bluetooth - How to add Serial Port Profile v1.2 in Bluez v5.5?

My OS is Yocto (2.4 rock). I checked to Bluez website, it supports spp(Serial Port Profile) v1.1.

I need to update it to v1.2 for Bluetooth certification, how to implement it?

By the way, both WIN 10 and Android Q support spp v1.2.

If you have any ideas, please let me know. Thanks a lot.
