Internal SMPS efficiency (STM32WLE5) around 60%?
Working on a simple LoRA sensor which is powered by a lithium capacitor, I am wondering whether to rely on the internal SMPS or an external buck IC for stepping down voltage to improve efficiency. My measurements of the internal SMPS indicate a effic...
STM32wb55 does not show connected even if connected to the phone
I have my device that is working on FreeRTOS. The main issue is that when I connect my device to an app (a custom or the ST BLE toolbox), I kill the app. If I relaunch the app, the device is not shown.To check why it causes this issue, I check if my...
Resolved! STM32WB09 deepstop mode
Hello,I am working with a STM32WB09KE mcu on a custom pcb. I am trying to write a softwareloop that measures something every x min and afterwards goes into deepstop mode. I was following some online documentation, but it seems like the wb09-series is...
Resolved! VREF+, GPIOs on custom WM7 STM32WL5MOCH6TR PCBA not working
We recently developed a custom STM32WL5MOCH-based board. The VREF+ output is not supplying anything right now. The GPIOs seem to be floating and do not output anything. We're using the Visual Studio Code environment and simply imported the CMake ...
Changing advertising data STM32WPAN
Hello, I have custom PCB with STM32WB5MM module configured as beacon. I am successfully advertising configured data.I have configured a task in sequencer (the task gets executed, checked with debugging). When I leave task empty, the BLE advertises, b...
STM32WL3x: Is there a DBGMCU_IDCODE register?
Hello,Do the STM32WL3x series of microcontrollers come with a DBGMCU_IDCODE register? All the other MCUs in the STM32WL have one, but I don't see it listed for the WL3x series.If it has one, what is the value of that register?If not, is there any oth...
Resolved! When I get connected and paired to peer HAL RNG doesn' work
Having issues generating random numbers while being connected via BLE.In general use, HAL RNG works fine, and I get a random number without timeouts.BUT,Upon finishing the connection flow,connection mtu exchange pairing ,I start to get timeouts when ...
Resolved! Failing to initialize BLE on a custom STM32WB55CGU6 board
Hello,I’m trying to create a simple program to test BLE functionality of my board. The board does not have HSE but it has LSE. I'm not sure if that is a problem. I'm using PlatformIO for the programming, configurations and building/flashing. When I u...
Flash SR errors on startup
Hi all.I'm working on stm32WB MCU, I have a bootloader and an application. The bootloader only check if any update needed and jump to app. When app stops at main I can see that flash status register is set with PGAERR, SIZERR and PGSERR and I have no...
