[STM32WB55] Launch app after FUS/BLE stack update without power cycling

Hi,I am working with a STM32WB55 MCU connected using a STLINK probe (SWD).In the flashing flow, I use STM32_Programmer_CLI to erase the device, put it in FUS mode, update the FUS, update the BLE stack image, and then flash the app image.One thing I r...

STM32WL54CCU6 and STM32WLE5CBU6: Receiver Sensitivity Data

Hi,I am evaluating 2 MCUs (STM32WL54CCU6 and STM32WLE5CBU6) for our new design. I would like to get the receiver sensitivity at the following condition: 2-(G)FSK, BER <1%, 200kbps, 50kHz FDA at 915 MHz, which datasheet don't have. When you have a cha...

Issues about STM32WB

HiWe develop a project on the STM32WB5MMG MCU. We have 2 issues:1. How can we get the actual MTU after the negotiation with the remote client (probably a smartphone) ? We want to support all kind of smartphones including those with small MTU. Do we h...

Resolved! STM32WB5MMG power removed while updating FUS

During testing to see what happens if power is interrupted during various parts of firmware update, I removed power from my test board while updating FUS. Now, when I connect via SWD using STM32CubeProgrammer, it shows the following: When I try to up...

Most pragmatic way to use LoRaWAN middleware not in periodic, but event driven operation

I have a burst sampling MCU application that wakes up via interrupt, samples, and should now signal a backend through LoRaWANThe CubeMX skeleton spins up a whole system with sequencer, power mode management etc, which is - did I get this right? - bu...

Single- / Dual-Core with STM32WLx5: Are both cores connected to SUBGHZ peripherial?

I am confused because I thought I have read somewhere that on the STM32WL55JC, only the M0+ Core is connected to the RF part and therefore M4 core normally hosts app code, M0+ core the RF part.In the examples I have seen for the Nucleo WL55JC there a...

Resolved! How to use PA15 (JTDI) as a GPIO

On a custom board, the RED_LED is connected to PA15, which is pulled-up by default (JTDI).The pin has been set to Push-Pull Output GPIO in CubeMX and is initialized to 0.The STM32WB55CGUx was experiencing random resets, until this particular IO was s...

Resolved! STMBW55 LPTIM1 PWM Mode Continuous is working but no interrupt

Attached is the IOC setup for simple continuous PWM Mode from LPTIM1 from STM32BW55 (all Cube IDE/MX updated with the library, etc).. RB2 showing the waveform as per Peroid and Pulse width (from 64MHz clock input) but I get no interrupt (enabled by I...

stm32wle5cc autoregister

HiI need to know that how can i create thousand amount of binary or hex file for different keys during mass production. I use custom firmaware, sdk v.1.0 for development and i wrote manually keys of each device.

Resolved! STM32WL store NVM context Lorawan

Hi, I need some help trying to undestand this operation in Lorawan_end_node example projectnvm_size = ( ( sizeof( LoRaMacNvmData_t ) + 7 ) & ~0x07 ); in the code below:Maybe it is so simple, but i thought that it would be something like that nvm_siz...
