I-NUCLEO-LRWAN1 and STM32F767ZI problem with usart

Hi, I'm working on the Lora project. I have a STM32F767ZI board and an I-NUCLEO-LRWAN1 module. As I understood from the manual to the module. The module is programmed using AT commands via UART. I set up USART3 on my board to communicate with a PC th...

Bluetooth testing and certification for the new STM32WB5MMG module

Good day,So the STM32WB microcontrollers have all been tested and qualified with the Bluetooth Special Interest Group (SIG). (Search for "STM32WB" on here: https://launchstudio.bluetooth.com/Listings/Search).However, the new STM32WB5MMG module does n...

help with stm32WB BLE

Hello,I am a beginner with ble. I have worked with other stm boards in the past. I need help with the STM32WB baord.I used cube mx to generate the start up code. Enabled rf, rtc and everything.Enabled custom template in server modeadded a service and...

STM32WB LI-Ion battery-powered design for most effective power consumption

Hello, community!I need to design a device that can work from a single-cell Li-Ion battery (~500mAh) of at least 1.5 years. STM32WB55 has SMPS which can increase consumption efficiency, the maximum input voltage for SMPS is 3.6V but the battery volta...

HardFault in the workshop on blue thooght with 03-STM32W-WS__How_to_add_BLE_functionality_V2.2. I can turn on and off the blue led. When I press button 1, the cortexM4 goes well in the interrupt routine: void HAL_GPIO_EXTI_Callback.

After the Return instruction, the Cortex M goes into Hardflault.I use the STM32CubeIder 1.5.1.. It uses sequencer.c. I attach two screen prints:The:void HAL_GPIO_EXTI_Callback, where there is a breakpointand that of the fault analyzer:

STM32wb Unable to start the advertising

Hello Geeks!I'm playing with STM32WB.Actually, I'm using in one of our product as an SOCI'm using the Former version of the Cube packages, i guess "1.7.x"As we all know, the former version of the Cube packages was unstable and almost impossible to pl...

Unexpected triggering of HAL_UART_IRQHandler using HAL_UART_Receive_IT and HAL_UART_RxCpltCallback

Board: Nucleo-WB55I'm attempting to continuously interrupt when data is received via UART. The program is able to receive data when it is sent without fail, however the Rx interrupt is triggered when new data is not sent. I implement the following lo...

Ping Pong example on STM32WL55JC, sending data over a buffer with lora, when i want it to reveice, on which register is the receiving data writen? There should be a possibility to access this register where it receives the messages.

STM32WB55xx STM32WB35xx BLE 5.0 minimum required time for maximum throughput. Connection is getting lost during the transfer of data more than 100Kbytes.

Hello We are using STM32WB55xx STM32WB35xx Nucleo board with STM Ble stack. We want to transfer data around 2Mbytes after connection.After connection, we are only able to transfer around 100Kbytes of data after that connection is getting lost.What i...

Hello, I tried to write advertising and pasive scanning(both at the same time) application using STM32CubeMX.

Is it possible to pasively scan on this kit? Example with active scan works(BLE_p2pRouteur from git repo).Just to understand what I need - chip have to to advertise data while pasively scan all beacons around.Moreover in document PM0271 Rev 1, July 2...
