Hi,I access the system bootloader by setting the bits nBOOT0/nSWBOOT0 = 0 and nBOOT1 = 1 in my code. I manage to connect via UART and flash my new firmware but then my MCU does not reboot because it remains in the system bootloader. How can I do this...

Hello,I having an issue with the LSM6DSL. It's doesn't trigger interruptions on INT1 or INT2.I'm working with the STM32WB10CC and I'm connected through SPI to the LSM6DSL. The SPI is working I'm able to communicate with the sensor but it's not trigge...

Hi,I'm working on STM32WB10CC with 320KB of flash memory.I'm using the full ble stack 1.14.1 (stm32wb1x_BLE_Stack_full_fw.bin) which has a size of 148KB.In the release note it's written you have to put it at this address 0x08021000.If I'm doing the m...

Hi,I'm looking for the max size of SRAM allocated for the GATT database for the STM32WB series.I've found the informations for WB55 and WB15 but I can't find the information for WB10/30/35/50/. Does anyone know these values or how it can be calculate...

Hello, I'm trying to flash my STM32WB15CC using UART1 without using pin BOOT0(PH3). I'm using a NUCLEO-WB15CC. For that I know that I've to set some bits in OPTR register and jump from application code to memory system bootloader and then connect to ...

I don't know which MCU you are using but in my case with the STM32WB I had to define my gpio state before going in SHUTDOWN mode using :LL_PWR_EnableGPIOPullUp(LL_PWR_GPIO_A, LL_PWR_GPIO_BIT0); //LL_PWR_EnableGPIOPullDown : for pull down LL_PWR_Enabl...

Hi Federica,I solved my problem. I was having an issue with the CS pin on my SPI bus. I was able to communicate with the sensor, but only for a single request; all subsequent requests to configure the LSM6DSL did nothing and didn’t return an error. L...

ST helped me solve my problem by telling me that I had to put the SPI pins in pull-up when the STM32WB is in shutdown.I used the following functions:- LL_PWR_EnableGPIOPullUp- LL_PWR_EnablePUPDCfg() Thank you for the PCB layout. Please note, that it...

I think I have the same problem except I'm using a STM32WB10CC with SPI connection to LSM6DSL. The current consumption seem to be approximately the same. I sent the commands to put it in power mode but the current is still higher than expected.I trie...

Any news on this subject ? I'm trying to do the same.
