ble authentication and pairing

It can still occur multiple devices are used to connect to the peripheral, but only used by users allowed to connect to that device. That is why we thought about a login to a remote server from the windows machine where we can download the pairing information for that specific device. That way only authorised users are able to connect.

We are currently on the track of using an open BLE connection and implement the authentication and encryption on the application level.

nice idea. But a requirement is that we can use the bluetooth features of windows, so no additional hardware is needed.

Is it a requirement that the peripheral is tied to a specific client from the very beginning? If it were acceptable that the device bonds to the first client it encounters, then you could use regular bonding over BLE. You could add an application level authentication method to make sure the initial bond is made to your application and not some phone app or such.

Another option could be some sort of USB dongle that have that bonding information stored / linked to the peripheral, and the peripheral have the central/dongle information stored.

thank you. But I do not see how this answers my question.

hello

When the pairing procedure has been completed, the following changes are displayed:

A log entry shows the new security level of the connection.
The connection info padlock changes to locked if the connection is encrypted.
The event view text turns green to indicate success.
