STM32WB controllers are dual-core processers where Arm® Cortex®�?M4 core running at 64 MHz for application and Arm Cortex�?M0+ core at 32 MHz for network or BLE. To transmit data through BLE aci_gatt_update_char_value() Function used which blocks Ar...

Hii guys,we are using the STM32WB50 controller in our project. Stream 23000 bytes continuously in a second(46bytes after every 2-millisecond interval) using Bluetooth low energy system provided by the STM32WB microcontroller.To successfully transmit ...

Hello friends,I am working on STM32WB on-chip Bluetooth low energy system to transmit data from server to client using notification property.I want to transmit 46 bytes at the rate of 500Hz without any packet loss, to achieve this I have updated the ...

Your updates are always valuable to me, but I've always suspected that update firmware won't bother a device already running.The same happened in the STM32WB new update (FW version 1.12.1), in this update BLE and GPIO interrupts are not working simul...

I want to read LIS2DTW12 data using SPI which is also shared with another device, can I use the LIS2DTW12 CS pin as chip select and operate devices one by one.because according to the LIS2DTW12 datasheet:State of CS1: SPI idle mode / I²C communicatio...

Thanks a lot @jro , that helped.It is surprising to see that community members understand the environment and the problems that might arise better than ST employees themselves.Is there any application notes or something similar elaborating on such s...

Re: I am using "P-NUCLEO-WB55". My application needs BLE over RTOS, So I tried the example code of "BLE_HeartRateFreeRTOS" ,I just put blinking led code in default task but I am not able to observe the output.(Initialization for LED PIN is added)
