For more than a year, I often found that the org.bluez.Battery1 dbus interface randomly failed to obtain the battery level of some devices. When this happens, it is always accompanied by a "Trying to update an unregistered battery" log. Finally, I found a bug in battery.c:parse_battery_level(). Except when called for the first time, it will wait until the battery percentage changes before updating the value in the dbus interface. For BLE devices, changes in battery percentage will take a long time, which is enough for the device to disconnect/reconnect multiple times due to sleep/wake-up. And every reconnection has a chance to cause "Trying to update an unregistered battery". This is a new version of the previous patch, fixes the style problem. > id: 20240723082843.184915-1-YanceyChiew () gmail ! com Yancey Chiew (1): profiles/battery: Fix batt random lose percentage profiles/battery/battery.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) -- 2.45.2
