When transmitting a GATT communication request to the communication apparatus 151 after completion of pairing, the information processing apparatus 101 notifies the communication apparatus 151 of the link key stored in the storage area at the time of pairing processing. Upon receiving the GATT communication request, the communication apparatus 151 compares the link key stored in the storage area at the time of pairing processing with the notified link key, and confirms whether the apparatus of the transmission source of the GATT communication request is a paired apparatus. Upon confirming that the apparatus is a paired apparatus, the communication apparatus 151 starts information transmission/reception by GATT communication with the apparatus (information processing apparatus 101). Hence, after the pairing processing with the communication apparatus 151 is completed once, the information processing apparatus 101 can execute GATT communication with the communication apparatus 151 without input of the PIN code by the user.
