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 ...
If I write to address 0, it prevents from entering shutdown mode.The vector table is relocated to code.As far as I understand, writing to address 0 in this case is not illegal. For sure it does not generates a fault.The following code enters shutdown...
Hi, I would like to try nucleo-WL55 in LoRa Node with Quatz and see temperature influence in RF signal.So I have unsolder R2, and solder R39/R40. But now LoRaWAN_AT_Slave does not work anymore, even if I change TCXO to Quartz in .ioc file. I can see ...
Hi everybody!Working on Martian Robot développed by VittaScience, I need to read values coming from 5 blackline sensors to the ADC of the wb55.I tried to analogRead() the pin but nothing...Some ideas? Thanks!
I am currently trying to read the value from a characteristic after detecting that the user has written to it. I am calling aci_gatt_read_char_value() which is returning 0 (BLE success). From here I am expecting an event which triggers the aci_att_r...
Voice is heard through the codec chip, but the noise is severe.There is no noise when you listen to the voice from the PC through the USB output.I don't know if the SAI setting on the Central is wrong or the codec chip setting is wrong. If you playba...
It looks as if the RNG is made unavailable to the M4 when the M0 has booted the BLE stack. This looks to be true because I can initialize and use the RNG before starting the BLE stack. Once I launch C2, the RNG registers read as zeros.Is this a req...
Hi I have two stm32wb55rg nucleo which i will use to transfer data via bluetooth for each other.I would like to use an external antenna like the ant0060. However, I did not notice any change in the receiving range after changing the gain antenna from...
Hi Everybody!New with STM32, i'm currently working on a project in order to combine black line detection with an AlphaBot and IA embedded with a TOF sensor, all of that with a Nucleo-WB55.Actually I would like to add a Bluetooth function to be able t...
I am trying to connect to a Polar HRM with a STM32WB55 Nucleo board by modifying the BLE_p2pClient example. I tested the example and it worked in connecting to another ST board. Then I modified the code to connect to the UUID of the HRM I got from th...
Hi,I developed an application with the Nucleo card which embeds an STM32WL55JCI6 starting from the "Sigfox_PushButton" example.The program uses 60 kB of flash and 8 kB of RAM and therefore works under the STM32WL55JCI6 which embeds 256 kB of flash an...
