Arctis 7 Pro - Battery Charge Level alway at 56%

[dmatta22201]

Description

I am having an issue in which the Arctis 7 Pro is always reported with a battery charge of 56%, regardless of actual battery level. Running

headsetcontrol --dev -- --device 0x1038:0x12ad --send 0x06,0x18 --receive

The response is consistently:

0x06 0x18 0x38 ...

where the ... is 6 bytes whose values vary, followed by a bunch of zero value bytes.

Looking at /devices/steelseries_arctis_7.c in the arctis_7_request_battery function, it looks like it is setting the battery level to the third byte...

    int bat = data_read[2];

    info.status = BATTERY_AVAILABLE;

    if (bat > 100)
        info.level = 100;
    else
        info.level = bat;

However the third byte is always 0x38 (decimal 56).

I am not sure how to interpret the next 6 bytes returned. Rerunning the command every 30 seconds or so produced the following:

0000 0000 0000 0000 0000 0000
0000 0xff 0000 0x06 0xc0 0000
0000 0xff 0000  0x06 0xc0 0000
0000 0xff 0000  0x06 0xc0 0xc0

Does anyone have a reference of what these bytes are and if they relate to battery levels?
