How to call Random Static Address in the past

Hello, I am developing a BLE HID device using the STM32WB55.I am generating random static addresses using a program implemented in the STM32CubeWB. This is used to identify multiple peripherals with the same functionality. #else /* Get RNG semaphor...

LoRaWAN FUOTA over AT command using STM32WL as Slave device with STM32L4 master

Hello Developers,In our current project, we are using STM32L496 mcu along with STM32WL chipset loaded with AT Slave example to communicate with LoRaWAN network. We are able to send/receive uplink and downlink from STM32L4 end device to LoRaWAN serve...

Resolved! Is it possible to guide the HSE clock to MCO pin?

Hi,I would like to use the STM32WBA55 controller and forward the clock of the HSE to the MCO pin. The data sheet states that this is only possible for internal clocks:Clock-out capability:– MCO (microcontroller clock output): outputs one of the inter...

STM32WB Errata "CPU2 hard fault when changing C2HPRE clock divider in RCC_EXTCFGR on CPU1"

Hello!The errata states this as a workaround for this errata:DescriptionWhen CPU1 switches the system clock frequency, the C2HPRE divider may need to be updated according toCPU2 frequency requirements. Changing the C2HPRE divider by CPU1 when CPU2 is...

Resolved! STM32WB55 AES2 bus faults when bonded over BLE

We are working on a product on the STM32WB55 that is hard faulting when trying to modify AES2 peripheral registers while actively bonded to a Windows PC over BLE.What we discovered is that we can use AES2 to encrypt and decrypt just fine, but the mom...

STM32WB55: Correct way to clear I2C3 interrupt at the peripheral

Dear community, We are currently developing custom firmware for an upcoming device based on STM32WB55. It's written from scratch, including a very simple cooperative scheduler. Recently, we rewrote our I2C driver. Ever since, we occasionally see one ...

CMWX1ZZABZ (STM32L0) external reset issue

Hello,I have a custom board, equiped with a Murata CMWX1ZZABZ, running a firmware based on the LoRa and SigFox libraries provided by ST. Several hundreds, if not thousand, units are currently depoyed. For the most part, everything is fine.See the att...

[STM32WB55] Flash operations without Wireless Stack and without using CPU2

Hello!I have a question about doing flash operations without the BLE wireless stack firmware being present in STM32. As it seems from the examples, the flash operations requires to notify the CPU2. For example, when doing flash erase, the CPU2 will h...
