Hi Damian,
I think, it will be better to open a issue on bugtracker with the pcap
Cheers
Sorry for the duplicate mail, Gmail app is a mess and doesn't allow to
convert to plain text.
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.
