AT+IPHONEACCEV命令
该命令是用来提示蓝牙配件的电池状态,可以提示两方面:一方面是电池的电量百分比,一当面是蓝牙配件的当前的充电状态。该命令的说明见下方:

格式:AT+IPHONEACCEV=Number of key/value pairs,key1,val1,key2,val2,…

附带的参数的含义分别是:①键值对的数目:接下来的参数文本的数量;②接下来就是键值对分别是:键值为1表示的是电量,该键所对应的值就是电量百分比,使用字串”0“到”9“表示;键值为2表示的是充电状态,0表示不在充电,1表示正在充电。
举例:AT+IPHONEACCEV=1,1,3 该AT指令就说明附带了一个键值对(第一个参数是1);键是1,那么表示的是电量,且电量是40%(因为使用的是0~9,这里3就对应的百分比是40%)。
