Can't find bluetooth packages

[zital debian]

Hi, reading the docs: https://docs.onion.io/omega2-project-book-vol1/bluetooth-audio-speaker.html

opkg update
opkg install bluez-libs bluez-utils

trying to install bluetooh packages:

root@Omega-382B:~# opkg update
root@Omega-382B:~# opkg install bluez-libs bluez-utils
Unknown package 'bluez-libs'.
Unknown package 'bluez-utils'.
Collected errors:
 * opkg_install_cmd: Cannot install package bluez-libs.
 * opkg_install_cmd: Cannot install package bluez-utils

Previously i flashed this bin in my omega2+: http://repo.onioniot.com.s3.amazonaws.com/omega2/images/omega2p-v0.3.4-b259.bin

Surfing the packages web: http://repo.onioniot.com/omega2/packages/

there are only packages in the base path.

some help please? thank you
