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 ...
Hi,I work with STEVAL-DB012VA, anf WISE-Studio over Linux. Starting from the peripheral exemple, I am trying to output a sequence of bits over GPIOB at a specific rate. To do this I am programming the DMA to transfert data from a buffer in memory to ...
We have a device which connects to two other devices as a central, and also is connected to by a third device (Mobile Phone) as a peripheral.When updating the Bluetooth firmware binary from version 1.20.0 to 1.21.0 we have started experiencing discon...
Hi,Using Wise studio Version: 1.3.1_R Build id: 2023_05 on Linux with the STEVAL-IDB012V1 (BlueRNG-LPS dev. kit). I discovered that my instructions to write values in the timer registers have no effect. I found it by tracing the program while watchin...
We are experiencing an issue with poor RSSI values on our STM32WB55 based custom board. We are normally running the extended ble stack and with only 3 feet between the windows PC and the STM32WB55 board were at RSSI values around -85. When I switch ...
I am developing a custom board based on the MB1389E reference design, using the STM32WL55JC microcontroller. I have designed my schematic using KiCad and attached the PDF version for review.I would appreciate feedback on the following points:Oscillat...
Hello, I'm trying to implement a custom BLE Client on a P-Nucleo-WB55 board. The ST P2p_client example runs fine on the board and I could add some traces and do little modifications in it before trying to start my project from scratch with CubeMX. It...
Initially flashed the device with a custom code from and it worked fine, the flashed device ran for several days in line power even after multiple power cuts. But one day it stopped trying to join at all. I have used an external RTC to generate alarm...
Hello, I have a STM32WBA55G-DK1 board, and i'm trying to build the example code for the Unicast server (BLE_Audio_TMAP_Central example project). I'm importing it using the GUI (new project, example, then i select the example). I haven't modified any...
Hi all,I'm currently working on a project involving bidirectional communication (TX and RX), and I'm encountering an issue with the RTC initialization.The problem is that my code often gets stuck in the MX_RTC_Init() function. Interestingly, it works...
When temperature below -15℃ , STM32WLE5CCU6 UART can't receive any data from uart, But it can send data out from UART.,and The LoRa Unit worked well,It seems the TXCO is working. What's the problem? How can solve this problem?
