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 started a Circuit/PCB design with STM32WL55CCU (UFQPN48) to work at 433MHz.I was referred to ST design for low band/Hight power and to AN5457.But I am style missing for some information:What is the PA impedance at 433MHz for UFQPN48 package?In A...
I have a program that requires a 30 second wake up period to feed a watchdog but use as little power a possible. To initiate the LPTIM using an external 32.768kHz watch crystal I am doing this:__HAL_RCC_LPTIM1_CONFIG(RCC_LPTIM1CLKSOURCE_LSE); //LSE L...
Hi,I am current reading the material to develop a LoRa application. My PCB is wicked small, therefore the chip-antennas wont have a good ground plane and therefore bad efficiency.While reading about the RX-path, I stumbled upon AN5457 where in figure...
Whenever I set the SMPS Clock Mux to HSE /4 /2 = 4 I can save the project without errors but whenever I reopen the ioc file I get a warning that there is a clock issue that needs to be fixed. I go into the clock configuration and it's bee reset to H...
Hey,It states on the product page for the STM32WL5MOC that it is certified. In the presentation for the part the FCC logo is under the "Certification" box. Does this mean that the module already has FCC certification? If so, is there a way to view th...
Dear ST,I am trying to configure a simple zigbee centralized network with one coordinator and one endpoint, but I can't manage to correctly configure a rejoin request.As I understand it, a rejoin can be used to join a network as well. As per the docu...
Hey ST Community!I've been exploring the capabilities of the STM32H7B3I-DK development board, specifically its built-in WiFi module with the Inventek ISM43340-M4G-L44-10CF chipset. While I've successfully implemented HTTPS functionality using existin...
Hello, I just came accross the STM32WL series and I was wondering if I can implement a different modulation other than the ones included (FSK, PSK). I need to acquire an analog signal, convert it to digital and then modulate it with a frequency modul...
Good Morning,I am working with an engineer that needs to asses the current based on the states of the STM32WB. Is the simplest approach to use the Nucleo Board with the part and then, reviewing the schematic, place a current meter in line with the j...
Dear St,I'm developing a cluster with a client and server, where I have a client to write on the cluster of the server. I can write with the function ZbZclWriteReq() on the server, but I'm not always successful. When I do the first write, I have succ...
