Abstract:
An environment information measuring device (200) transmits to a communication terminal (100) an advertisement including a “no_data” flag indicating that there is no data that should be transmitted, when a transmission condition indicating the necessity of data transmission is not satisfied. When the “no_data” flag is not included in the advertisement transmitted by the environment information measuring device (200), the communication terminal (100) executes a connection action process with the environment information measuring device (200) and accomplishes sending data to and receiving data from the environment information measuring device (200). In contrast, when the “no_data” flag is included in the advertisement transmitted by the environment information measuring device (200), the communication terminal (100) does not execute the connection action process with the environment information measuring device (200). In this case, the communication terminal (100) does not accomplish sending data to and receiving data from the environment information measuring device (200).
Abstract:
A radio communication terminal receives position information showing a position of another radio communication terminal. The radio communication terminal obtains, from the position information, a terminal ID of the radio communication terminal, and a beacon ID for identifying the predetermined location nearest to the radio communication terminal. The radio communication terminal accepts the predetermined location designated by a user. The radio communication terminal determines as a communication partner terminal, the other radio communication terminal that is nearest to the accepted predetermined location based on the terminal ID and the beacon ID. The radio communication terminal performs communication with the determined communication partner terminal.
Abstract:
A peripheral transmits an advertisement including an order of connection priority of when a central is connected to the own apparatus. The central receives the advertisement. The central acquires the order of connection priority included in the received advertisement. The central controls transmission of a connection request signal to the peripheral based on the acquired order of connection priority. In response to the transmitted advertisement, the peripheral receives a connection request signal transmitted from the central. According to the connection request signal, the peripheral establishes connection with the central.
Abstract:
A moisture status measuring device includes a moisture sensor, a drainage sensor, and a moisture status acquirer. The moisture sensor outputs an output value according to an amount of moisture contained in soil housed in a container that includes drainage holes. The drainage sensor detects water discharged from the drainage holes. The moisture status acquirer acquires moisture status information expressing the current moisture status of moisture in the soil on the basis of the output value from the moisture sensor at the time when the drainage sensor detected water and the current output value from the moisture sensor.
