Don´t know if anybody else did it... but I got Bluetooth running by modifying the device tree and adding support for communication between the RTL8723BS and UART1 and loading the needed RTL8723B firmware.
2) Run sudo ./compile with your favorite config (Desktop/server/blablabla)
3) Flash the image to an SD card or eMMC module.
4) Start your Pine64 H64 model-B
4) Connect to a network and run the firmware update/upgrades (armbian-config) and install the Bluetooth tools.
5) DO NOT ENABLE SERIAL 1 !!!! in armbian-config
6) Download the next git repo to your board: https://github.com/lwfinger/rtl8723bs_bt.git
7) Unpack the archive, run make
8) Copy the next firmware files to /lib/firmwares/rtl_bt:
sudo cp rtlbt_fw_new /lib/firmware/rtl_bt/rtl8723bs_fw.bin
sudo cp rtlbt_config /lib/firmware/rtl_bt/rtl8723bs_config.bin
9) Reboot
