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 ...
STM32WB.V11.1function: aci_gatt_add_service In the function we copy the Service_UUID struct to buffer according to size.UUID can be either a short 2 BYTES or long array of 16 BYTES.Issue: In case it is 16 BYTES, It looks to be...
My question is about STM32WB series. I have documentation and examples, but it's still not so good. Its very complicated topic(for me). I want to build simple tiangulation navi system based on BLE signal strength.Yes, i have example for STM32WB, but ...
What is the production process (nm) of the STM32WL MCU's ? We are looking at designing a system that will have to operate in a possible radiation encvironment and the nm size of the process will have a bearing on this.
Hi, I have a Nucleo-wl55jc2 (US Low Band 433 Mhz) Would it be possible to remove the RF filters so I can run it on high frequences (EU 868 Mhz) ? Thanks Olivier
I had STM32WB55CGU7 chips with original factory FUS version 0.5.3. I upgraded it to version 1.0.1 successfully, then I tried to upgrade to latest released version 1.0.2, but I get "Error: Firmware not authentic!"
Hi all,I am trying to use I2C DMA as Master and UART DMAMy code isvoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ if (c == 1) { HAL_UART_Transmit_DMA(&huart2, (uint8_t *)b, 8); } else { /* I2C Transmit code */ } c = 1 - c;...
Hi all,I am developing an application on the STM32WLE5CC based on the existing Nulceo boards for the JC part. First, the BoM provided for the JC reference is completely incorrect, it doesn't match the RF network design note, it's own schematic or the...
Hi there,In short I am trying to use the Nucleo-68 board to scan for Cadence Sensor devices with UUID 0x1816 which I've managed successfully. I get a list of all available devices and their addresses (double checked against a report generated through...
Hello!In my app there are the master (stm32wb55) and up to three slaves (stm32wb55 too). In addition to this I need to scan the air permanently. At some point the ble stack of the central stops responding. It means that it becomes impossible to start...
I need to advertise sensor values continuously
