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 ...
Hello, I'd like to use the STM32WLE5 in an upcoming design. Looking at the datasheet, I noticed the recommendation for the BGA package is to have the stencil opening larger than the pad diameter, instead matching the ball diameter . To me this seem...
Hi all,I’m testing MP3 playback on a Nucleo-WB55RG.Setup:SD card via FATFSHelix MP3 decoder (libhelix-mp3)PCM out via SAI1_A (I²S) → external DACDMA in circular mode, 2× half-buffer callbacksWhat works:A test sine wave buffer played via SAI+DMA works...
I am trying to read GNSS data using B-L072Z-LRWAN1 and GPS module. I installed FP-ATR-LORA1 and wrote the project to my B-L072Z-LRWAN1 and viewed it with Teraterm, the following error message appeared."Accelerometer NOT initialized"I don't use an acc...
Hello,I am working on a project with STM32 + BlueNRG-M2SP/M2SA and using a custom mobile app to connect over BLE.Here is my setup:The BlueNRG-M2SP/M2SA IC module is configured as a Peripheral (Server) with my stm32l0 mcu.The mobile app scans, finds...
I have previously worked on a BLE-based application that required an external antenna. Based on the use case, I selected the STM32WB1MMC module, which, according to its datasheet, supports external antenna connections. I designed the schematic accord...
Hello,I am working on STM32WB5MM custom hardware and trying to implement deep sleep mode using RTC wakeup interrupt. What I want to achieve:MCU should stay active for ~30 seconds after reset.Then enter deep sleep / STOP2 mode.Wake up automatically ev...
Hi there, I have an B-WL5M-SUBG1 evaluation board which uses the STM32WL5M module.I am having problems with the STM32 receiving a message I am sending it from my laptop via python. I connect between the stm32 and the laptop via an RS422/485 converter...
Hi,We are using the STM32WB5 series. We have implemented a FOTA mechanism to update the BLE Stack and the FUS (both separately).We have noticed a new version of the FUS (2.0.0), which, to our understanding, is not backward compatible with older versi...
Hi,I want to create device, based on STM32WB09, with BLE and battery power. I get sample from CUBE and turn on CFG_FULL_LOW_POWER and CFG_LPM_SUPPORTED. It works, between BLE events MCU work in Deepsleep mode, but i need scheduller:1) Deepsleep2) wak...
Hi,I’m working on STM32WLE5 module for storing values in EEPROM. I want to use the last page of flash for storing configuration values of lora.I have used EE library from GITHUB which uses HAL functions.I followed 2 sequences for writing into flash:E...
