Main body device, method of controlling main body device, operation device, method of controlling operation device, and recording medium

A method of controlling a main body device that communicates wirelessly with an operation device and a communication device, the operation device being capable of transmitting and receiving a signal in a first communication scheme and capable of transmitting a signal in a second communication scheme different from the first communication scheme, the communication device being capable of transmitting and receiving a signal in the first communication scheme,

• the main body device including:
• a first communicator for transmitting and receiving a signal in the first communication scheme;
• and
• a second communicator for receiving a signal in the second communication scheme,
• the method of controlling the main body device comprising:
• determining, by communicating with the communication device via the first communicator, whether it is possible to determine a timing of transmitting or receiving a signal to or from the communication device via the first communicator;
• in response to determining that it is not possible to determine the timing, executing a switching process that causes the operation device to transmit an operation signal in the second communication scheme;
• executing a process in accordance with the operation signal received via the second communicator;
• repeatedly transmitting a polling signal for synchronizing with the operation device to the operation device via the first communicator;
• and
• in the switching process, transmitting the operation signal in the second communication scheme, by stopping transmitting the polling signal.

A main body device that communicates wirelessly with an operation device and a communication device, the operation device being capable of transmitting and receiving a signal in a first communication scheme and capable of transmitting a signal in a second communication scheme different from the first communication scheme, the communication device being capable of transmitting and receiving a signal in the first communication scheme, the main body device comprising:

• a first communicator for transmitting and receiving a signal in the first communication scheme;
• a second communicator for receiving a signal in the second communication scheme;
• and
• a controller that executes a process in accordance with an operation signal transmitted from the operation device and received via the first communicator or the second communicator, wherein
• the controller:
• determines, by communicating with the communication device via the first communicator, whether the controller can determine a timing of transmitting or receiving a signal to or from the communication device via the first communicator in coordination with a timing of receiving the operation signal from the operation device via the first communicator;
• and
• in response to determining that the controller cannot determine the timing, executes a switching process that causes the operation device to transmit the operation signal in the second communication scheme.
