Would to request improvements on HFP dissection: recognize value as battery percentage. On my Samsung Galaxy Buds, +BIEV is used to receive battery level of the earbuds over bluetooth. The format is as follows: "AT+BIEV=2,95" Where the 2 is the value to design that next comes common battery level. After the comma there can be any integer value (preferably 0~100), which represents the minimum battery level shared by both earbuds, not including the charging case. One of them can be disconnected. Example: left=100, right=95, charging case=40 => reported battery level is 95. After the decimal values closes with 0x0d9c.
