Custom radio stack on STM32WB55

Is it possible to run a custom radio stack on M4 core of STM32WB processor without using M0 core ? If yes, where can I find the manual to read about accessing radio peripherals from CPU1

Resolved! STM32WB Multi-channel ADC with DMA, buffer sequence issue

Hello geeks..Hope all are doing well I'm using multi channel ADC with STM32WB having DMA activated My issue is, every time when i perform the power ON reset, at the same time the channel sequence getting change! It means, the conversion buffer in HAL...

Resolved! STM32WL Minimal RF circuit for LoRaWAN endnode

hey there! I'm planning to design my own PCB based on the STM32WL55 (900MHz range) and I have the NUCLEO reference design to look at, but find that here's a lot of RF paths in there, and I just want to know if there's any discussion anywhere on how m...

Resolved! SubGhz_Phy_Per example is not working

Hello,I have two NUCLEO_WL55JC2 boards. I am starting with SubGhz_Phy_Per example. One of board is Tx and other is Rx as mentioned readme.txt in project files.Rx board's red led is blinking that means the board does not receive any signal. My jumpers...

suggest alternate ICs for STM32WB55CG and STM32L476RG

Hello, I am currently working on two projects and the firmware is tested and verified on two mcus ( STM32L476RG and STM32WB55CG). I would like to consider different MCUs where the code can run without changing the code. I know if I consider the ICs f...

What is the size of an entry Serial Wire Viewer (SWV) packet?

I am using Serial Wire Debug (SWD) to trace some debug information while using the STM32WB55CGU6U MCU. Based on UM2609, the default maximum size of the SWV trace buffer on a PC = 2,000,000 packets. This buffer is stored in the heap of the STM32CubeID...

Documentation/Ressources for BLE "Custom Template" CubeMX

I'm working on a mobile project based on the STM32WB5MMG.First, we bought a P-NUCLEO-WB55 and had a look at some of the example projects.After a good experience with the Nucleo board, we decided to build HW around the controller.Now the HW is working...

STM32WB55 Current consumption at Vdd=1.8v

The datasheet only shows the current of the STM32WB55 at 3.3V; what happens at 1.8V? In particular: how is the radio section affected by the voltage drop? Does the current drawn in TX and RX remain the same even at 1.8V? (Rx 4.5 mA / Tx at 0 dBm 5.2...

BLE_AT_Client example requires BLE_AT_Server firmware

STM32Cube/Example/BLE_AT_Client/readme.html requirement:This example requires to have STM32WB5M module flashed with latest BLE_AT_Server application from STM32CubeWB package.I downloaded stm32cubewb_v1-12-0 and patch-cubewb_v1-12-1 but these zips do ...
