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!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 ...
I'm designing power supply part of STM32WB55 microcontroller.I'll use a Li-ion battery for power supply of STM32WB55 microcontroller.As we know, the microcontroller requires 3.3 V maximum but Li-ion battery can generate maximum 4.2 V. So, I'll use in...
I have created this easy project for the RAK3172 based on the LoRaWAN end node skeleton (myIoTopenTech/TiposDeDispositivos/TTNMAD_SOUND/STM32CUBEIDE/ttnmad_noise/) available on GITHUB.The program works properly joining to The Things Network using OTA...
Hello,I'm doing a new board bring-up and following the document AN5503 (https://www.st.com/resource/en/application_note/an5503-bringing-up-the-bluenrglp-bluenrglps-devices-stmicroelectronics.pdf)At chapter 4 (HS_Startup_time) I use the example firmwa...
We have implemented BLE application on STM32WB5MMGH. I see that some of the BLE packets are getting lost in transit. The peripheral and the master are in very close proximity. I understand that packets can get lost depending on environment but my que...
