@Mathieu
Thanks for the review and bring this up,
the reason behind this inconsistency is because it's how bluez5 doing it and I don't plan to modify too much upstream code when porting, upstream commit 6a394b2c7f19b53b630bef2e865f9bc289d4b75c says it's because D-Bus doesn't have a uint8 type, so they use uint16 instead and upstream still use uint8 internally.
