Hello,I am trying to setup the BLE stack on my custom board without LSE using a STM32WB55CEU6. I have multiple boards on hand, on the first one, appe_Tl_init(); worked fine and I got to the BLE stack initialization code. However BLE never worked due ...
Resolved! RTC with Free Running Binary Mode and Calendar Mode STM32WBA65
I have question on STM32WBA65RI uC we are using it for our products TEK923/926. It seem to me that BLE stack doesn’t allow to use Free Running Binary mode and Calendar Mode.There is option of MIX Mode in CubeMX but doesn’t seem working. Causing not t...
UTIL_TIMER_Create with RTC in mixed binary & bcd mode
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 dri...
