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 have the problem, that my MCU seems to loose its connection to the network quite often (after some minutes or hours usually) and is therefore not usuable.I would like to detect this in my Application and then trigger either a rejoin (if possible...
Hello, I have an STM32WB55 processor. I use BLE. I use FreeRTOS.I call the functions HAL_PWREx_EnterSTOP1Mode or HAL_PWR_EnterSLEEPMode.Before that I call the HAL_SuspendTick function.But somehow I exit WFI. Somehow an interrupt comes but I couldn't ...
Hi, I'm using the LoRaWAN end node example from the stm32cubewl v1.3.0. The board im using is the RAK3172 based on the stm32wle5ccu6 chip. The application i want to build reads data from a modbus using UART and sends it through lorawan. I have assign...
Hi everyone,I am using the LoRaWAN_AT_Slave example code on an STM32WL-based device, and I am operating in OTAA mode with the ChirpStack server to monitor the data. I am successfully sending sensor data to the server at the specified intervals.I have...
Hello, I am planning to develop a 915 MHz LoRaWAN end node using the STM32WLE5C8U6. My goal is to send data from several sensors—such as GNSS, temperature, and accelerometer—directly to a gateway without employing an external MCU. 1- Could you please...
Hello,I would like to use the BLE_p2pServer_ota example with the STM32WBA55CG as a template for a project. Since I do not have an LSE available here, I would like to use the LSI. Which settings (defines) do I have to change?If I use the LSI with 32,0...
Hi, I'm testing a custom STM32WB09TEF7TR board. To communicate with the analog front end, I need to use SPI.However, SPI communication requires 17 us setting time, which means around 60 kHz.This speed is very slow.So, the Initiation of SPI becomes th...
Context:I have succesfully implemented a CDC device in a stm32f205 board 6 months ago.Now im trying to implement the exact same thing in my STM32WB5M discovery board.BLE is already activated and working P2P custom serverUsing CUBEMX 6.3.0FW package S...
Matter software expansion for STM32Cube v1.1.1. When I build 2_Images_SECoreBin on macOS development environment, the build fails probably due to postbuild.sh and prebuild.sh.Please let me know how to fix this.
we are working on STM32WLE5 development.We succeeded to enter Shutdown mode and measured supply current of less then 40nA when operated at 3.0V,but at that time, the VDDRF and VDDPA were not connected (0 volts), meaning we could not test the LoraWan ...
