Stack firmware flash via DFU fails on STM32WB55CCU6

So we update the FUS following the steps specificed in the release note, the process went ok and the FSU was upgradedUSB speed : Full Speed (12MBit/s) Manuf. ID : STMicroelectronics Product ID : DFU in FS Mode SN : 206936933136 FW versi...

I would like to establish secure connection between nucleo stm32wb55 and mobile phone

In application note AN5289 page 35 it is written that you need to wait for the connection to be established and then call aci_gap_set_pairing_req(). I call this function when connection established event happens, but when I do this return status is 0...

Dongle does not show up as COM Port using BLE_TransparentModeVCP_reference.hex

I have WB55 Dongle board that someone may have programmed previously. I am trying to start it fresh and make sure it is up to date using all files from  from STM32Cube_FW_WB_V1.2.0I followed the procedure to install new FUS and BLE Stack:STM32_Progr...

For flash memory which only burns STM32WB55CGU6 series chips, one sector is locked and cannot be read or written. According to the chip manuals, there are errors in mass erase and programming. How to solve it?

The STM32WB55xx devices embed an Arm ®(a) CPU1 Cortex ® -M4 core.I use this chip manual.I operate strictly according to the chip manual, but all of them have errors in reading, writing and erasing a sector.the flash meomory address range:​0x0800 000-...

Power consumption by STM32WB55RE

Hi Sir/Madam,Here i need calculate the current required to operate the STM32WB55REvx. I downloaded the datasheet of this MCU. In the datasheet should i need to consider the operating conditions or absolute characteristics to calculate the current re...

The Flash of STM32WB55CGU6 Chip Can't Read and Write Normally，A sector is protected by CPU2. CPU1 can not access this area normally. How to switch to CPU2 to read and write this area through DWG or other methods?

FLASH address: 0x0800 0000~0x080F 5FFF, CPU1 (cortex-M4) can read and write to its normal access, address 0x080F 6000~0x080F FFFF is protected by CPU2 （cortex-M0）and read and write.

STM32WB55 Nucleo UART Example - unknown data format on hyper terminal

Hi,I am a new to STM32WB55 Nucleo and have just started to understand it from the examples provided by the ST. In this process, I have observed unknown data format on hyper terminal. i tried with different baudrates and all the available UART library...

I have a B-L072Z-LRWAN1 development board. I am learning the basics of Lora modules and can someone help me out by providing links for any tutorials. I also need to know how to connect B-L072Z device to LoRa network without a gateway?
