running mode along with some alarms. I am looking for ways in which I can get epoch time in my application layer. 

Thank you for any comments on this

Hello @anandhu_us and welcome to ST Community.

To get epoch time, I suggest you to take a look to the .ioc file of the project using CubeMX last version. Go to RTC configuration and change the bin Mode to Free running BCD calender and binary mode. Then, Check all general and calendar time parameters.

I hope this help you.

Best Regards.
