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 ...
Can anyone confirm if it is okay to supply the RF switch directly from a general purpose output of the STM32WL? This way I could control when the switch is working or when the antenna is isolated (off) from the circuit.I see in the datasheet for the ...
CPU1 should only be used to initialize the System, boot CPU2 and then go in Standby permanently. The CPU2 should be programmed to read sensor data for a few minutes and then also go in Standby Mode.When the whole system is in Standby mode, it should ...
The STM32WB55 microcontroller have SMPS internally. Can I use it to convert AC power to DC power for the microcontroller? If possible, I want to supply RF inductive charging power directly to the microcontroller.
Hello!We are developing device on STM32WB55 MCU along with mobile app companion. We use stm32wb5x_BLE_Stack_light_fw. The MCU works as Peripheral, mobile app - as Central.In our firmware we use internal FLASH to store some configurations. Our applica...
I'm developing STM32WB55VQ power system but I wonder the microcontroller automatically use battery power or not when Vdd is cut. Is there anybody can explain this?
Hello,From 1.13.0 to 1.13.3, the command ACI_HAL_TONE_START was removed (get Unknown command return). The release note indicates that some HCI commands were removed not ACI commands.Is it an error or should we prepare to move to the full extended sta...
Currently, we are using the STM32WLE5CC MCU.Some MCUs do not operate normally when the same firmware is inserted into several MCUs. (Abnormal current, delays in Uart log output, RF is not transmitted)If a higher voltage (4.4V) than the MAX operating ...
