Resolved! THREAD: Duplicate IPv6 address
Dear ST Support Team,I am using STM32WB55 with firmware stm32wb5x_BLE_Thread_dynamic_fw.bin release V1.23 and application based on samples in STM32CubeFW. I flashed two devices and set both devices:OT_LinkMode.mRxOnWhenIdle = 1U;OT_LinkMode.mDeviceTy...
how to synchronize several BLE devices
HiI have 6 BLE peripherals with some ADC's. I need to make sure that all 6 devices sample at the same time. The Accurracy needs to be below 500 micro seconds. Is there a way to synchronise devices via BLE stack ?Thx
STM32WB55CEU6 and BLE stack programming
Dear community, On my board, a STM32WB55CEU6. My aim is to add the DFU BLE possibility for code update.On the first picture, you will see mu CUbeProgrammer Interface.After click on "Read FUS infos", i'm able to read status.The FUS is ok, but the stac...
STM32WB5MMG with Full BLE stack / Power Consumption
Hi All,I'm currently using an STM32WB5MMG on my project and I'm struggling to reach the expected power consumption.Please note one known error on the PCB: the RF_OUT and ANT_IN pins, which should be connected to GND according to the datasheet/guideli...
LoRaWAN_End_Node_FreeRTOS: 20 to 25 minutes delay every data send
i am using LoRaWAN_End_Node_FreeRTOS in STM32WL55JCIX in that for send the data i used APP_TX_DUTYCYCLE and set 43200000(12 hours) for send data to gateway there is delay getting of 20 to 25 minutes every data send is there any solution for that ???
Internal RTC Alarm Issues
We are currently developing two LoRaWAN-based products using STM32WL55J (battery powered and Mains AC). Both devices are designed to sample sensor data every 30 seconds and transmit it according to a defined daily duty cycle.However, we are facing ch...
STM32 Stop Mode 2 not entering
Hello everyone,I’m working on a project using the STM32WB55RG microcontroller with FreeRTOS, and I’m trying to put the MCU into STOP Mode 2. The system is supposed to wake up regularly using the RTC.I’m using LL libraries to configure the power regis...
