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'm trying to use printf with SWV.I'm using a nucleo-wl55jc1 board (stm32wl55). I have soldered SB8 to connect SWO to stlink.I have made all the config but the it doesn't show any trace.this is my setup:Create an empty STM32 project for the NUCLEO-WL...
Hello,I would like to disable the LPUART in my project to save power consumption. I am programming a point to point network with LoRa modem. My project is based on the ping pong subghz example.Curently, my board consumes around 107 µA in sleep with t...
This uplink frame count increment error frequently occur when we reducing tx duty cycle. Please give me any solution this happen so many times in a day.
I am building ble application on stm32wb and below is the RTC configuration via cubemx.I am trying to implement a scan timeout using the timeserver. Basically, I start a scan procedure and continue scanning until the time-out callback is invoked whic...
Hi,I get GPS time from lorawan network using "DevicetimeReq" command. There is an example how to convert UNIX epoch time to calender time in UM2073 application note. But it uses only second field of system, doesn't benefit from sub-second information...
Anyone can explain me where do the following constants come from and what is their function in the RTC? I am starting my own application and I would like to know if these values suit my own application.
Hello, A corner case has been recently identified with FUS v1.2.0. It is not possible to upgrade back-to-back a wireless firmware with a new version that is exactly one sector bigger than the installed version. This limitation applies only when the r...
I designed my custom board based on STM32WB55CCU6 and I am using an ST-Link programmer for the process (not DUF mode).I am trying to read The FUS version and update FUS.The steps that I am following :1.Delete the existing wireless stack: STM32_Progra...
I designed a custom board with STM32WB55 with a USB connection to update the BLE stack in DFU mode.When I connected the board to my laptop's USB port, it appeared in the device manager and was detected as a USB device, however since yesterday when I ...
Hi,I have a problem when I try to develop a program with STM32IDE for my NUCLEO STM32WB15. I want to use the BLE with a custom template but unfortunately, after launching the program I get a HardFault Error (I guess from the RTC).According to my rese...
