Is there a way to enable the feature notification when connection with the BLUENRG1 module took place? By default, the notification in module is disabled and can be turned on only from the PC.

Hi Igor,

notifications for a characteristic are sent from the GATT server only if the GATT client has

explicitly

enabled them by writing the related characteristic descriptor.

The rationale for this is reducing the power consumption, because sending the notifications when the client is not reading them would be a waste of energy for a battery powered device.

That's why you have to turn on the notifications from your client (the PC in your configuration).

Best regards,

Antonio

I understood everything, thank you. I assumed this, but I could not confirm this.
