Light Blue App acknowledgement in STM32WB55?

[Pluto7]

Hi All,

I have flashed custom BLE profile code to STM32WB55 and sending dummy values over a service. I am able to see data in the LightBlue App.

In LightBlue Application, when READ button is pressed, it displays the data that was sent from firmware.

My question is:

Does the BLE firmware running in STM32WB55 receives some kind off command when the READ button in application (Light Blue) is pressed?

If yes, how to debug that?

If not, what is the flow of receiving data in the App. Is it independent of the press / not press of the buttons on application?

I am a beginner in BLE deveopments, so please pardon me.

Thanks and Regards,
Pluto
