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 ...
I am configuring a dual-CPU project for the STM32WL55JC in CubeMX. This microcontroller has two CPUs: a Cortex M4 and a Cortex M0+. CubeMX lets users select the CPU that each peripheral is bound to. As illustrated in the image at the bottom of this p...
Hi!If I look at the datasheet of STM32WL31xx, I find Table 34. PA impedance which tells e.g. an optimum load impedance of 32 Ω // 16 nH in line 5 (high power, 868MHz) This STM32WL31xx is (according to the datasheet) available in VFQFPN32 and VFQFPN48...
Hello, I'm having troubles building the two projects of the STM32 Nucleo WL55JC1 belonging to the LoRaWAN End Node DualCore Example under Linux (Ubuntu 24.04). It works on Windows 11, though.Until now I have all projects developed on Linux, this is m...
Hello ST Community,I am currently designing a board based on the STM32WL55 and I am aiming to optimize the BOM by utilizing the MCU's internal programmable high-speed capacitors, avoiding external load capacitors for the 32 MHz HSE.I am referencing A...
Hi, In the STM32WL5MOC datasheet I can find the 32MHz TXCO HSE accurancy, but not the LSE 32kHz RTC clock accuracy. Could someone look into this and provide the min/max values similar to TXCO characteristics in Table 10? Best Regards,Dave
Hello ST Community,I am working with the NUCLEO-WL55JC1 and the official Sigfox_PushButton example.When running the application, the firmware consistently fails during EEPROM emulation initialization. The execution enters E2P_Init() and stops very ea...
According to BLE spec, whitelisting is not related to paired or bonded devices. Our application uses the advertisement and scanning for sensor beaconing application. STM32WB55 is not able to scan the interested sensors by whitelisting. STM32WB is not...
Hello all,Anyone successfully implemented the Standby Mode for STM32WBA52/55? I am struggling going thru the examples and I wouldn't be able to enter the standby mode level. My board still consume about 70mA when I enter the standby mode. From the...
I have just received 2 NUCLEO-WL55JC1. Upon connecting either one of them via I see The Red (main power) and green LEDs on. The other thre are flashing alternatively (red, orange, blue). I haven't changed the default jumper settings.The following deb...
Hi, team I previously worked with a SWB (dual core) microcontroller, and I was able to obtain the stack version using the SHCI_GetWirelessFwInfo function. Now, I am working with a SWBA (single core) but I was unable to find an equivalent function to ...
