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,I'm trying to figure out why setting the MTU stops the ACI_ATT_READ_BY_GROUP_TYPE_RESP_VSEVT_CODE event from ever firing. This essentially breaks everything.case HCI_LE_CONNECTION_COMPLETE_SUBEVT_CODE: /* USER CODE BEGIN EVT_LE_CONN_COMPLETE ...
Hey,I am trying to make a device which connect to an app using stm32wb15. Everything works properly, but I want to make it so that when the device becomes disconnected, i can use a button to broadcast BLE so that i can connect through an app again. I...
Hello! I'm working on a custom PCB that uses the STM32WB1MMCH6TR module, which was chosen specifically because of its integrated antenna. Unfortunately, with the first prototypes I'm getting extremely poor range with BLE, usually <-80 dBm even just a...
Hello,I have STM32-WBA55CG connect with MEMS sensor. STM32 board will send the messages back to terminal through USART. The WBA55CG is right now connected to stationary power source. It would be nice if someone can give some ideas, how to transform i...
Hello,I'm using WBA55CG Board and i have tried to flash this example STM32WBA Bluetooth® LE – Serial communication - stm32mcu to the STM32. The flashing step is completed, i could connect the board through ST BLE Toolbox on iOS. However there is no s...
Hi everyone, I was hoping to find some help in locate a simple tx example for the stm32wl33 using a freertos task. I have tried to move functions in the mrsubg basic transmit example to a task but seems to not function properly. Does not transmit and...
Hello,I am having trouble with a call to HAL_SAI_Transmit_DMA() to transfer data to our audio codec.Buffer stored in RAM: unsigned char sweep_tone[80000]. For the sake of this demo, I've filled the buffer with 16-bit samples counting from 0 - 39999.T...
I followed the tutorial from this video: https://www.youtube.com/watch?v=6JPys9B497c to practice setting up BLE.After flashing to the NUCLEO-WBA55CG, the ST BLE Toolbox app still cannot detect the device.I also noticed that after it executes: UTIL_LP...
Dear Sir,I am working on reading values from 10 ADC channels of the STM32WB55CGU6 (WeAct Studio board). However, I am not getting the correct voltage readings. Please note the following details about my setup:I am using USB (Virtual COM Port) to prin...
Hello folks, I've seen a similar topic(link) on this forum, but it had no solution, I'll take my chance and see if you could offer me some tips on how to debug this. I've designed a custom "break-out" board for STM32WB5MMG and I'm trying to communica...
