STM32WB BLE direct test mode and flash erase/write?
Hi,Our device is stm32wb35cc,we use hci command HCI_LE_TRANSMITTER_TEST_V2(0x2034) to trigger direct test mode,and use ACI_HAL_LE_TX_TEST_PACKET_NUMBER(0xfc14) to get transmitted packet number,Recently we noticed that if we do flash erase/write after...
Factory FUS + Wireless Stack
Overview:I have been doing BLE prototyping with an STM32WB55 Nucleo kit (the white PCB, not the USB dongle). I loaded a few different demo projects (BLE Heartbeat, etc) via STM32CubeIDE, but never programmed the wireless stack specifically. I was n...
How to configure TCXO for SubGHz_Phy_PingPong correctly?
Hi, I created a new project follow SubGHz_Phy_PingPong project example. Without TCXO configuration, my project work correctly. If I configure TCXO my project can't send and receive "PING" or "PONG". With TCXO configuration the Radio.Random = 0.What w...
How to simultaneously scan and advertise during a connection for STM32WB55
Hi all,I am designing a system of microcontrollers for a research project that take RSSI measurements from each other and send the collected data to a connected android device. All of the microcontrollers in the system are flashed with the same or si...

Hello,I want to upgrade my code using BLE OTA in STM32WB55. I followed all the steps that are mention in the reference manual of BLE OTA. but it is not working in FW version 1.13.3. I have also tried the pre build binaries of example code of BLE_p2pS...
STM32WLE5CC miss Lorawan Downlinks
Hello, We are facing issue of missing downlinks, say missing 5 out of 30 downlinks, there is only 1 device and 1 gateway on TTN, gateway shows data that it sends downlink, but device unable to get it.If there is fast External Interrupts (use to count...
Working with FreeRTOS in low power tickless mode for long stop periods
I'm using FreeRTOS in an STM32WL55 based application that needs to be active only few time per day (3-6).The system need to be in stop mode for most of the time and I have an external line that is connected to the LPTIM and based on this line status ...
Resolved! Is the BLE_OTA application which is written for stack V1.8 compatible with stack 1.13.0?
Hi everyone, I have the STM32WB55 MCU. The Bluetooth stack is V1.13.0. I know it has its own BLE_Ota application for this version but I wonder if it's possible to use the BLE_Ota application which is written for V1.8 on stack V1.13. So, Is the BLE_OT...

Resolved! porting project from STM32WL55JC (3.3V) to STM32WLE5CC (1.18V) - all running but no RF signal on Tx
Hi all,I have to port a working LoRa project from STM32WL55JC (3.3V) to STM32WLE5CC. First besides the JC (BGA) has more pins thatn the E5CC (QFN), anything else should be the same (expect maiy EXTI which te project does not use).Now my the issue: Th...
