RE: Connecting BLE Bonded/Paired peripheral that is not advertising

Hi Barbieri,

I'm afraid that there is no way to establish a connection without doing advertising. It's the only way that the 2 devices can agree on syncing the timing and the RF channel it should communicate in the connection.
However, it's possible to do a directed advertising to a specific central that it's bonded before. The directed advertising packet will not be shown on other device (it's still scannable, but most device will not display the directed advertising packet that is not destinated at its own address).

You can have a look at our ble_app_hids_mouse project for an example.
