Radio transmitting apparatus and radio receiving apparatus to monitor residual capacity of a battery
First Claim
1. A radio transmitting apparatus comprising:
- a power supply voltage measurement unit that measures a power supply voltage;
a transmission power determination unit that determines a transmission power based on the power supply voltage that has been measured; and
a radio transmitting unit that transmits by radio a plurality of advertisement packets including transmission power information indicating the determined transmission power,wherein a residual capacity of a battery is represented by the plurality of the advertisement packets and a combination of the transmission power information of the plurality of the advertisement packets indicates the residual capacity of a battery.

Abstract
A radio apparatus that allows a user to check a state of a power supply is provided. A radio transmitting apparatus 10 includes a power supply voltage measurement unit 11 that measures a power supply voltage, a transmission power determination unit 12 that determines a transmission power based on the power supply voltage that has been measured, and a radio transmitting unit 13 that transmits by radio an advertisement packet including transmission power information indicating the transmission power that has been determined at the transmission power that has been determined. A radio receiving apparatus 20 includes a radio receiving unit 23 that receives the advertisement packet and a power supply state detection unit 21 that detects the state of the power supply of the radio transmitting apparatus 10 based on the transmission power information included in the advertisement packet.
