Unexpected different results when building BLE_TransparentMode example

I've tried building and flashing the same BLE_TransparentMode example on an STM32WB5MMG-DK board from two different sources which gives me two separate results. Once straight from the latest MCU package found in https://www.st.com/en/embedded-softwar...

Resolved! High frequency uplink with STM32WLE5JC

Hello, I am working on a project using the STM32WLE5JC module and STM32CubeIDE for development, with firmware packge v.1.3.0.We are currently running EMC tests at a test facility, and they have requested for the ability for the device to send data ev...

Request for Suggestions: Low-Power Bluetooth Device Design

Dear Team,I am currently working on designing a low-power Bluetooth device and we need a suggestion as to choose an ultra-low power consumption and distance to meet BLE MCUIn particular, I am looking for advice on:Selecting the best STMicroelectronic...

Resolved! B-WB1M-WPAN1 P2P Client

Hi,I am attempting to get two B-WB1M-WPAN1 boards to connect to each other, one acting as a server and one acting as a client. I am fairly new to ST programming and thus I rely heavily on the examples and documentation to guide me. I have found an ex...

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 ...
