Split from Interfacing external sensors with I-CUBE-LRWAN End Node STM32L476RG based Library.Hi! Could you please share how you interfaced the RFM95 with the STM32L476RG using the I-CUBE-LRWAN library? I’m new to using the I-CUBE-LRWAN library and wo...

The callback is not executed when HW_TS_Start is called

Using STM32CubeWB v1.23.0, I am running the hardware timer in the following order:HW_TS_InitHW_TS_CreateHW_TS_StartHowever, despite this, the callback registered at the time of Create is not executed after the set time.What could be the problem?

the antenna area PCB artwork design for the STM32WB1MMC and STM32WB5MMG modules

Hello,I have a question regarding the antenna area PCB artwork design for the STM32WB1MMC and STM32WB5MMG modules.In the STM32WB5MMG datasheet, it is recommended to:- place the module at the edge of the PCB,- fill the right-hand side of the module wi...

STM32WB55 CRC Failure in Write Response (Stack 1.23.0)

We are seeing an issue where the STM32WB55 module is failing to send a valid write response. The write response is attempted but based on the packet logs, the CRC is failing. This results in the central (app running on Android) forcing a disconnect...

Resolved! Achieving Low-Power Modes (Standby/Shutdown) with STM32WB Zigbee Application

Hello STM Community, I’ve successfully implemented a Zigbee application on the STM32WB series MCU that leverages the Low Power Manager to enter Standby or Shutdown modes, as detailed in AN5289 section 4.6. The application note highlights the Low Powe...

PWM input on STM32WB5MMG

Hi, I'm planning to use a STM32WB5MMG for a custom board. For this application, I need to measure the frequencies and the duty cycles of three different PWM signals. I know that there is the PWM Input mode of some TIM. However, I verify that there ar...

Resolved! STM32WBA BLE Data Throughput example : throughput optimization

Hello everyone,I'm currently working with the STM32WBA65RI Nucleo board.For my upcoming application, I require a stable BLE throughput of over 800 kbps. However, using the provided example, I can only achieve around 600 kbps.So far:I'm using an MTU o...

Resolved! stm32wb FUS footer has empty word between magic word and version

Hi.I'm working on stm32wb for some time, handling CPU2 updates of BLE stack application.Lately, version 1.23 was published with new FUS version, so I tried updating it with my application running on user flash. I searched for the magic word but I fou...

Resolved! Unexpected Behavior with RTC ALARM_A in LowPoer Mode on STM32WB55

Hello everyone,I’m working with an STM32WB55 microcontroller with BLE stack. I use also low-power modes in my app. Before entering a low-power mode, I set an RTC ALARM_A to wake the system up at a specific time. The device then enters either Sleep or...

STM32WB5MMGH6TR and STM32WL5MOC on the same board

Hi,I want to integrate on the same PCB both a STM32WB5MMGH6TR and a STM32WL5MOC. Are there any issue in terms of RF interference? Are there any shielding recommendations to avoid problems while both modules are transmitting?ThanksMatteo
