I have connected a peripheral to STM32WB via I2C,.The functions HAL_I2C_Mem_Write() and I2C, HAL_I2C_Mem_Read() are designed for upto 16 bit register address. (The function checks if MemAddSize is 8 bit or 16 bit).Do I have to rewrite the implementat...

I have observed, using a frequency counter, that the HSE clock on Nucleo board (after using the calibration value in the OTP memory) is off by around 20ppm. I have configured the SYSCLK to HSE_SYS. Now, HAL_GetTick counts the tick from the derived c...

I am getting stuck at SVCCTL_UserEvtFlowStatus_t SVCCTL_App_Notification( void *pckt ) function inside app_ble.c. Is there any documentation which would tell how this part of the code is written?

I understand. Thank you for the direction. :)

Thank you Clive for the quick reply and the information. I'll look into the TCXO sources and GPS based timekeeping. Could you elaborate on ST's different method on accommodating the errors.

I am stuck at a similar problem. Could not get the ble advertisement. I followed the application note 13.1 for initialization process but still not working. Let me know if you figure it out. Thanks Harsh

did this fix work for you? because I have a similar problem and still not able to advertise. Do I need to add more settings/ configuration. I followed the steps mentioned in application note 13.1 .

How in-accuracy of SYSCLK affects the HAL_GetTick?

STM32WB Why the value is set to 0x3A for CFG_BLE_PREPARE_WRITE_LIST_SIZE in most of the BLE examples

After the new firmware package for STM32WB, v1.2, I am not able to see the STM32WB on COM port after running a simple USB CDC code to enable serial communication.

With the Custom P2P Server configuration, how to enable the BLE advertising ?
