Hello, I need to send data from STM32WB Nucleo to the computer (any symbol), I spend many days, but didn't find any simple example for that in Google. I was surprised usually I never had a problem like that...

Please, can you share a simple example of how to send data/symbol/something from STM32 WB to the computer via BLE

Regards,

Hi @IRakh.1​ , i have been there and done that.

Your struggle is normal.

Even if they share the same name BLE and bluetooth Classic are different beasts.

In bluetooth classic you would find a Serial profile port which acts as a transparent Serial transmission.

Well, bad news, in BLE there is no standard serial profile so you need to build your own(in fact, every BLE module provider has their own, including st).

Make sure you understand BLE things like characteristics, services, descriptors and all that first.

  • The fastest way for you to transmit bytes to your Phone it would be to use one of the BLE debugging tools on your phone like "LightBlue" or "ST BLE toolbox".

  • In Windows PC i just do a desktop app with QT Creator.

In addition to all this you could use Google Chrome's webBLE API to control the BLE from the web browser with javascript. https://www.hackster.io/javier-munoz-saez/controlling-this-blinky-boy-from-chrome-webble-0b9708
