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 using the STM32WB55, with STM32CubeWB V1.14.1 & `stm32wb5x_BLE_Stack_full_fw.bin` V1.14.1.Looking in `app_debug.c`, I can configure `aGpioConfigList[]` and `aRfConfigList[]`, which allows for CPU2 to toggle a GPIO pin based on various events.I ca...
Some strange behavior is happening when debugging our firmware through STM32CubeIDE, where it erases the option bytes upon flashing the firmware (0xFF @ 0x1FFF8000 onwards). The debugging session still launches ok and the firmware appears to be flash...
Document AN5554 Rev4(LoRaWAN® firmware update over the air with STM32CubeW) mentions, on page 60, about file fuota_automation.py. I can not find this file in software package for STM32WL. Is this file accessible to download?
Hello, I use a Nucleo WB55 and I would like to receive temperature data from MAX31855. The protocol used is SPI. 1) ConnectionsFirstly I tested the MAX31855 with an Arduino and I managed to get data. I used the same MAX31855 and double-checked the wi...
I am using STM32CubeWL PingPong application. It is consuming 370uA in stop 2 mode. I need help to reduce it to 2uA(As specified in datasheet). I have initialized all unused GPIOs as analog inputs with no pull up. Still the module consumes 370uA in st...
The previous developer developed a device based on STM32wb55. We were produced an anower such device and flashed with the same firmware and wireless stack version 1.14.0. The new device communicates with the our test software, but loses communication...
In the datasheet of the STM32WB5MMG Module is writtenThe module antenna must be installed to meet the RF exposure compliance separation distance of “20 cm�? and any additional testing and authorization processes as required.in the sections FCC and IS...
I have some question related to the BLE stack code. Specifically regarding GAP operation.My device is the peripheral.On first connection to my device from peer :How long can a 'connection procedure' take. From when the stack is receiving a connection...
What is the meaning of the time data in last 4 columns in table 3 ("Stop 2 versus Standby gain, function of Tx interval time") and 4 ("Stop 1 versus Stop 2 gain, function of Tx interval time") of AN5568? What is the meaning of different percentages (...
Hi everybody,I have to problem with LoRaWan EU868 certify in Ukraine, specifically as follows:I am using ABZ module as CMWX1ZZABZ-091 to develop product, and I set ABZ module such as:+ firmware based on source code en.i-cube lrwan v1.3.0+ used Lora m...
