Hide Characteristics values before Bound

[code_hard]

Hello,

I am going my project with NRG51822 in SDK 11. I build a android app that can connect to my device and access vendor specific service.

My device dedicates one button for BLE connection, and it will trigger limited advertising on button pressed. Android could connect to device in 30 secs after BLE button pressed, and it will perform bond procedure after "Just Works" pairing.

I want characteristics that in vendor specific service can not be accessible before bound, what should I do? Does any example in SDK 11 has the similar procedure that I could refer to?

Regards,

Interesting question.

AFIK. Characteristic(s) details are transferred after the connection has been made.

The advertising packet just contains the service UUID number, and nothing about the characteristics.
