i have some questions for ble conneciton between smartphone with bluetooth earphone.
after pairing/bonding the bluetooth earphone, when i turn on bluetooth earphone, my smartphone automatically connect to the bluetooth earphone.
how it can be? the smartphone periodically try to connect (send connect request packet) to paired devices?
i don't think that job includes advertising/scan because the connection has completed so quickly right after bluetooth earphone turn on.
maybe.. i think the smartphone periodically try to connect to paired devices..
is it right?
