BLE Documentation for Services and Characteristics

[MGall.2]

Hello,

I am implementing a BlE client (central) to display the information being transmitted for a couple of ST SM32L4 boards.

So far, I am getting the information on my application but I don't have a way to determine what sensor that data corresponds to.

Is any documentation or profile for ST boards? I am particularly interested in the STM32L475 IoT Node board. I am using the examples provided with that board and I am able to connect and receive information but the data does not provide descriptor information for the characteristics.

Please advise.

Regards,

Marcelo
