Abstract
A wireless communication apparatus that communicates data with an external wireless apparatus in a wireless communication range includes a controller and a wireless communication interface device is provided. The wireless communication interface device includes a transmitting unit that transmits response request data to the external wireless apparatus, a counter that counts time for determining whether or not a time limit for waiting for the response data has elapsed, a storage unit that stores the response data, a receiving unit that receives first response data from the external wireless apparatus and that instantaneously receives second response data without an instruction from the controller when the time limit has not elapsed, a frame length checking unit that checks a frame length of the received response data, and an error detector that performs error detection on the response data.
