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! Examples in the STM32CubeWB repository set LSE_TIMEOUT_VALUE to five seconds after calling LL_RCC_LSE_Enable(). Why so long? Is this addressed anywhere in any of the hardware documentation?

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?

Board based on STM32WB55. My application program doesn't start when powered on. I need to connect and disconnect the board to STM32cube Prg to start execution. Option bytes settings: nBOOT0 = 1 nBOOT1 = 1 nSWBOOT0 = 0 BOOT0 pin floating.

Resolved! Discovery of specific CCDA characteristic descriptors

Please support on following:I am using the STM32WB55 as a BLE client (central).As I understand there are several types of descriptors.How do I know the characteristic descriptor I discovered is a Client Characteristic Configuration Descriptor(CCDA), ...

Is there an example for a long characteristic write procedure?

Using STM32WB55 as a central. My goal is to write a slave attribute of size 512 bytes.I am trying to use an 'aci_gatt_write_long_char_value' to do that.Do I need to break the message to chunks or does 'aci_gatt_write_long_char_value' takes care of t...

STM32WB55RGV6 (BLE notificaiton stuck) I want to notify data from ble server(my own board) to ble client (usb dongle).

Connection interval: 10ms, notify payload: 240 bytes. The usb dongle will output some data and then get stuck.Connection interval: 20ms, notify payload: 240 bytes. The usb dongle will output more data and then get stuck.Connection interval: 50ms, no...
