Using VBAT pin for monitoring battery voltage in STM32 microcontroller
I am updating a PCB design that uses STM32WB35XX series microcontroller and 3 V CR2032 coin cell battery. I want to monitor the voltage level of this battery using the VBAT pin of the microcontroller. I know that is possible as specified in the pictu...
Resolved! Is there any way to read the comparator's output voltage without connecting the output pin to the ADC?
I know the microcontroller has built-in comparators and I'm trying to use it as a transimpedance amplifier. So, I want to test the comparators but the Necleo-WB55 developer kit doesn't have built-in comparators. So, I have to test it on my custom boa...
How to change advertising structure order in BLE
I am using STM32WB55 controller for BLE. I am using it with peripheral lite example. As I can see in the advertising data, the manufacturer specific data comes first and followed by flags and UUID. How to send in order like flags -> UUID -> manufactu...
The memory size of STM32WBCG55 in STM32CubeIDE doesn't match to the datasheet.
Hi, stm.The build analyzer of the CubeIDE showed the full memory size and the usage. When I build my custom project of stm32wb55cg, the size of flash and ram did not match to the datasheet.The below image shows the result.In the datasheet, the flash ...
Updating STM32WB5x\stm32wb5x_BLE_Mac_802_15_4_fw.bin fus firmware is very slow ((p-nucleo-wb55), how we can decrease flashing duration
Flashing stm32wb5x_BLE_Mac_802_15_4_fw.bin (233Kb) in P-Nucleo-wb55 takes about 47.82s through JTAG and SWD, I modified the frequency but I didn't get any improvement.I wonder if there are any configurations or flash methods to decrease flashing dura...
STM32WB55RG HCI Driver communication problems after BLE Stack upgrade to version 1.14.1
Hi community,I have a device with STM32WB55 that has worked successfully with mbed-os for over two years (since the mbed-os 5 version). I decided to do an update of the FUS and STM BLE stack because I was using the old 1.2.0 version and started havin...
Resolved! MemManage fault detected in instruction located at 0x6414AA00.
I'm developing a custom board with STM32WB55.Because there is some error during debugging, I'm trying to solve it.To check what is problem in the microcontroller, I tried Fault Analyzer in the STM32CubeProgrammer and the program found such an error b...
Resolved! BLESTM32WB55 Scan event issue
HiRegarding Scan command.I never get ACI_GAP_PROC_COMPLETE_EVENT after 10 sec. (AN5270 says I should get one)I do get all the updates, but never the complete .Can you check if I need to terminate it myself?
