Hide Bluetooth Broadcast

[YLmaz]

Hello, we are working on Bluetooth. We want to keep the Bluetooth connection private. Not everyone should see the link. Especially after a connection is established with a device, other devices should not see and detect this broadcast. How can we take this security measure? Is this feature available on your devices? I would be glad if you inform me.

Have a nice day.

Hi. 

We want to keep the Bluetooth connection private. Not everyone should see the link.

Not sure if I understand what you mean by private?

After the link has been established and you pair and bond with your device, you can encrypt the link to keep the data transmitted safe. 

______________

As for the broadcast/advertisement of the device; This can not be "hidden". You can, however, advertise using a whitelist. It is still possible to see advertisements even when you are using a whitelist. Advertisements are not encrypted or "invisible" for unbonded devices, as they use the same protocol and the same channels as the devices that are not bonded/using whitelist. The difference is that you will not be able to connect to a device that claims to be using whitelist if you are not on that whitelist. The whitelist itself is not broadcasted, so the bonded device will have to know whether or not it already knows the advertising device or not.

Please let me know if I misunderstood your question. 

Br, 
Joakim

Hello,

Thank you for answer.

Wifi modems can Hide SSID, and if a device now SSID can connect it.  We need like this. Server making broadcast but no one can see it. Our client know this hidden server UID and connects. 

How can we provide such a solution to our customer?

Are you developing a WIFI modem? Or are we talking about BLE here?

If you are talking about BLE, refer to my previous answer.
