Abstract
The present invention provides an information processing apparatus and a method of deciding a correction amount for correcting the radio field intensity of received radio waves in the information processing apparatus. The information processing apparatus receives a BLE (Bluetooth Low Energy) packet transmitted by an external apparatus, and displays a screen for deciding a correction amount for correcting the radio field intensity of the BLE packet. If a user inputs an instruction for deciding the correction amount via this screen, the correction amount is decided based on the radio field intensity of the received BLE packet and a reference value.
Claims21
A method of performing a correcting process of information indicating a reception level that is estimated based on a received power of a radio wave that carries a BLE (Bluetooth Low Energy) packet in an information processing apparatus that receives the BLE packet from an external apparatus, the method comprising:
- displaying a first screen including a message for prompting a user to position the information processing apparatus at a predetermined distance from an image forming apparatus;
- arranging data to be used in the correcting process based on at least the received power of the radio wave that carried at least one BLE packet that was received by the information processing apparatus, while the first screen is being displayed, in accordance with receiving a user operation for the correcting process via the first screen;
- and
- correcting the information indicating a reception level of a radio wave that carried the BLE packet that was received after the data has been arranged, using at least a received radio intensity of the radio wave that carries the BLE packet that is received after the data has been arranged, and the arranged data.
A non-transitory computer readable storage medium storing a program for causing a processor of an information processing apparatus that receives a BLE (Bluetooth Low Energy) packet from an external apparatus to perform a correcting process of information indicating a reception level that is estimated based on a received power of a radio wave that carries the BLE packet, the program comprising code to execute:
- displaying a first screen including a message for prompting a user to position the information processing apparatus at a predetermined distance from an image forming apparatus;
- arranging data to be used in the correcting process based on at least the received power of the radio wave that carried at least one BLE packet that was received by the information processing apparatus, while the first screen is being displayed, in accordance with receiving a user operation for the correcting process via the first screen;
- correcting the information indicating a reception level of a radio wave that carried the BLE packet that was received after the data has been arranged, using at least a received radio field intensity of the radio wave that carries the BLE packet that is received after the data has been arranged, and the arranged data.
The non-transitory computer readable storage medium according to claim, wherein the data to be used in the correcting process is arranged correction amount is decided based on a difference between the received power of the radio wave that carried at least one BLE packet that was received by the information processing apparatus while the first screen is being displayed radio field intensity of the first BLE packet and a reference value corresponding to the predetermined distance.
An information processing apparatus that receives a BLE (Bluetooth Low Energy) packet from an external apparatus and performs a correcting process of information indicating a reception level that is estimated based on a received power of a radio wave that carries the BLE packet, the information processing apparatus comprising:
- a memory that stores a program;
- and
- a processor that executes the program to perform:
- displaying a first screen including a message for prompting a user to position the information processing apparatus at a predetermined distance from an image forming apparatus;
- arranging data to be used in the correcting process based on at least the received power of the radio wave that carried at least one BLE packet that was received by the information processing apparatus, while the first screen is being displayed, in accordance with receiving a user operation for the correcting process via the first screen;
- correcting the information indicating a reception level of a radio wave that carried the BLE packet that was received after the data has been arranged, using at least a received radio field intensity of the radio wave that carries the BLE packet that is received after the data has been arranged, and the arranged data.
A method of correcting data to be used by an information processing apparatus that estimates a distance between the information processing apparatus and a Bluetooth Low Energy device that transmits a Bluetooth Low Energy advertising packet, the method comprising:
- displaying a screen, the screen including a message for prompting a user to bring the information processing apparatus closer up to a predetermined distance from the Bluetooth Low Energy device that transmitted the Bluetooth Low Energy advertising packet;
- correcting data, to be used for estimating the distance, using a radio field intensity of at least one Bluetooth Low Energy advertising packet received while the screen is displayed in accordance with receiving a user operation for correcting the data via the screen;
- and
- controlling to estimate the distance corresponding to the received Bluetooth Low Energy advertising packet using at least a Bluetooth Low Energy advertising packet received after the correction of the data is completed and the corrected data.
