When the first connection is established with a slave, the master determines one channel selected from three advertising channels, as a channel used for establishment of the subsequent connection with the slave, and notifies the slave of the one channel. When the first connection is established with the master, the slave transmits an advertise in the three advertising channels. Further, when the second or subsequent connection is established with the master, the slave transmits the advertise in the one channel notified of from the master. |
