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 All, I'm currently working on a project where I will have a proxy/Friend Node that will talk with a Low power Node.The proxy node should be able to go on standby when requested and in the condition I would like to obtain the optimal current consum...
Hello,I have a scenario as you can see in the picture below. For creating mesh I am using embedded provisioner (dev1). If I provision dev4, the friendship is automatically established between dev1 and dev4. I want to establish friendship between dev3...
Hello,I bought a nucleo-wl55 card from RS.At the beginning, it worked very well and i started to develop my application.Suddenly today, when i try to run my program, i get an error message : st-link cannot detect a target.And the card become very hot...
Hi,Our device is stm32wb35cc,we use hci command HCI_LE_TRANSMITTER_TEST_V2(0x2034) to trigger direct test mode,and use ACI_HAL_LE_TX_TEST_PACKET_NUMBER(0xfc14) to get transmitted packet number,Recently we noticed that if we do flash erase/write after...
Overview:I have been doing BLE prototyping with an STM32WB55 Nucleo kit (the white PCB, not the USB dongle). I loaded a few different demo projects (BLE Heartbeat, etc) via STM32CubeIDE, but never programmed the wireless stack specifically. I was n...
Hi, I created a new project follow SubGHz_Phy_PingPong project example. Without TCXO configuration, my project work correctly. If I configure TCXO my project can't send and receive "PING" or "PONG". With TCXO configuration the Radio.Random = 0.What w...
Hi all,I am designing a system of microcontrollers for a research project that take RSSI measurements from each other and send the collected data to a connected android device. All of the microcontrollers in the system are flashed with the same or si...
Hello,I want to upgrade my code using BLE OTA in STM32WB55. I followed all the steps that are mention in the reference manual of BLE OTA. but it is not working in FW version 1.13.3. I have also tried the pre build binaries of example code of BLE_p2pS...
Hello, We are facing issue of missing downlinks, say missing 5 out of 30 downlinks, there is only 1 device and 1 gateway on TTN, gateway shows data that it sends downlink, but device unable to get it.If there is fast External Interrupts (use to count...
I'm using FreeRTOS in an STM32WL55 based application that needs to be active only few time per day (3-6).The system need to be in stop mode for most of the time and I have an external line that is connected to the LPTIM and based on this line status ...
