Connecting BLE Bonded/Paired peripheral that is not advertising

abe

Hi, I developed a BLE and Zigbee custom product, starting from nRF5 SDK for Thread and Zigbee v3.2.0.
On BLE side, it connects with Mobile or Tablet using Pairing with bonding.
The question is: there is a way for Mobile/Tablet to connect the peripheral previously paired and bonded even without Advertising?

Waiting for your help, best regards

    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.
