The DCF77 recevier is not a robust solution to get the atomic clock.
Analog therefore it depends on the signal strenght, weather conditions, environment status.
Optimal solution can be a GDP modul usage instead of the DCF77 receiver modul.
HW schematic and layout have to be changed.
New driver is needed to be implemented (HAL, new interfaces, new state machines)
