CPU2 Hard Fault on appe_Tl_init();
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...

Change LPUART clock from LSE to HSI after wake up from STOP2
Hi, I'm using an STM32WL5MOC where the LPUART is used to wake up the module from Stop2 mode. Since I have a lot of data to transfer, I would like to ask how I can switch to the HSI clock after waking up, and then, of course, switch back to the LSE to...

Resolved! [Solved] STM32_Programmer_CLI returns incorrect BLE Stack Version after programming
Issue Description:I am using the `STM32_Programmer_CLI` to flash the BLE Wireless Stack on an STM32WB series MCU. However, after the programming process is complete, the memory read returns an unexpected value at the Stack Version address, even thoug...
Resolved! Using STM32WB55: FreeRTOS osThreadFlagsWait can return osErrorTimeout early
I have come across an issue which I believe is a bug in the implementation of the osThreadFlagsWait function. Scenario A thread is waiting on a flag (e.g. 0x2u) for a timeout above 0, before this timeout should occur, there are multiple other flags s...
