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 ...
When a gpio detects an external event (triggered by the falling edge), the server sends a 15 byte notification. I use stm32wb55rgv6 to collect ADS1299 (ADC) data. The sampling rate is 1K (that is, 1000 falling edge triggers). The server should se...
What are the reasons that affect the speed of BLE server notification? I've been testing for a day and I found that I'm sending a notification of 15 bytes every 5ms and I don't know how to change it.My requirement is to send a notification of 15 byte...
The following figure is the load and corresponding interval of my single notification：I think the interval is too long.I read AN5289 7.6.5 how to maximize data throughput, but I can't find the macro parameters Min_CE_Length and Max_CE_Lengtht, and I...
HelloI developed prototype of wearable device using STM32WBMMG, and planning to acquire FCC certification.STM32WB5MMG already has FCC ID; YCP-STM32WB5M001; however, it is the certification of the chip itself.When mounted any kind of devices(PCBs ...
HI i have ULS24 light sensor with SPI communication protocol which i want to connect to stm32wb55rg board and use it BLE support to connect PC host. PC application will pair these devices and i will get access to control light sensor. please suggest ...
Just trying to figure out the max size I can pass to the write function.According to AN5289 :Write long distant value aci_gatt_write_long_char_value(conn_handle, RxCharHandle,offset, chunk_size, (&payload)+offset) Max data write length is 243 bytes.I...
Hello,I use a stm32WB15 MCU in shutdown mode with a wake up by the wake up pin PA0 (System wake-up 1).Everything works fine with the polarity "High". I use the HAL function "HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1_HIGH)".But with the polarity "Low" a...
