Backup registry save and system reset risky for STM32WBA?
Hello everyone, as mentioned in the title, I'm using STM32WBA in a project. Immediately after sending data to the stm32wba coordinator, I add an expression to the backup register and reset the processor using `Nvic_system_reset`. I check this at s...
Resolved! Expansion Board with Quad SPI NOR FLASH
Are there any expansion boards with Quad SPI NOR Flash chips? I am interested in using it with a NUCLEO-WB55RG board.Preferably it should use the Macronix 25L6433FM2I-08G chip, but that is not a hard requirement. This chip is found on the X-NUCLEO-GF...
Resolved! How to design STM32WL55 with IPD for 865MHz
Is there any way to optimize the IPD BALFHB-WL-01D3 to work at 865MHz at 22dbm for STM32WL55? And is there any hardware design guide for power of STM32WL like it is there Hardware design guide for STM32L0 application note AN4467.
BLE: intermittent connect, repeated disconnect reason 0x3E during connection attempts
Hi ST Community,I’m working with STM32WBA (STM32WPAN / BlueNRG-style stack APIs). I’m using Extended Advertising on the peripheral (connectable + scannable, secondary PHY = Coded) and a STM32WBA central that scans and then calls aci_gap_create_conne...
Resolved! ID and PAC query for Sigfox
Hello everyone, this is my first time using an ST microcontroller. Specifically, I am using the MB1389E (NUCLEO-WL55JC1) development board. It has been a bit confusing because most of the tutorials have an old version of STM32CubeIDE where everything...
Resolved! Cannot Flash STM32WB55CEU6
Hello, I have a custom board with a STM32WB55CEU6 and I am trying to programm it through a Nucleo STLink with SWD. The onboard Nucleo CPU is detected and works fine if I add the jumpers, and I can program a different STM32 board with the jumpers remo...
Resolved! STM32WBA5MMG GND pads near antenna
Dear all, I have a custom PCB with the STM32WBA5MMG module. I missed the keepout requirement in the reference design and pads 2 - 5 and pads 56 / 59. These pads are connected to GND in my design. I did some signal tests, and I have a feeling the ante...
