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 ...
Hello ST - would you please clarify these two errata and share the missing formula from PM0271:Slot guard time (1.25 ms or 1.5 ms?The last sentence of 5.2 specifies a 1.25 ms guard time.5.2.2 specifies a 1.5 ms guard time and Figure 22 shows 1.5 ms g...
Hi, I use an Nucleo-32WL55JC1 with one MS5637 (pressure sensor). (The point is not the precise sensor but the I2C communication. )In CubeMX, I designed the pins : In main.c, I added : I2C_HandleTypeDef hi2c1;And in the main function : BSP_LED_Init(L...
Was anybody able to implement a custom BLE profile for the STM32WB55 using STM32CubeIDE v1.7 (or around) and the firmware package 1.11.1 (or around)? I would like to recreate and make publicly available this workshop. It is out-of-date.
I want to use an STM32WB module as a ble beacon receiver/detector so I can monitor beacons on my PC using a uart or USB vcom? Are there any examples that can help me and if "Yes" where can I find them?
All examples of the github repo are at least a few 10 of thousands lines of code big.I just want to share a few bytes of information over ble. Is there a really simple example without timeserver, freertos and that kind of stuff?Just like:start CPU2in...
Hi,I'm trying to make SRAM2a retention in standby mode work on my STM32WB55 device.As far as I can tell, the device enters and gets out of Standby as expected (the C1SBF and C2SBF flags are appropriately set when the MCU get sout of the low power st...
We accidentally bought a few Nucleo-WL55JC2 modules whereas we really wanted Nucleo-WL55JC1 modules. My understanding is that the JC2s are intended for AS433 applications. I would have expected the join to be unseccessful, though. However, we succe...
I am trying to use the pushbutton of NUCLEO-WB55RG and I tried coding it in both external interrupts and also as a gpio input. The pin configuration is correct. The same code is running on other Nucleo boards such as L496 and L432. But the code does ...
I have configured the stm32wb with 247 data transmission but in the receiver side the buffer seems like it transferred only 20 bytes in the notification. For note: The values are updated in the 255 sized cmd_buffer in the aci_gatt_update_char_value(...
I am developing a bootloader where it must install a new stack using the FUS (STM32WBxx). When I am debugging and I call into CPU2 to start the FUS, the JTAG loses connection and will not reconnect until I reset everything. Is there a way to handle...
