annotate Small_CPU/Inc/uart.h @ 939:f41974734268 Evo_2_23 tip
Resume UART com with gnss after sleep:
Some changes were needed to get the communication up and running again after the gnns modul was set into power mode. The config needs to be safed at shutdown and the receiver needs to be wake up using dummy bytes before real communication may be resumed
