How to make short name over 10 characters via mgmt?

[killerlife]

Hi,
I run a gatt server on linux and set it name of 20 characters. It only display 10 characters when I scane the device.
I check with hcitools, it shows the name and short name. The name is OK, but the short name just show 10 characters.
I check the bluec source code, the MGMT_MAX_SHORT_NAME_LENGTH limit short name to 11 characters with a terminal character in mgmt.h
I change the value to (30 + 1) and rebuild bluez. But it not work.
How to make it support large short name?
Thanks.

@killerlife how about not use the MGMT interface and instead use something like bluetoothctl> advertise.name?
