STM32 MCUs Wireless

Cannot program option bytes nor flash nor registers in STM32wb55. All registers set to 0.

Unable to successfully load BLE firmware because of FUS_IMAGE_NOT_AUTHENTIC so my code is failing in SHCI_C2_BLE_Init()

I have a custom board with an STM32WB55CEU (512K Flash) that is failing to start the BLE stack on CPU2 in the function SHCI_C2_BLE_Init(). I believe it's failing this function because it failed to load the BLE firmware (stm32wb5x_BLE_Stack_full_fw v1...

I am looking for some data about jitter and phase noise for different clock sources including MSI, HSI16, and HSE32 in STM32WLE5/E4xx MCUs. I checked the datasheet and we have a reported jitter number only for MSI clock. How I can get such a data? Thanks

Enhancement: add LmHandler extension for US sub-bands to STM32WL FW package

US sub-bands currently make use of the Hybrid feature selected in the LoRaWAN Cube configuration, and that's a good start, but it would be useful to add a run-time API to select sub-bands, like in the US.Dana

No rule to make target in CubeIDE with a CubeMX Example (STM32WL)

After an export then import (whether in "file system" or "archive file") of a working project, I cannot "build" this project agin after this export/import. While the basic project (before the export and the import i.e. the displacement) works perfect...

STM32CubeWL is based on STM32WL55 MCU. if we need STM32WLE5CC, could you provide any guide document to show how to migrate? thank.

Calibrating the VBAT internal potential divider on an STM32WLE5

I am using the VBAT pin to measure the voltage of my battery, but the readings I am getting through this pin are always off by about 3%. The datasheet (https://www.st.com/resource/en/datasheet/stm32wle5cc.pdf#page=120) claims that there could be +-10...

One-to-Many LoRa connection

Hi!Can someone help me to clear one moment in using LoRa.Let's say I have one RF remote control, which is pointed to 4-5 remote devices.How can my remote control distinguish replies from these 5 remote devices?Sorry if this is a dummy question. I'm n...
