My BLE project on stm32wba65 makes use of "UTIL_TIMER_Create" to set a callback. This works ok when the RTC is configured just as free running binary. If I set the rtc mode to mixed binary & bcd, the callback never gets fired. I'm using an LSE to drive the rtc.
Why is this?
I'm trying to base a project off the BLE_Heartrate example. I need the calendar time & date so I can timestamp data. I synch the time over the BLE from a PC.
I suppose I could just use the ms ticks since boot, but how does this survive a reset (but not power outage)? Is the binary counter derived from the rtc sufficiently large enough to hold a date for a year or more?
Any examples using binary rtc and external time synch would be most welcome.
