So you are using the uart example code and using RTC as the wakeup source, right? I unfortunately don't understand what you mean by "is baudrate set to <115200 sleep mode at 50ms+- periodic wake up." Could you try to rephrase this please?

This case could possibly be helpful for you. Might also be useful to take a look at this case and this one. Lastly, this one could be helpful too. Hope that helps a bit!

Kind Regards,
