Resolved! aci_hal_write_config_data() usage

Hello, I use STM32WB05KZ. Could you give me an example about how to store configuration data to NVM by aci_hal_write_config_data() function? - When I tried to store to 0x00 (I used static randow MAC address), it returns 0 but the data is lost when th...

BLE_Heartrate CubeMX

I want to add a EXTI0 line to act as a wakeup. I took the BLE_Heartrate example as a base. Out tyhe box, it compiles & runs ok. When I use CubeMX 6.16 to edit the BLE_Heartrate ioc to add PE0 as the EXTI0, next time I compile, I get an error that I'm...

How to remove the "sinus noise" in IQ sampling mode?

I am using two Nucleo-STM32WL33 board, one as a transmitter and one as a receiver. The transmitter sends two messages in ASK modulation and the receiver records the messages in IQ sampling mode.Below is a visualization of the IQ samples time series.T...

Sequencer never calling idle state

Hello, I am currently working on a ble project on the stm32wb09ke nucleo board that uses the stm32 sequencer. My application is working as intended but I want to make it low power for optimal battery life. If i understand correctly the sequencer itse...
