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 using STM32CubeProgrammer trying to correctly start BLE stack.MPU: STM32WB50CGFUS was successfully updated to latest version 1.2.0.0.The bin file (BLE_Stack_full_fw.bin (v1.13.0) was successfully flashed on the address 0x080C7000. https://github...
I have changed my service characteristic from CHAR_PROP_WRITE to CHAR_PROP_WRITE_WITHOUT_RESP.(following android issues) But, when I try to write it , using a stm32wb55 dongle (ACI_GATT_WRITE_CHAR_VALUE) , I get : ACI_GATT_ERROR_RESP_EVENT ( 0x03: W...
Hi,I'm using a Stm32wb5mmgh6tr embbeded MCU for sharing data wireless via BLE. I just saw on the AN5185 application note document that wireless stack is not installed by default. So I've started FUS and then installed the latest version of the WS wit...
Hi everyone,I'm trying to add a new file Alarm.c to my project. I added it in the Core>Src folder but I want to use it in a custom_app.c file that is located in another folder (STM32_WPAN>APP) as I use BLE. I included it to this file but when I compi...
I'm new to BLE and working on a project where I need to create a link from my STM32WB15 to a 3rd party IMU sensor. I have no access into the sensor, but I have the UUID's and advertisement data structure.In STM32CubeProgrammer I set the parameters fo...
So is this chip now completely released or not?The product page is available and says it is active, but it does neither offer a reference manual nor a price indication.Form what I understand it is basically a BlueNRG-LPS with more Flash. Meaning the ...
Hello, I am working with STM32WBA52CG as a central and I want to read the RSSI from the incoming advertising packets. The RSSI value should be a negative value in dBm, however it is defined as uint8_t in the AdvertisingReport_t structure. Can someone...
Hi,I started a Circuit/PCB design with STM32WL55CCU (UFQPN48) to work at 433MHz.I was referred to ST design for low band/Hight power and to AN5457.But I am style missing for some information:What is the PA impedance at 433MHz for UFQPN48 package?In A...
I have a program that requires a 30 second wake up period to feed a watchdog but use as little power a possible. To initiate the LPTIM using an external 32.768kHz watch crystal I am doing this:__HAL_RCC_LPTIM1_CONFIG(RCC_LPTIM1CLKSOURCE_LSE); //LSE L...
Hi,I am current reading the material to develop a LoRa application. My PCB is wicked small, therefore the chip-antennas wont have a good ground plane and therefore bad efficiency.While reading about the RX-path, I stumbled upon AN5457 where in figure...
