STM32WB1MMCH OTP

STM32WB1MMCH：Can other values be written again after the otp area is written to 0xFF

Resolved! VDD_TCXO not used at STM2WLE5JCI6

Hi,We are using the STM32WLE5JCI6.In our design, the TCXO (HSE) is powered directly by the 3.3 V on-board power supply, and the VDD_TCXO pin is left unconnected. Is this acceptable?Should we avoid using the Set_TcxoMode command in this case?Thanks fo...

STM32WB55CGU6 Custom Board, Not able to connect with STM32CubeProgrammer

Hello All,We have made a custom board design with STM32WB55CGU6.But we are struggling to detect the device with STM32CubeProgrammer. I am using P-NUCLEO-WB55's ST-LINK connection to detect and flash the M0 Firmware with STM32CubeProgrammer.SWDIO, SWC...

STM32WB: CPU2 enters STOP with PESD=1 after Adv_Cancel, blocking CPU1 flash writes

Hello,I’m working on a custom board with STM32WB15CC, dual-core mode with BLE stack.I noticed an issue related to PESD (Program/Erase Suspend) when CPU2 enters STOP mode.In my application, I call Adv_Cancel(); and this makes CPU2 enter STOP autonomou...

Resolved! stm32wl33, IQDump

I’m working with the NUCLEO-WL33CC2 development board and running ST’s CLI demonstration firmware. My goal is to retrieve raw baseband I/Q samples, but I can’t get any I/Q output using the demonstrator commands, specifically IQDump. If you’ve succes...

STM32WL55JC1 LoRa EndNode example not working when RTC Bin Mode set to "Free running BCD calender and binary mode"

Hi,currently I am working with the NUCLEO-WL55JC1, using the STM32Cube FW_WL V1.3.0 and the LoRaWAN_End_Node example as base.My target is to keep the LoRa stack working as it is on the example, but also to use the RTC to store the current date and ti...

Using RTC with LoRa

Hello guys!I'm working with STM32WL series using the LoRa application, for that the RTC must be in binary mode.However, I need the calendar and timestamp for my project, which implies that I need to use BCD mode.I'm aware that the RTC3 has the mixed ...

BLE connection fails when project is generated for IAR (works with CubeIDE) on NUCLEO-WBA55CG

I am facing an issue with BLE connection on the NUCLEO-WBA55CG board.Using the same .ioc file:When I generate the code for STM32CubeIDE, the project builds and runs fine, and I can connect to the device successfully using the ST BLE Toolbox app.But w...

NUCLEO WL55JC1 - No device found on target on STM32CubeIDE

Hi,I recently bought two NUCLEO-WL55JC1 boards and was testing the SubGHz_Phy_PingPong example to establish communication between them. Everything was working fine at first, but at some point (I’m not sure if I changed anything), one of the boards st...

LoRaWAN FUOTA

Good day I am having many troubles with implementing FUOTA on my Dev kit. Firstly, I have downloaded the STM32Cube_FW_WL_V1.3.1 firmware. When i edit the script files to build using the latest cube ide (1.19.0) the build fails with many errors. I the...
