Hello everyone,I have designed a custom PCB with STM32WB15CC. I am using two sensors (VL53L1X and MPU6050). I am using CR2032 coin cell as a supply and I have big problems with the battery management. The project example is using sequencer and what I...

Hello everyone,I have recently created a new project for my development board NUCLEO-WB15CC from STM32CubeIDE. There are some conflict in sizes of SRAM2 and FLASH. In the RM0473, SRAM2a is described as 32KB and SRAM2b is described as 4KB and these ar...

Hello everyone, I have recently started learning C language and I am kind of new into embedded systems. I am using NUCLEO WB15CC and trying to develop a system using VL53L1X with MPU6050 sensors. I am getting two sensor data successfully every time I...

Hello, I have recently started coding and learning C language. I implemented VL53L1X drivers to my NUCLEO-WB15CC and I am able to get measurements over USART communication. However, I would like to get these measurement results over Bluetooth and I w...

Hello,My SFSA value is 0x0801c000 and this indicates that my FLASH size is 112KB. Am I right? Why this value is different than the values mentioned in the created linker script and in the reference manual?

Hello, From the reference manual, SFSA option bytes are stored at flash memory address 0x1FFF7870.From the CubeIDE, SFR address location is 0x58004080 and SFSA value is 0x38. I checked both addresses 0x1FFF7870 and 0x58004080 and the value at these a...

Okay, I figured out that the problem was because of the loose jumper wires and my while loop. The program actually works as intended inside the while loop but when I leave the bluetooth connection I am not able to connect back to the device because i...

Thanks for your replies, both sensors have different I2C address. I put a breakpoint on while loop at line 8 at the first code snippet and I receive acceleration of X axis data until it gets into if statement. Then I step over until I receive data fr...

Hello, Thanks for the fast response. I am able to start my sensor measurement by using write to characteristic function. I also created a read characteristic and I am passing the return value of my function there.Best Regards
