Resolved! Where is .IOC file in FUOTA exemple for STM32WL

Hello,I'm using the exemple for FUOTA in STM32WL for single core (STM32WLE). And I would like to know where I can find the .ioc file to change the pinout confirguration of the chip.Thanks

Resolved! Why does BLE stop advertising when STM32WB enters low power mode (STOP2)?

Hello, I am trying to configure a custom board with STM32WB5MMG in STOP2 low power mode. For that, the program calls the PWR_ExitStopMode() function when a timer reaches 10 seconds and exits when EXTI0 interrupts by calling PWR_ExitStopMode(). Th...

Why does BLE become not discoverable when STM32WB goes into low power mode?

Hi,I'm trying to set a custom board with STM32WB5MMG into low power mode STOP2. For that, program calls PWR_ExitStopMode() function when a timer reaches 10 seconds and exits when EXTI0 interrupts by calling PWR_ExitStopMode().The MCU goes into and ex...

STM32 WL55JC1 UART only receiving data once

As the title suggest I only receive data once. I also tried using HAL_UART_Receive_DMA and HAL_UART_Receive_IT still got the same result (only receiving once). I'm using Teseo-LIV3FL GNSS module and I've tested it before on my ESP32 and it works as e...

LoRa synchronization point to point

Hello!I use two stm32wl55jc1 boards for a point-to-point connection via LoRa, simple, without a gateway. Everything goes well until I introduced the possibility to change the communication parameters (press a button and enter on UART). After the inpu...

Resolved! How to edit an existing .csv file in the SD card?

I want to save constant data on .csv files in an SD card. I managed to create the file, but when I call the function to edit, it seems not to recognize the end of the file to start writing. How can I do that? Or what can I do different? That's the pa...

ZigBee Coordinator on STM32WB5MMG with Off-The-Shelf devices

Hi All,I am quite a newby regarding ZigBee since I have been playing around with this since bare a month now. So please be patient if my question might sound stupid or my terminology is not quite "ZigBee-conform".Short form of my question: Why do non...

Do anyone have sample code of using UART or USB CDC by modifying Ping Pong (STM32CubeExpansion_LRWAN_V2.1.0)application in B-L072Z.

STM32WB55, SFSA value is 0x00 (0x0800 0000). Is there a way to execute some code for CPU2 from RAM to modify the SFSA setting?

I think, I have "bricked" my STM32WB55 Nucleo board.I can connect the board in system boot mode via ST-Link in ST-Programmer. The SFSA value is 0x00 (0x0800 0000).Because SFSA can only be written by CPU2 and embedded flash is write protected:Is there...
