ABSTRACT:
A communication apparatus (1) is a primary station for communicating with a secondary station, and includes: a first protocol control section (111) for transmitting, at a time when communication connection is to be established with the secondary station, (i) a station discovery command with which to confirm a presence of the secondary station, and (ii) a first connect request command, after the station discovery command is transmitted, so as to carry out connection processing; second protocol control means (112) for transmitting, at a time when communication connection is to be established with the secondary station, a second connect request command so as to carry out connection processing; and a protocol switching section (113) for (i) causing the first protocol control section (111) to initially transmit the station discovery command, and in a case where a response to the station discovery command has not been received after an elapse of a predetermined time since the station discovery command was transmitted, (ii) causing the second protocol control section (112) to transmit the second connect request command.
