Claims20
A peripheral device, comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor configured to:
- broadcast, using the transceiver, a first advertising packet requesting a wireless connection;
- receive, by the transceiver from a first host device, a first response, in response to the first advertisement packet;
- establish a first connection with the first host device, in response to receiving the first response;
- initiate an authentication procedure of the first host device based on an identity of the first host device, after establishing the first connection with the first host device;
- and
- broadcast, using the transceiver, a second advertising packet requesting another wireless connection, without terminating the first connection with the first host device, in response to determining that the first host device is not authenticated during the authentication procedure.
