Ask questions and discuss STM32 wireless solutions and their implementation for running Bluetooth LE, Zigbee, LoRaWAN applications.
Dear all, The X-CUBE-MATTER Expansion Package is now available on our official website following this link MATTER - Matter software expansion for STM32Cube - STMicroelectronics It is a reference implementation for the demonstration of Matter on ST...
Please go and visit our wiki pages where you can find a lot of information on our wireless product families (WB, WBA, WL) and the supported protocols: BLE, Zigbee, Thread, Matter, Lora, ... To begin your technical journey, please start from this top ...
Zigbee test using 1xZC and 1xZR.For ZR to join network, the distance to ZC was limit to arround 2m. After join network, the distance ZR message to ZC can be extended to about 20m.Not understand why the join distance so short. Here's my test setup: ...
Hello,I am currently using STM32WLE5CC MCU, which has a great feature of RTC with 32-bit sub-second wakeup counter, But I need a low cost MCU for my other non lorawan project, which also need this "RTC with 32-bit sub-second wakeup counter" feature.P...
Hi! I'm working on STM32WLE5JC micro-controller. Is there any way to write the firmware in such a way that I don't have to send the join request every time the controller wakes up or restarts?I mean when I first time join the network, what are the sp...
I'm trying to make my custom STM32WB55 board.Recently, I succeed to start programming the STM32WB55VGY6TR but the advertisement of custom Bluetooth low energy does not start. I tested programming the Nucleo-WB55 board with the same coding and it was ...
Greetings,what is the recommended frequency deviation parameter for the FSK modulation with 250 kbps bitrate?Or rather what is the dependency of RX sensitivity in relation to the FSK_FDEV parameter?I can see that the limitation is to have the modulat...
Hello everyone,I am now working with LoRaWAN_End_Node on Nucleo-WL55JC1 and I found no place to change configuration such as BW, TX power, Spreading Factor, etc. in this example (Probably, I found at wrong places).Is it possible to change those facto...
Follow Lecture : WB Bluetooth mesh - 7 Lab 1: Creating Bluetooth Low Energy project STM32WBMMG-DKHello, I am a student who recently started the low power Ble project.I bought a nucleo-wb15cc board and am working on the project. After reading this lec...
CubeIDE : 1.7.0CubeMX : 6.3BSP : 1.12.1chip : STM32WB55I'm using the internal RTC of the STM32WB55. When the MCU is running the RTC works normally : the calendar can be set and the time is running correctly. When i shut the MCU power down (but still ...
Hello everybody, I am working with a stm32wb55 and in my application I need to send the microcontroller to sleep for 5 second, wake up, perform some actions and go back to sleep.I send the micro to sleeomode using the function HAL_PWR_EnterSLEEPMode...
Hello,I am trying to develop an application with STM32WB55 that checks the sensor status every 500ms and goes into power saving mode set as STOP2. The datasheet mentions that the wake up time is only about 6us. So I expected the wake up time to be v...
