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 everybody,For a proof of concept, I attempted to validate the LoRa modulation by having two B-WL5M-SUBG1 boards exchange ping-pong messages. However, I couldn't manage to exchange data with these boards at a distance greater than 230m in an ope...
We would like to power the VDD33 domain of an STM32WB0 device (STM32WB05KZ) from an external 3.3V source and the other domains from an external 1.8V source. In theory, it should be possible - by supplying 1.8V to VDDSD in SMPS BYPASS mode, or directl...
Hello,I'm working on a BLE Key Fob with 4 buttons operating on a CR2032 coin-cell battery. The goal is that the device sends a "key pressed" data with the status of all the buttons and the battery voltage a short time of period (a couple of seconds),...
When using the NUCLEO-WBA55CG development board and running the BLE_HeartRateFreeRTOS example, I found that the delay time of osDelay is extremely long, nearly 10 times longer than the set delay time. What is the cause of this and are there any solut...
I have problem in stm32cubeIde i want to configure BLE Mesh but there is no option to configure it please suggest me how to do in STM32WBA55
Hello,Sometimes saving to flash takes the devices a couple of seconds.It enters through APP_ZIGBEE_persist_save() -> APP_ZIGBEE_NVM_Write() -> EE_Write -> EE_Transfer -> EE_ReadEl; and takes a while in this function.Occasionally, the device enters th...
Hey,I am trying to make a device which connect to an app using stm32wb15. Everything works properly, but I want to make it so that when the device becomes disconnected, i can use a button to broadcast BLE so that i can connect through an app again. I...
Hello! I'm working on a custom PCB that uses the STM32WB1MMCH6TR module, which was chosen specifically because of its integrated antenna. Unfortunately, with the first prototypes I'm getting extremely poor range with BLE, usually <-80 dBm even just a...
Hello,I have STM32-WBA55CG connect with MEMS sensor. STM32 board will send the messages back to terminal through USART. The WBA55CG is right now connected to stationary power source. It would be nice if someone can give some ideas, how to transform i...
Hello,I'm using WBA55CG Board and i have tried to flash this example STM32WBA Bluetooth® LE – Serial communication - stm32mcu to the STM32. The flashing step is completed, i could connect the board through ST BLE Toolbox on iOS. However there is no s...
