Resolved! Can't flash my board after following "STM32WB Getting Started Series: Part 5, CubeWB Heart Rate Monitor". What can I do to solve it ?
I followed the series of video "STM32WB Getting Started" with my P-Nucleo-WB55 board. During the 5th video "Heart Rate Monitor", I flashed the BLE_HeartRate project into my board and since this I have this message :"Target no device foundError in ini...
Why does the B-L072Z-LRWAN1 current fluctuate between 2.5mA and 2.9uA when it should be in sleep mode.
I just loaded version 2 of the AT slave firmware on my B-L072Z-LRWAN1 discovery kit and noticed that the current measured over JP3 which heads to the MCU oscillates between 2.5mA and 2.9 uA every 50 milliseconds. When I flashed the device with ol...

i'm using P-NUCLEO-WB55i try to update bootloader using stm32wb wiress stack updater.I saw the link below and set up the hardware for bootloader.https://visualgdb.com/tools/STM32WBUpdater/connecting/When I connected the usb, I could see DFU in FS Mod...
Jitter susceptibility of STM32WL TCXO when using digitally compensated TCXO
In testing my LoRa design at 868 MHz on the STM32WL with a digitally compensated TCXO I witness a significant jump in frequency when (what I assume is) a micro-jump of the TCXO occurs. The specification rate this as maximum 300ppb which equates to w...
How to implement broadcast message on MAC 802.15.4 ?
Hello,I build a network that have some coordinators(FFD) and few nodes(RFD) by using;Dev-kit: STM32WB55 NucleoSW: Mac_802_15_4_FFD (from STM32Cube_FW_WB_1.11.0)I want to send a message that will be received by all nodes and all coordinators nearby. ...

Resolved! HSE optimization
Hi,Using the P NUCLEO WB 55 with STM32WB .Encountered with below code, regarding HSE tuning, in workshop tutorial. A reference was given to An5024.This code does not exist in my example project, BLE Heart Rate RTOS, generated with STM32Cube 6.2.0 , F...
Resolved! Do I have to use an external resistor for the HSE oscillator on STM32WB55 MCU?
Hello,Depending on the datasheet of the STM32WB55 MCU, there is an external resistor for the oscillator circuit. In many Nucleo board schematics, it is not used. The datasheet says that the resistor is to avoid overdriving current. How can I decide t...
